Equipment Overview

The FANUC S2K series is a high-performance standalone brushless servo or stepper amplifier series that integrates motion controllers and user configurable I/O functionality. The controller can be configured with a rotary transformer or a serial encoder motor feedback model. The encoder based S2K servo model can only be used in conjunction with GE Fanuc S series (SLM, SDM, or SGM) servo motors. The S2K rotary transformer feedback servo controller uses GE Fanuc MTR series (3N, 3S, or 3T) servo motors or third-party motors with appropriate ratings and rotary transformer specifications.

The servo model supports continuous stall torque of 0.84-478 in lb (0.095-54 Nm), while the stepper model supports holding torque of 144-3074 oz in (16.3-21.7 Nm). The servo controller model includes four 230 VAC ratings of 4.3, 7.2, 16, and 28 ampere continuous, as well as two 460 VAC ratings of 7.2 and 20 ampere continuous (the 460 VAC model only provides feedback for the rotary transformer). The peak current of the 230 VAC servo model is twice the continuous rated value, while the 460 VAC servo model is 1.5 times the continuous rated value. The rated value of the stepper controller is 5 amperes.

Support DeviceNet ™  The PROFIBUS communication model includes 14 discrete I/O points. 4.3 and 7.2 ampere servo models and stepper models can also provide 21 I/O points instead of DeviceNet or PROFIBUS communication. All drivers are capable of supporting Modbus/RTU protocol. If the optional Modbus adapter (product number IC800MBUSADP) is used, the standard RS-232 serial port can be used for multi-point applications. This adapter is an externally installed multi-point RS-232 to RS-485 serial port converter.

The S2K series controller is optimized for use with GE Fanuc S series or MTR series servo and stepper motors. If the motor and amplifier are not properly matched, overload and possible component damage may occur. Tables 1-1 to 1-3 show the recommended pairing of components.

The S2K series stepper controller requires a single-phase 115 VAC power supply. The S2K series servo controller models rated at 230 VAC and 4.3 or 7.2 amperes can operate on 115 VAC single-phase or 230 VAC three-phase, while all other models are rated for three-phase input. The 230 and 460 VAC models are designed to operate from three-phase power sources, but can be used with single-phase power sources.

The S series servo motors optimized for the S2K series controller range from 30 W to 5 kW and are rated at 230 VAC to achieve full speed. Using a 115 VAC power supply will result in a reduced operating speed of approximately half of the rated speed.

The 30 to 1000 watt S series servo motors (SLM models only), MTR-3S and MTR-3N series, and all stepper motor models are designed with standard NEMA shaft and flange mounting configurations for easy installation onto existing gear reducers and couplings. The 750 watt S series motor is installed with a super large shaft diameter (0.625 inches) for NEMA 34 to handle the peak torque rating of this model. The S series motor models ranging from 1 to 5 kW (except for the SLM100 1kW motor) and all MTR-3T series motors have metric installation configurations.

All servo motors can be equipped with an optional 24 VDC holding brake. These brakes are spring set, electrically released models designed to maintain static loads. The user must provide a separate 24 VDC brake power supply. The 30-750 watt S series motor has a pigtail cable with a box type connector for connecting the motor power supply, encoder, and brake. The 1000 to 5000 watt S series motors have MS style connectors, and the brake power supply (if needed) is integrated with the motor power supply in a common connector/cable. The MTR series servo motors include MS type connectors for brake power input. The MTR-3N and MTR-3T series brake motors integrate the brake power supply and motor power supply into the same cable. The MTR-3S brake motor requires a separate brake power cable (CBL-30-BT).

The S2K series controller is configured and programmed using Motion Developer software on a personal computer. This software is an independent application that works in the Machine Edition software environment, providing tools for beginners to simplify programming and direct code input for advanced users.

Contains curves for MTR series stepper motors/controllers, S-series servo motors/controllers, and MTR series servo motors/controllers, demonstrating the relationship between motor speed and output torque. The motor can operate continuously at any speed and torque combination within a specified continuous operating range.

Servo motor derating based on ambient temperature

The S series motor generates continuous torque as shown in the speed/torque curve (Section 2.2.2) within a certain ambient temperature limit, depending on the motor model. The following curve describes the continuous torque derating required for operation at ambient temperatures above this rated value and up to a limit of 40oC. The intermittent torque available for each motor does not require derating.

The MTR series servo motors are rated at an ambient temperature of 25oC and are mounted on 10 “x 10” x 0.25 “aluminum heat sinks. For motors operating at higher ambient temperatures, the continuous torque of the motor must be reduced as follows: continuous torque at ambient temperature, toC=rated continuous torque x (155-t)/130.

Adequate precautions shall be taken when installing the motor to ensure proper protection from excessive liquid and spray exposure.

Servo motor maintains brake

The servo motor can be equipped with an optional integrated parking brake. The brake is designed for fail safe operation and must be powered by a 24 Vdc power supply to release the brake.

NEMA motor installation

The MTR series and S series motors have installation configurations as shown in the table below. For dimensional information about these motors (including installation dimensions), please refer to the mechanical drawings in Chapter 3.

The MTR series stepper motors have standard NEMA shaft and flange installation configurations, as shown in Table 2-17 below. For the size information of these motors, please refer to the mechanical drawings in Chapter 3.

S series servo motor vibration test

These motors have two types of vibration tests, namely scanning test and resonance point test.

Scanning test: The motor undergoes a 5G variable frequency test on each of the three axes (X, Y, Z) for eight hours. For the purpose of these tests, the X-axis is parallel to the motor axis, the Y-axis is parallel to the encoder connector, and the Z-axis is at a 90 degree angle to X and Y. In this test, the vibration frequency increased from 20 to 3000 Hz within two minutes, and then decreased from 3000 to 20 Hz within two minutes. This pattern was repeated for eight hours.

Resonance point test: Firstly, identify the resonance frequency with the highest vibration when testing the motor in three directions (X, Y, Z) at a variable frequency of 5 G (20 to 3000 Hz). Then, the motor vibrates 10 million times in each direction (X, Y, Z) at the identified resonance frequency.
