AL009 Excessive deviation of Position command
Trigger condition
and cause
Condition: difference between the command speed and the feedback speed
exceeds the allowable range set by P2.034.
Cause:
A drastic change in the input Speed command.
1.
Improper setting of P2.034 (Excessive deviation warning condition of Speed
2.
command).
Incorrect wiring of the UVW and encoder cables.
3.
Use the signal detector to check if the input analog voltage signal is normal.
1.
If not, adjust the rate of change for input signals or enable the filter function.
Check if the value of P2.034 (Excessive deviation warning condition of Speed
2.
command) is set properly.
Check if the wiring of the motor power cable and encoder cable is correct.
3.
DI.ARST
Condition: the input frequency of the pulse command is over the allowable value
for the hardware interface.
Cause: the pulse command frequency is higher than the rated input frequency.
Use the scope to check if the input frequency is higher than the rated input
frequency and correctly set the input pulse frequency.
DI.ARST
Condition: difference between the command position and the feedback position
exceeds the allowable range set by P2.035.
Cause:
The maximum position deviation is set too low.
1.
Gain value is set too low.
2.
Torque limit or speed limit is set too low.
3.
Excessive external load.
4.
Improper setting for the E-Gear ratio.
5.
The power cable is loose.
6.
The maximum speed limit is set too low.
