Operation setting at fault occurrence
4
PARAMETERS
Using Pr.65, you can select the fault that will cause a retry to be executed. No retry will be made for the fault not indicated.
(Refer to page 268 for the fault description.)
indicates the faults selected for retry.
NOTE
Use the retry function only when the operation can be resumed after resetting a protective function activation.
Making a retry against the protective function, which is activated by an unknown condition, will lead the drive unit
and motor to be faulty. Identify in what condition the protective function was activated, and eliminate such condition
before resuming the operation.
When terminal assignment is changed using Pr.190 to Pr.192, the other functions may be affected. Set parameters after
confirming the function of each terminal.
The data stored as the error reset for retry is only that of the fault which occurred the first time.
When a drive unit fault is reset by the retry function at the retry time, the accumulated data of the electronic thermal
relay function, regeneration brake duty etc. are not cleared. (Different from the power-ON reset.)
Retry is not performed if E.PE (Parameter storage device fault) occurred at power ON.
If a fault that is not selected for a retry occurs during retry operation (retry waiting time), the retry operation stops
while the fault indication is still displayed.
Under position control, the retry function is disabled.
CAUTION
When you have selected the retry function, stay away from the motor and machine when the drive unit is
tripped. They will start suddenly (after the reset time has elapsed) after the drive unit trip.
When you have selected the retry function, apply in easily visible places the CAUTION stickers supplied.
