System Overview

The S2K Series is a family of high performance standalone brushless servo or stepper

amplifiers with integrated motion controllers and user configurable I/O functions.

Controllers are available in models configured for either resolver or serial encoder motor

feedback. Encoder-based S2K servo models can be used only with GE Fanuc S-Series

(SLM, SDM or SGM) servo motors. S2K resolver feedback servo controllers use GE

Fanuc MTR-Series (3N, 3S or 3T) servo motors or third-party motors with appropriate

ratings and resolver specifications. Please consult the factory for assistance in controlling non-GE Fanuc motors.

Servo models support continuous stall torque from 0.84–478 in-lb (0.095–54 Nm) while

the stepper model supports holding torque from 144–3.074 oz-in (16.3–21.7 Nm). Servo

controller models include four 230 VAC ratings of 4.3. 7.2. 16. and 28 amps continuous

and two 460 VAC ratings of 7.2 and 20 amps continuous (460 VAC models are only

available with resolver feedback). Peak currents of the 230 VAC servo models are two

times the continuous ratings while the 460 VAC servo models are 1.5 times the

continuous rating. The stepper controller has a rating of 5 amps.

Models supporting DeviceNet™ or PROFIBUS communications include 14 discrete I/O

points. The 4.3 and 7.2 amp servo www.abb-drive.com models and the stepper model are also available with

21 I/O points instead of the DeviceNet or PROFIBUS communications. All drives are

capable of supporting the Modbus/RTU protocol. If the optional Modbus adapter is used

(catalog number IC800MBUSADP) the standard RS-232 serial port can be used for

multidrop applications. This adaptor is an externally mounted multi-drop RS-232 to RS485 serial port converter.

The S2K Series controllers are optimized for use with the GE Fanuc S-Series or MTRseries servo and stepping motors.

Overload and possible component damage may occur

if the motor and amplifier are not properly matched. Tables 1-1 to 1-3 show the

recommended pairing of the components.
