VFD-F Series

When Pr. 11-01 is set to 02 “Fixed Amount Circulation” and adding relay card “RY-00”, VFD-F is able to drive 4 motors under PID control mode by turns.

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 switch 1st motor power supply to commercial power and energize 2nd motor. At this time, 1st motor is full power running and 2nd motor is running PID control mode by VFD-F.

Previous routine repeats to 2nd motor→3rd motor→4th motor till VFD-F reaches proper PID values. VFD-F only runs PID control mode to last motor, others run full power.
