A cost-effective solution for precise master/follower velocity control of AC and DC variable speed drives.

The MS320 is a cost-effective way to add digital PID velocity control to a master/follower variable speed drive system by monitoring a signal emanating from a feedback sensor “Digital or Analog” on a machine and fine-tuning the speed reference. The MS320 features three AC inputs: one dedicated for run/stop and two programmable for user-defined functions such as setpoints, jog, setpoint scroll, or stop. A unique feature of the MS320 is a programmable “reset maximum DAC RPM” variable for wind and unwind applications that maintains constant line speed as the core builds or unwinds.

An optional expansion board provides the user with two additional AC inputs, two relay outputs, RS422, and two analog inputs programmable for feedback signal, lead signal, master setpoint, follower setpoint, setpoint trim, or inverse setpoint trim.
