FD-F
When Pr. 11-01 is set to 03 “Fixed Amount Control” and adding relay card “RY-00”, VFD-F is able
to drive 1 motor under PID control mode and another 4 motors as full power running.
System powers up, VFD-F drives 1st motor as PID control mode. If VFD-F output frequency
continually surpasses 11-06 frequency setting and 11-05 time period, after time lag of 11-04, VFD-F
will energize 2nd motor as full power running and 1st motor is still running PID control mode by
VFD-F.
