The NEMA 23, 1.8-degree bipolar step motor has an integrated controller and delivers up to 294 oz-inch of holding torque. The unit has an input voltage range from 12 to 40V dc, phase current range from 0.3 to 3.0A peak, and microstepping capabilities of 2, 4, 8, 16, 32, 64, 128, and 256x. With its integrated controller, the 23CE provides stand-alone operation without connecting to a PC. Four Kbytes of memory store up to 16 different programs. The unit has two dedicated inputs: one for an optical sensor for homing and another for switch closure to ground. Programmable items include four user-configurable digital I/O's, software-selectable hold and move currents, and fully-programmable ramps and speeds. System-level enhancements come from an optional converter card for RS485 communication and the integrated encoder with position correction capabilities that operates up to 1,250 cycles per revolution (CPR).
