Tab. 6-27: Faults selected for retry
NOTES
When terminal assignment is changed using Pr. 190, Pr. 192 and Pr. 197, the other func-
tions may be affected. Make setting after confirming the function of each terminal.
For a retry error, only the description of the first alarm is stored.
When an inverter alarm is reset by the retry function at the retry time, the accumulated data
of the electronic thermal relay function, regeneration converter 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.
b
CAUTION:
When you have selected the retry function, stay away from the motor and machine
unless required. They will start suddenly (after the reset time has elapsed) after
occurrence of an alarm.
When you have selected the retry function, apply CAUTION seals in easily visible
places.
