Err25
Load becoming 0
The AC drive running current
is lower than F11.22
Check that the load is
disconnected or the setting
F11-22 and F11-23 is
correct.
Err26
With-wave
current limit fault
1: The load is too heavy or
locked rotor occurs on the
motor.
2: The AC drive model is of too
small power class.
1: Reduce the load and
check the motor and
mechanical condition.
2: Select an AC drive of
higher power class.
Err27
Inverter soft-start
relay is off
1: The grid voltage is too low
2: Rectifier module failure
1: Check the grid voltage
2: Demand for technical
support
Err28
Software version
compatibility fault
1: The upper and lower
transmission module

Instantaneous
overcurrent
1. Inverter output circuit being
grounded or short-circuit;
2. The acceleration and
deceleration time is too short;
3. Manually torque boost or
V/F curve not appropriate;
4. Voltage too low;
5. Start the running motor;
6. Sudden-load in the acce
process;
7. Model selection of inverter
power is too small.
1. Troubleshooting
peripheral problems;
2. To increase the
acceleration time;
3. Adjust the manually
torque boost or V/F curve;
4. Adjust the voltage to
normal range;
5. Select RPM track start or
start after motor stopped;
6. Cancel sudden-load;
7. Select the inverter with
larger power.
Err30
Instantaneous
overvoltage
1: Input voltage is too high;
2. There is external force drag
the motor to run in dece
process;
3. The deceleration time is too
short;
4. No installation of braking
resistor.
1: Adjust the voltage to
normal range;
2. Cancel external force or
install brake resistor;
3. To increase the
deceleration time;
4. Install braking resistor
