SV-DA200 series AC servo drive Faults and solutions
-257-
3. Shield the fault by P4.98, and then
carry out corresponding initialization
to the motor parameters.
Current sensor fault–U
phase current sensor
fault
1. Current sensor or abnormal
detection circuit;
2. Power on when the motor shaft
is in a state of non-stationary.
Repower on when the motor is in
static state or change the drive
Current sensor fault–V
phase current sensor
fault
Current sensor fault–W
phase current sensor
fault
System initialization fault
The self-inspection is not passed
after initialization.
1. Repower on;
2. If the fault occurs for several
times, change the drive.
Setting fault– Motor
model does not exist
1. Ensure the motor model is set
correctly;
2. Ensure the motor parameter
model matches with the power class
of the drive.
Setting fault–Motor and
drive model does not
match
Setting fault– Software
limit setting error
Software limit values setting is
improper.
The setting value of P0.35 is less
than or equal to the setting value
of P0.36.
Setting fault–return to
homing mode setting
fault
Mode of P5.10 is set incorrectly.
Set P5.10 according to the
instructions.
Setting fault– Point
control travel overflow
fault
The signal increment of idle travel
of the bit exceeds 2
31
-1.
The single travel cannot exceed
2
31
-1 in the absolute position mode
Regeneration of
discharge overload fault
1. The power of the built-in
braking resistor is relatively low;
2.The motor speed is too high or
the deceleration is too fast;
3. The action limit of the external
braking resistor is restricted to
10% of the duty ratio.
1. Replace with an external braking
resistor and increase the power;
2.Modify the deceleration time and
reduce regeneration discharge
action rate;
3. Reduce the motor speed;
4. Improve the capacity of the motor
and drive.
