SDMWx170 Stepping Motor Full Digital Programmable Drive The SDMWx170 module is a compact step motor drive for wall installations. The controller integrates a microstep drive and a logic able to move to some default positionings following precision trajectories according to position and speed commands mastered by a PLC. The communication to a PLC or industrial PC is made through a CANbus or a RS232/485 link. The drive has #4 5 –:- 24 Vdc inputs, #1 analog ±10 V input and #4 24 Vdc outputs. All digital inputs and outputs are optoisolated. Dip-switches are available for user settings and for the identification of the unit in a CANbus net. The system can be provided with additional #4 digital inputs, #4 outputs, #1 analog input and RS232/485 or CANbus link. The device can drive the stepper motor in open or closed velocity & position loops, according to internal acceleration and deceleration ramps, while runnig a real time checking of the critical working parameters as temperature rise, voltages and currents. The basic system is powered through a DC voltage bus and the version with AC inputs is provided with AC to DC supply voltage rectifier with EMI filter.
