Er01-0
IGBT fault
The actual output current
exceeds the specified value
1.Drive fault (drive circuit, IGBT
fault);
2.Short circuit of motor cable U,
V, W, or the motor cable is
grounded or connected
improperly;
3. Motor burn down;
4. Reverse sequence of U, V, W
phase;
5. Parameters are inappropriate
and cause system divergence.
6. ACC/DEC of start/stop process
is too short;
7. Instantaneous load is too large.
1. Remove the motor cables and
enable the drive, if the fault persists,
replace the drive;
2.Check the motor cables and wiring
3.Reduce the value of P0.10 and
P0.11;
4.Comission the loop parameters to
stabilize the system and reduce the
value of P0.12;
5.Increase the ACC/DEC time;
6.Replace with the drive with larger
power;
7. Replace the motor.
Er01-1
Brake tube fault (7.5kW
and above models)
Brake unit fault
Replace the drive
Er02-0
Encoder fault– The
encoder cable broken
1. The encoder is not connected;
2. The encoder connector
becomes loose;
3.One of U, V, W, A, B Z phase
cables is broken;
4. Reversed A/B phase of the
encoder;
5. Communication break or
abnormal data caused by noise;
6.Normal encoder communication
but abnormal communication
data;
7. FPGA communication overtime
8. The drive does not support the
encoder type.
1. Check the encoder connector or
replace the encoder cable if the
cable is disconnected;
2. Detect whether encoder power
voltage is normal;
3. Reduce the interference of the
encoder, route the encoder and
motor independently and connect
the shielded cables of the encoder to
FG;
4. If reporting encoder disconnection
fault when power on, check whether
the available drive encoder type is
consistent with the available motor
encoder type according to P0.01.
