Inovance MD800 Series - Frequency Detection Range

Function Applications
-506-
F0-09 defines the running direction of the motor. You can change the rotation direction of the motor by
modifying this parameter without changing the motor wiring. Modifying this parameter is equivalent to
exchanging any two of the motor's U, V, W wires.
Note
After the parameter is initialized, the original rotation direction of the motor is resumed. Exercise cautions when us-
ing this function if motor rotation direction change is prohibited after system commissioning is complete.

When F8-14 is active, the motor runs at
zero frequency when a reverse run
command is input to the AC drive.
