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

points. The 4.3 and 7.2 amp servo 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.

The S2K Series stepper controller requires a single-phase 115 VAC supply. S2K Series

servo controller models rated 230 VAC and 4.3 or 7.2 amp can operate on either 115 VAC

single-phase or 230 VAC three-phase, while the all other models are rated for three-phase

input. The 230 and 460 VAC models are intended to be operated from a three-phase

supply but can be used with a single-phase power source.
