Fault code Fault type Possible fault cause Solutions
Er.CoP
Operation
panel
parameter
copying error
The operation panel parameters are
incomplete or the operation panel
version is inconsistent with main control
panel version.
Refresh the operation panel data and version, use
P00.06=1 for uploading the parameters first and
then use P00.06=2 or 3 for downloading.
The operation panel EEPROM is
damaged.
Seek for service support
Er.TUn
Poor
auto-tuning
The nameplate parameters of the motor
are incorrect.
Set the parameters properly according to the motor
nameplate
When reverse running is prohibited,
reverse rotating auto-tuning is
performed.
Cancel the reverse running prohibition
Auto-tuning overtime
Check motor wiring
Check the P02.16 (upper limit frequency) and
see whether the P02.17 set value is lower than rated
frequency.
Er.PG1 PG fault
With PG vector control (or with PG V/F
control), the encoder signal disconnects.
Check the encoder wiring and rewiring
Er.PST
Parameter
setting error
Wrong speed feedback encoder
selection setting
The same speed feedback encoder shall not be
used for two motors simultaneously.
Wrong analog AI function selection
setting
The same function shall not be selected for different
analogs simultaneously.
Process closed loop invocation setting
error
During vector control, the torque limit (P05.13，
P05.14) and frequency reference (P02.04 or PLC
section frequency reference) can not be given by
the process closed loop simultaneously.
Er.24v
Control board
24V power
short circuit
Short circuit of P24 and terminal COM
Confirm whether the wiring of P24 and COM is
correct
The interface board circuit is damaged.
Replace the interface board, seek for service
support
Er.oPT
Expansion card
fault
The expansion card is poorly inserted. Reinsert the expansion card
The expansion card is damaged. Seek for service support
Er.GdF
Grounding
short circuit
fault
One of the phases (The most likely one
is phase U) is grounding short circuited.
Check the grounding short circuit of the output three
phase and troubleshoot it.
