Fault Name
Hardware error of PG
Hardware error of PG card
card (PGF5)
Action and Reset
1. The PG card (PG01U/PG02U) can only be used with the permanent
magnetic motor. When the power is ON and Pr. 00-04=29 pole section
shows 0 or 7 (wiring error or no U/V/W signal input), the PGF5 error will be
activated.
2. The drive receives the operation command right after the power is ON,
meanwhile, the PG card is not ready yet.
Immediately act
N/A
Manual reset
Reset after cycle the power.
Yes
Re-connect the cables correctly
Verify if it is the UVW encoder
Choose the correct setting of Pr. 10-00
Check if it is the UVW encoder or Delta encoder
Install the correct PG card
Fault Name
Reverse direction of
Rotating direction is different from the commanding

direction detected by the sensorless
(SdRv)
Action and Reset
Software detection
Pr. 10-09
Pr. 10-08
0: Warn and keep operation
1: Warn and ramp to stop
2: Warn and coast to stop
Manual reset
Immediately reset
When Pr. 10-08=1 or 2, SdRv is a "Fault", and the fault is recorded.
Decrease the setting of Pr. 10-25
Reset the motor parameter and execute parameter tuning
Check if the cable is well functioned or replace the cable
Start speed tracking function (Pr. 07-12)
Verify the wiring of the control circuit and wiring/grounding of the main circuit to
prevent interference.
