Software
The drive provides configuring motor control parameters via RS‑232. It is also possible to directly control the motor with commands from a PC or PLC. SMD‑mini‑control software is designated for quick parameterization of the drive, as well as for performing a given movement, setting speed and acceleration, starting and stopping the motor, turning on/off motor phases.
