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
parameters in the parameter
version of the control panel
version mismatch.

Err29
Hardware
overcurrent
1: The acceleration and
deceleration time is too short
2: The motor parameters are
not accurate
3: The drive hardware failure
1: To extend the
deceleration time
2: Set the correct motor
parameters
3: The demand for technical
support
Err30
Hardware
overvoltage
1: The deceleration time is too
short
2: Do not install braking
resistor
3: The drive hardware failure
1: To extend the
deceleration time
2: The installation of a
braking resistor
3: The demand for technical
support
