frequency
converter
2. Check the frequency converter
model P0201.F and control mode
selection
3. When using vector control
mode, motor parameter
identification needs to be
completed
Improper setting of acceleration
and deceleration time
Set acceleration time P1602.F
and deceleration time P1603.F to
appropriate values
Load fluctuation
Consult A-TS technical support
The models of the motor and the
frequency converter do not match

Closed loop, motor
speed cannot be
increased
Encoder parameter setting is
improper
Set the encoder parameters
correctly
Encoder failure, wrong
connection or bad connection of
encoder wire
Replace the encoder (code disc)
and reconfirm the wiring
Drive board failure
Consult A-TS technical support
Encoder board failure

After power on, the
contactor is
reported to be
abnormal
The contactor is not closed

During the
acceleration and
deceleration of the
frequency
converter, the
motor speed is
constant. That is,
the actual
acceleration and
deceleration time is
greater than the set
acceleration and
deceleration time
Overvoltage speed out of control
protection takes effective
Change parameter P4924.F
overvoltage speed out of control
protection to 0: disable, turn off
the protection function or adjust
parameter P4925.F overvoltage
speed out of control point
appropriately
Overcurrent speed out of control
protection takes effective
Properly adjust the parameters
P4926.F overcurrent speed out of
control point 1 and P4927.F
overcurrent speed out of control
point 2
