Microstepping motor controller OMD34b

DCcompactintegrated

The OMD34b is a new and improved version of the original OMD34, advanced microstepping motor drive for bipolar stepper motors. Like the previous version this new drive is capable of microstepping from half steps up to 256 microsteps per step. Improvements include 4x the maximum step rate, smaller size, up to 3.5 Amp phase current without a heat-sink. The new small size (2.22" x 2.22") comes mounted on a flat heat-sink plate though the OMD34b can be mounted directly to a size 23 motor and supports a center pass-through hole for motor shaft of dual-shaft or linear actuator motors. Features: Micro-Step resolution from full to 1/256 microsteps Bi-polar chopper drive Single +18V to +80V motor supply input Up to 7 Amp phase current for high torque motors Resolution and phase current selectable via dip switch Electrically isolated control signals Easy wiring with screw-terminal connectors Compact, measuring only 2.22" x 2.22" x 1.4"
