4 or 8 Axis Open Loop Stepper Drive Module

The SDMnt is designed to address the needs of OEMs with machines employing many open loop stepper motors. Controllable by any ACS SPiiPlus Platform EtherCAT master, it provides 4 or 8 axes of stepper drives up to 3A per axis. One of the axes is a bipolar stepper drive, while the remaining 3 or 7 axes are unipolar stepper drives. An optional built-in 40Vdc motor power supply offers added integration.
