Dual time base generator: including A time base (main time base) and B time base (auxiliary time base), supporting three working modes (independent sweep, dual sweep, delayed sweep).

Scanning speed range:

A time base: 1 μ s/Div to 5s/Div (21 levels 1-2-5 sequence), 10x magnification (A SWP MAG) to reach 100ns/Div;

Working mode and operation process

1. Three core working modes

Mode name trigger condition applicable scenario key operation steps

Independent sweep mode (A or B works separately) – Normal trigger (AUTO TRIG pops up): The trigger signal must be ≥ 15Hz and the LEVEL must be correct

-Single trigger (A SINGL SWP pressed): Only 1 sweep frequency, A RESET is required to reset the regular time measurement of simple signals, non repetitive signal photography 1. Press the A or B button of MODE

2. Choose TRIGGERING SOURCE-COUPLING/SLOPE

3. Adjust LEVEL to stable display, press A RESET for standby in single mode

Dual sweep mode (A+B working simultaneously) A trigger source corresponds to the left vertical plugin, B trigger source corresponds to the right vertical plugin, and trigger parameters need to be set separately to observe two signals (or different scan speeds of the same signal) simultaneously. 1. Press the A+B button of MODE

2. Set the PLAY to ALT (fast scanning speed) or CHOP (slow scanning speed)

3. Adjust the Seconds/DIV and trigger parameters of A/B separately, and use INTERN BAL to balance the brightness

Delay sweep mode (B time base delay start): After triggering A time base, start B time base (or wait for triggering after B time base delay) signal local amplification, time difference measurement, pulse jitter measurement. 1. Press the A INTEN-B DLY’D button of MODE (in conjunction with A/B)

2. Set A Seconds/DIV (delay benchmark) and DELAY TIME MULT (delay multiplier)

3. Adjust the B Seconds/DIV (delayed sweep speed) to be faster than the A time base to avoid logic errors

2. Sweep frequency amplification operation (taking 100x amplification as an example)

Preparation for dual sweep mode: Press the A+B button, connect the left/right vertical plugs to the same signal, set A Seconds/DIV to 0.1ms/Div (display complete waveform);

Delay mode start: Press A INTEN-B DLY’D and use DELAY TIME MULT to locate the enhanced segment to the pulse that needs to be amplified;

B time base setting: B Seconds/DIV is set to 1 μ s/Div (1/100 of A scan speed), and at this time B time base displays a 100x amplified waveform of A time base enhancement segment;

Calculate magnification factor:

Magnification factor=B Seconds/DIV settings

A Seconds/DIV setting= 1×10 −60.1×10 −3=100

4、 Application scenarios and examples

1. Time difference measurement (interval between two pulses)

Signal access: The left/right vertical plug-in is connected to a signal containing two pulses, in dual sweep mode (A+B pressed), with Volts/Div set to 2 grid amplitudes;

A Time Base Setting: A Seconds/DIV is set to 0.2m/Div (displaying the multi grid distance between two pulses), and the trigger parameter is adjusted to stable display (using CHOP mode for slow scanning speed);

Delay mode start: Press A INTEN-B DLY’D, set B Seconds/DIV to 2 μ s/Div (1/100 of A scan speed), and strengthen the segment length by about 0.1 grid;

Delay positioning: DELAY TIME MULT first locates the rising edge of the first pulse (reading 1.31), and then locates the second pulse (reading 8.81);

Calculate time difference:

Time difference=(8.81-1.31) × 0.2ms=1.5ms

.

2. Pulse jitter measurement

Signal access: Left/right vertical plug-in access pulse signal, dual sweep frequency mode, Volts/Div set to 4 grid amplitude;

Delay mode start: Press A INTEN-B DLY’D, DELAY TIME MULT locate the pulse to be tested, and set B Seconds/DIV to 0.2 μ s/Div (covering the pulse front);

Jitter calculation: observe the horizontal offset of the pulse in the B time base (example 0.5 grid),

2. Panel controls and interfaces (key functions)

Control/Interface Function Description

POSITION adjusts the trajectory position on the screen

HF -3dB/LF -3dB – HF -3dB: 1-3-10 sequence with 7 levels (0.1kHz-1MHz), reducing the upper bandwidth limit and improving signal-to-noise ratio

3. Basic operation steps

Installation and startup:

Insertion: Align the plug-in guide rail with the 5100 series module compartment (priority vertical compartment: center/left; X-Y operation can be inserted into the horizontal compartment), and the panel should be level with the oscilloscope;

Power on: Adjust the oscilloscope brightness to the lowest level → Power on → Preset time base (2ms/Div) and trigger (automatic trigger).

Initial setup:

Set PLAY to ON,+/- input coupling to DC+GND, POSITION and STEP ATTEN BAL to median, HF/LF-3dB to full bandwidth, VOLTS/DIV to 50mV/Div, and variable gear to CAL (clockwise to bottom).

Preheating and trajectory adjustment:

Preheating: Short term DC measurement for 5 minutes, long-term DC measurement for 15 minutes;

Adjust the brightness to normal, and the trajectory should be near the center of the scale. Use POSITION to move the trajectory to 2 grids below the centerline.

Example of signal measurement:

Single ended DC coupling:+input connected to 400mV peak to peak calibration signal → release+GND → display 4 grid square waves (bottom alignment step 3 reference line);

Single ended AC coupling: POSITION moves the trajectory from bottom to center → presses AC → the trajectory shifts downward by about 2 grids (to the average value);

Differential AC coupling:+/- input connected to dual input cable → – input set to AC → display straight line (common mode signal suppressed).

4. Key precautions

Input protection: The maximum voltage of the input FET gate is ± 12V (diode clamp), and the input fuse will melt when the signal source current exceeds 1/16A;

Pre charge (PRE CHG): When measuring AC signals containing DC components, first connect the AC+GND signal → wait for 1 second for charging → release GND to avoid damaging the signal source due to coupling capacitor charging current;

High impedance input: When VOLTS/DIV is in the 50mV-10 μ V range, removing the circuit board jumper can disconnect the 1M Ω ground resistor, achieving high impedance input (requiring the signal source to provide a DC path for FET gate current).

1. Overall block diagram path

Signal → Input coupling (AC/DC/GND) → Input attenuator (1X/100X, frequency compensation) → Pre amplifier (differential structure, floating ground power supply) → Low frequency limiting circuit (LF-3dB switching) → Gain switching stage (VOLTS/DIV control) → Offset generator (DC OFFSET) → Isolation stage (emitter follower) → Output amplifier (push-pull structure, POSITION adjustment) → Trigger signal amplifier (output to time base plugin, 0.25V/display panel).

2. Analysis of core circuit modules

Input attenuator:

Attenuation ratio: VOLTS/DIV 0.1V-5V range with 100X attenuation, 10 μ V-50mV range with 1X attenuation;

Features: Frequency compensation, maintaining 1M Ω//47pF input characteristics, balancing common mode signals through R132 (Atten DC CMR).

Pre amplifier:

Structure: Two identical operational amplifiers form a differential circuit (Q150A/B, Q190A/B, Q200A/B);

Floating power supply: composed of Q170/Q176 (constant current source) and VR173/175/176 (Zener transistor), it maintains the stability of the amplification device operating point and improves CMRR as the common mode signal changes;

Gate current compensation: Regulate R121/R127 to offset FET gate leakage current (≤ 100pA) and avoid high-sensitivity offset (such as 100pA × 1M Ω=100 μ V offset in 10 μ V/Div mode, which may cause trajectory offset screen).

DC offset generator:

Structure: Q240/Q244/Q246A/B form a voltage comparator, with VR251 (transistor) providing a reference voltage;

Function: By adjusting COARSE (R260) and FINE (R268), offset current is generated to cancel the DC component of the input signal, with a maximum cancellation of 0.5V.

Output amplifier:

Structure: Push pull amplifiers Q348/Q352, R351 (GAIN) adjust the total gain to match the requirements of the host;

Position adjustment: Q360/Q362 (positioning current drive), R360 (POSITION) changes the current to adjust the static position of the CRT beam.

Calibration (Section 3)

Turn the variable gear to COUNTERCLOCKWISE, with a display amplitude of<2 grids, and then turn it back to CAL.

VOLTS/DIV accuracy check:

Overview of Instrument Core

(1) Hardware structure

Plugin compartment: There are a total of 3 compartments that can accommodate 5000 series plugins (without N suffix plugins supporting display readings), 2 vertical compartments (left and middle) for amplifier plugins, and 1 horizontal compartment (right) for time base plugins. The combination of plugins determines the functionality of the measurement system.

Key controls:

Display related: INTENSITY adjusts the brightness of the trajectory, READOUT INTENS only adjusts the brightness of the reading part (the reading system fails when counterclockwise to the bottom), FOCUS controls for clear display, and BEAM FINDER compresses the trajectory to the scale range.

Power supply and calibration: The power switch (POWER) controls the power on/off, and the internal calibrator (CALIBRATOR LOOP) provides a square wave signal with a voltage of 400mV (± 1%) and a current of 4mA (± 1%), with a frequency of twice the power supply frequency, for calibration and probe compensation.

External interface: EXT INTENSITY INPUT interface receives Z-axis modulation signals (DC coupling,+5V enhanced brightness, -5V reduced brightness, maximum safe input ± 50V, frequency range DC to 2MHz).

(2) Core functions

Display mode:

Alternate mode: The time base plugin display switch pops up and switches between the activated plugin/channel with each CRT scan, suitable for high-frequency signals.

Chop mode: When the time base plugin display switch is pressed, it electronically switches between channels at a rate of 100kHz, suitable for displaying low-frequency signals or single event phenomena.

X-Y operation: Install 5A series amplifiers or 5B series time base plugins with amplifier channels in the horizontal cabin to receive X signals, and 5A series amplifiers in the vertical cabin to receive Y signals, achieving signal comparison display.

Grating display: Both the left vertical cabin and the horizontal cabin are equipped with 5B series time base plugins. The scanning speed of the vertical cabin is slower than that of the horizontal cabin, and brightness modulation is achieved through EXT INTENSITY INPUT, which can simulate TV display.

Reading System: Only supports 5400 series plugins, displaying alphanumeric information in real-time with analog waveforms on CRT. Each plugin’s reading occupies a fixed position (channel 1 is indexed at the top, channel 2 is indexed at the bottom), displaying up to 6 readings (option 3 can select 8 readings). The reading interruption waveform display is only about 20 microseconds/character.

Operation Guide

(1) First operation process (19 steps in total, with the following key steps)

Plug in preparation: Install 5A series amplifier plugs in the left/middle vertical cabin and 5B series time base plugs in the horizontal cabin.

Installation and wiring

4.1 Installation environment requirements

Temperature: Operating environment temperature * * -10 ℃ -50 ℃ * *. When the ambient temperature is greater than 40 ℃, the warning label on the top of the equipment should be removed and the rated output current should be reduced (such as the current of the 2007P model dropping from 4A to 3.6A at 40-50 ℃);

Humidity: Relative humidity of 20% -93%, no condensation;

Vibration: Vibration acceleration<5.9m/s ² (10-55Hz), avoid installing near strong vibration equipment such as machine tools;

Other: No dust, corrosive gases, oil mist, keep away from heat sources (such as transformers, heaters).

4.2 Terminal Wiring Specification

Main circuit terminals:

Screw specifications: M3 (low power)/M3.5 (high power), tightening torque of 0.8N · m/1.0N · m respectively;

Wiring requirements: Connect the input (R/L1, S/L2, T/L3) to the power supply, and the output (U/T1, V/T2, W/T3) to the motor. Reverse connection is prohibited as it may damage the inverter;

Grounding terminal: It needs to be independently grounded with a wire diameter of ≥ 3.5mm ² (refer to section 10.1 wiring table).

Control circuit terminals:

Screw specifications: M2/M3, wire diameter 0.3-1.5mm ², sheath stripping length 5-6mm;

Wiring taboos: Control circuit and main circuit wiring should be separated (not parallel, not bundled, different conduit) to avoid interference.

4.3 Wiring precautions

It is prohibited to connect capacitive devices (such as noise filters and surge absorbers) on the output side, as this may cause a fire;

The length of the main circuit line is ≤ 30m, and if it exceeds this limit, the wire diameter needs to be increased (for example, for a 200V level 0.75kW motor, a wire length>30m requires a wire of ≥ 2.5mm ²);

When multiple inverters share a power supply, each one needs to be equipped with an independent MCCB (circuit breaker) to avoid the spread of faults.

Operation and monitoring

5.1 Operating Mode

Panel control: Set CMod=1, start with RUN key, stop with STOP key, adjust frequency with △/▽ key;

Terminal control: Set CMod to 0 and control operation by short circuiting the F-CC (forward rotation) and R-CC (reverse rotation) terminals;

Jog operation (JOG): Set the input terminal function to “JOG”, the motor runs at a fixed frequency of 5Hz when short circuited, and stops freely after disconnection;

Preset speed operation: By allocating SS1-SS4 terminals (a total of 4 terminals), 15 levels of preset speed can be achieved (F287-F294 parameters need to be set).

5.2 Status Monitoring

Monitoring content: The output frequency, load current (%/A), input voltage (DC), output voltage (%/V), cumulative running time (0.01=1 hour), etc. can be viewed through the “status monitoring mode” (press MON button twice);

Fault display: When tripped, the LED displays a fault code (such as “OC1” indicating acceleration overcurrent), and the FL relay operates (fault output);

Alarm message: Non trip warning (such as “rEr” indicating retry), only prompts not to stop the machine, and attention should be paid to the equipment status.

Servo amplifier: Only specify power, such as the power corresponding to “XXXX” in “BSDXXXX” (0100=100W).

Servo motor: format is “BSMXXXXXX”, where “XXXX”=power, “C”=shaft type (C=keyway, L=flat shaft), “N/B”=brake (N=none, B=present), “00/01″=option (00=none, 01=oil seal).

Installation requirements

1. Installation of servo motor

Project Requirements Remarks

Storage environment temperature -20 ° C~60 ° C, humidity 10% -90% RH (no condensation), the same requirement applies when equipped with gear heads

Working environment temperature -10 ° C~40 ° C, humidity 10% -90% RH (no condensation), temperature with gear head 0 ° C~40 ° C

The installation direction can be horizontal, downward, or upward (in accordance with IEC standards IMB5/L51, etc.), and the encoder end should not be subjected to force

Load limit radial load (127N-510N), axial load (19N-253N) refer to Table 2-5 in the document, such as BSM0100 radial 127N

Cable protection for mobile scenarios requires drag chains with a maximum bending radius to avoid oil/water immersion

Control power supply (all models) single-phase sL1, sL2 200-230VAC (-10%~+10%) 50/60Hz

2. Key wiring taboos

Do not connect the commercial power supply (200V) to the U/V/W terminals of the servo motor (as it may burn the motor).

Do not connect the grounding wire (E) to the U/V/W terminal, and do not connect the U/V/W terminal in reverse (which may cause fire/malfunction).

It is prohibited to conduct voltage withstand, megaohm, and buzzing tests on the encoder terminal (CN2) as it may damage the encoder.

The distance between the serial I/O (CN1) and the motor power cable should be ≥ 10cm (to avoid interference).

Test Run

1. Three stage testing process

Key inspection items for stage testing content

The first stage servo amplifier and motor are tested separately (not connected to the machine). 1. Power wiring (L1/L2/L3); 2. Motor power supply (U/V/W) and encoder wiring; 3. Motor rotation direction (parameter # 04); 4. No alarm

In the second stage, connect to the upper control system (not connected to the machine). 1. Connect the signal lines of the upper system; 2. I/O signals (such as emergency stop EMG, overtravel ± OT); 3. Motor speed/torque (in accordance with instructions)

The third stage of testing after installing the machine (final state): 1. The firmness of the motor installation; 2. Machine travel; 3. Servo parameter adjustment (refer to Chapter 6); 4. Positioning accuracy

2. Origin regression requirements

After power failure and restart, the motor needs to be rotated at a speed of ≤ 100r/min for 372 ° or more (approximately 1.04 rpm) in order to correctly detect the Z-phase.

Parameter settings

1. Parameter configuration method

Keyboard operation: Switch to “Parameter Editing Mode” (PnO) for settings through a 4-digit 7-segment LED display and 4 buttons (MODE/ESC, SHIFT, ENT, ∧/∨).

BSD Configurator: Connected to CN3 via LAN cable (CAT. 5 direct connection), supports parameter read/write, batch transfer, and monitoring.

2. Core parameter table

#02 instruction pulse compensation β position 1-32767 1 electronic gear ratio denominator

#03 Pulse train input form: Position 0 (command pulse+symbol), 1 (forward/reverse pulse), 2 (two signals with a 90 ° phase difference), 1 matches the output type of the upper system pulse

#04 Rotation direction switching/output pulse phase all 0-30 set motor forward rotation direction (CCW/CW) and output pulse phase

#05 tuning mode position/speed 0 (automatic), 1 (semi-automatic), 2 (manual) 0 select servo gain tuning mode

#06 Load inertia ratio position/velocity GYS: 0.0-100.0; GYG: 0.0-30.0 5.0 (BSM low power), 1.0 (BSM high power) ratio of motor inertia to load inertia

#07 Automatic tuning gain position/speed 1-20 10 Adjust servo response speed (high value, fast response but prone to vibration)

#09 Control mode switch all 0 (position), 1 (speed), 2 (torque), 3 (position) ↔ 0 fixed or switchable control mode for speed)

3. Parameter Effectiveness Rules

The parameters marked as “Power” (such as # 03, # 04, # 09) need to be powered off and restarted to take effect; Other parameters (such as # 01, # 02, # 07) take effect in real-time.

Servo adjustment and special functions

1. Tuning method

Operation points for applicable scenarios of tuning types

Automatic tuning (# 05=0) Most conventional mechanical amplifiers automatically estimate the inertia ratio and set the optimal gain

Semi automatic tuning (# 05=1) inaccurate estimation of inertia ratio, manual setting of # 06 (load inertia ratio) in scenarios, amplifier automatically calculates gain

Manual tuning (# 05=2) Automatic/semi-automatic tuning failed. Manually set # 40 (position gain), # 41 (speed response), # 42 (speed integration time), etc

2. Special adjustment function

Vibration suppression control: By setting parameters # 60- # 63 (anti resonance frequency 0-3), mechanical vibrations (such as end effector vibrations of robotic arms) are suppressed within a frequency range of 5.0-200.0Hz.

Instruction Follow Control: Parameter # 55 is set (0=none, 1=follow, 2=follow+stop compensation) to achieve zero deviation following of pulse instructions, suitable for high rigidity machinery.
