The motor does not
rotate after the
frequency
converter is
running
The motor or the motor
connection cable is abnormal
Confirm that the connection
between the frequency converter
and the motor is correct
Incorrect setting of frequency
converter parameters
1. Restore the factory default,
reset the parameter group that
needs to be used.
2. Check the related parameters
of the motor and encoder, and set
them correctly
3. Check the frequency converter
model P0201.F and control mode
selection P0203.F, and set them
correctly
4. When using vector control
mode, motor parameter
identification needs to be
completed
5. In V/F mode, the torque boost
P1103.F parameter can be
adjusted appropriately
The connection cable between
the drive board and the control
board is in poor contact
Consult A-TS technical support
The drive board is faulty
5
DI terminal failure
The parameter setting is wrong
Check whether the digital input
module enable P2508.F is set to
1
There is an error in the external
wiring
Check whether the control board
wiring is good
24V power supply is abnormal
Check whether the DI input 24V
power supply is normal
IO expansion board failure
Consult A-TS technical support
Control board failure
6
DO terminal failure
The parameter setting is wrong
Check whether the digital output
module enable P2500.F is set to
1
There is an error in the external
wiring
Check whether the control board
wiring is good
IO expansion board failure
Consult A-TS technical support
Control board failure
7
Overcurrent or
overvoltage faults
are frequently
Improper parameter setting
1. Check the related parameters
of the motor and encoder, and set
them correctly
