11-10
Condition: deviation from the Speed command and the feedback speed
exceeds the allowable range (P2.034).
Causes:
1. A drastic change in speed.
2. Incorrect setting for P2.034.
1. Use the signal detector to check if the input analog voltage signal is
normal. If not, adjust the signal changing rate or enable the filter
function.
2. Check and make sure the value of P2.034 (over-speed warning) is
correct.
DI.ARST
Condition: the input frequency for 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
frequency. Correctly set the input pulse frequency.
DI.ARST
Condition: Deviation of position command and feedback exceeds the
allowable range (P2.035).
Causes:
1. The maximum position deviation is set too low.
2. Gain value is set too low.
3. Torque limit is set too low.
4. Excessive external load.
5. Improper setting for the E-gear ratio.
1. Check the value of the maximum deviation (P2.035 excessive position
deviation warning condition).
2. Check if the gain value is appropriate for the application.
3. Check if the torque limit setting is appropriate for the application.
4. Check the external load. Reduce the external load or re-evaluate the
motor capacity if necessary.
