LMD17 Electric Cylinder NEMA 17 CANopen with M12 Connectors

Liberty* MDrive® (LMD) CANopen NEMA 17 (42 mm) with eCylinder integrates a 1.8° 2-phase stepper motor, drive electronics, and inline mounted captive electric cylinder. Linear motion is produced by an ACME screw/nut system coupled directly to the driving shaft. These compact products offer many distinct benefits including competitive price, high accuracy and repeatability. A cleaner, quieter alternative to pneumatics for some applications. Feedback options include: Open loop stepper, closed loop with hmTechnology (hMT) or multi-turn absolute encoder.

M12 circular connector interface for power, I/O and communications. CiA303-1 compliant M12 for connection to a CAN bus 2.0b active network.

This product communicates over CANopen and supports the following CAN in Automation (CiA) standards:

CiA301: Application layer and communications profile
CiA402: Device profile for drives and motion control
CiA305: Layer setting services
CiA303-1: Cabling and connector pin assignment
