PG-F3 power supply circuit isdamaged. Replace the option.
Digital Operator Display Fault NameoS Overspeed
The motor speed feedback exceeded the F1-08 setting.
Cause Possible Solution
Overshoot is occurring. Increase the settings for C5-01 (Speed Control Proportional Gain 1) and reduce
C5-02 (Speed Control Integral Time 1).
Incorrect speed feedback scaling
when terminal RP is used as speed feedback input in V/f
control.
• Set H6-02 to the value of the speed feedback signal frequency when the motor runs at the maximum speed.
• Adjust the input signal using parameters H6-03 through H6-05. Incorrect PG encoder pulse
number set. Check and correct parameter F1-01.
Inappropriate parameter settings. Check the setting for the overspeed detection level and the overspeed detection time (F1-08 and F1-09).
Digital Operator Display Fault Name PGo
PG Encoder Disconnected
Detected when no PG encoder pulses have been received for a time longer than is
set to F1-14. Cause Possible Solution
PG encoder cable is disconnected. Reconnect the cable.
PG encoder wiring is incorrect. Correct the wiring.
PG encoder does not have enough power. Make sure the correct power supply is properly connected to the PG encoder.
Brake control sequence is incorrect. Correct the brake control sequence and verify that the brake has been released.
Digital Operator Display Fault Name PGoH
PG Encoder Hardware Fault
PG encoder cable is disconnected.
Cause Possible Solution
PG encoder cable is disconnected. Reconnect the cable.

WARNING!

Ensure the drive RUN circuit is locked out and a RUN command is not possible before attempting to manually rotate the motor shaft with the drive powered on. Failure to comply may cause injury
to personnel due to inadvertant equipment movement.
Reverse motor rotation is indicated by a negative value for U1-05; forward motor rotation is indicated by a positive value.
If the motor is rotating forward, but U1-05 reads that it is rotating in reverse, switch the rotation direction for the PG1 encoder by setting parameter F1-05 to 1.
Note: If the drive is initialized using A1-03 = 1110, 2220, or 3330, the value for F1-05 will reset to the factory default and the parameter will need to be readjusted to switch the direction.
