Description

The Instrumentation Associates Triple Motor Controller is a compact microstepping motor controller/driver for 2/4 phase bipolar stepper motors. It can be used with or without incremental optical encoders and is equipped with 6 digital input lines and 6 programmable output lines that can be used for actuators (such as air-pad air-supply valves) or indicators (limit switch or run LEDs). The three motor controllers are implemented through a Galil microprocessor controller and independently addressed in software. Each motor is powered by its own independent driver amplifier.

Each of the controllers is equipped with 3 connectors on the back panel: Motor Power, Encoder and Limits-I/O. These can be configured as required for the particular application. In addition, the controller has a power entry module, an  RJ-45 ethernet connector and a DB9-F connector for serial connections to the host computer.

Tables of connector pin functions for are listed below. The stepper motor controllers are based on the Galil Motion Control DMC-2133 microcontroller which has a rich vocabulary of software commands for system configuration and operation. The software programming manual for the controller can be found here. 

The Triple Stepper Motor Controller is built to order and can be configured for your application.
