SMSD‑4.2Modbus - programmable stepper motor controller

SMSD-4.2Modbus controller can act as a master or slave in an RS-485 Modbus network, capable of controlling external devices or receiving control commands from a PLC via the Modbus RTU/ASCII protocol. It also supports standalone operation according to a predefined user program. This controller offers microstepping options ranging from 1/1 to 1/256, and it includes a morphing function that enables a seamless transition from microstepping mode to full-step mode at a specified speed, ensuring torque is maintained at high speeds. Overheating protection is also integrated. These controllers can operate in real-time and are suitable for constructing both local automation units and distributed I/O systems, facilitating data exchange through the RS-485 interface with the Modbus protocol.
