Contact for technical support
Err25
Load becoming 0
The AC drive running current
is lower than E0.22
Check that the load is
disconnected or the setting
E0-22 and E0-23 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
parameters in the parameter
version of the control panel
version mismatch.

Err29
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
acceleration 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
higher rating.
Err30
Instantaneous
overvoltage
1: Input voltage is too high;
2: There is external force drag
the motor to run in
deceleration 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
Err39
Motor
temperature too
high
1: PTC sensor configuration
not right
2: Motor temperature
protection value too small
3: Motor temperature too high
1: Reset PTC sensor
parameter
2: Increase motor
temperature protection value
3: Wait until motor is cooled
Err40
The set running
time ends
1: Running time more than
A0.25
1: Contact the dealer
Err41
Overload warning
1: when E0.18 = 00100 and
the current output amp is more
than E0.19
1: Check the current load
A33
Pre-warning of
Weak Light
Output frequency is lower than
or equal with lower limit of PI
output frequency, and has
continued under this state for
a duration greater than delay
time of weak light.
Check the lower limit of PI
output frequency and
weak-light delay the set
value
