Delta Electronics VFD-F Series manual 5-66

VFD-F Series

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.

When 1st and 2nd motors are running, 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 3rd motor as full power running and 1st motor is still running PID control mode by VFD-F. At this time, 2nd and 3rd motors are full power running.

Previous routine repeats to 3rd motor→4th motor→5th motor till VFD-F reaches proper PID values. VFD-F only runs PID control mode to 1st motor, others run full power.

When this parameter isn’t set to 00, 03-00 to 03-07 multi-function terminals will automatically set the corresponding output motor.
