New Product: Multiphase stepper controller

The multiphase ICD200 stepper controller/driver is a stand-alone system designed to execute trapezoidal and S-curve shape (memorydata) acceleration/ deceleration motion profiles in both two and four-phase stepper motors.

Three operation modes are available: Sensor mode, absolute position mode, and relative position mode. The unit is rated at 1.2 A/phase for unipolar stepper motors and 0.6 A/phase for bipolar motors. Input power is 24 Vdc with power consumption of 36 W. This single-axis integrated system provides 20,000 steps/rev microstepping resolution. An onboard potentiometer lets users easily adjust driver running currents. Up to 15 devices can be daisychained using the RS-485 communication protocol. Input/output interface functions include: Photocoupler inputs, point starting code bits, home search start, immediate stop and direction of rotation, current off, and an alarm output sensor interface option.
