or No Load RPM, coil A current ramps

down to 0, and then coil B current ramps up

to the Reverse Set- point.

 The module will try to restart normal

operation after the reverse cycle completes.

Reverse Time (0 to 65 Sec)  It sets the time that coil B will remain in reverse during an Auto-Reverse cycle.

Reverse Retry Count (0 to 65535) The number of times the Auto-Reverse cycle will try to restore normal RPM

before declaring a fault and disabling the unit.

Reverse set-point (0 to 100%)  The percentage of Imax output current for coil B during the reverse cycle.

Fixed set-point (0 to 100%)

 The percentage of Imax output current for coil A when the measured RPM is above the RPM slow or Max Load
