Cause
The PG signal cable is not
connected or cut off
PG card screw is loose
Malfunction caused by interference
Hardware failure
Encoder wiring is too long, causing
large voltage drop of PG card VP
power.

Cause
The drive operates in the low
frequency range (High HP: below
15 Hz; Low HP: below 5 Hz) and
IGBT temperature (High HP: 20°C;
Low HP: 50°C)
Fault Name
PG UVW line off
UVW line off for protection when using PG02U
(UvoF)

Check the PG signal cable
Tighten all the screws
Verify the wiring/grounding of the main circuit, control circuit and encoder to
prevent interference.
1. After you check the wiring, if AboF fault still exists after cycle the power,
return to the factory for repair.
2. Check if the VP power of PG card has no output, or the output voltage level
is abnormal.
3. Check if the encoder is broken.
1. Decrease the wiring length.
2. Power on the encoder by other power sources.

1. Reduce the ambient temperature of the operating drive.
2. Replace the drive with a larger power model.
3. Reset drive parameters or decrease carrier frequency.
4. If the drive operates in V/F control mode, reduce the output voltage for
low-frequency operation.
5. If the drive operates in IMVF and PMSVC control mode, decrease the
torque compensation gain (Pr.07-26).
