 During a retry, the Y64 signal is ON. For the Y64 signal, assign the function by setting "64 (positive operation)" or "164
(negative operation)" to Pr. 190 or Pr. 192 (output terminal function selection) .
 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 298 for the fault description.)

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 and 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 an inverter 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.
 The retry function is invalid for the fault initiated by the fault initiation function.
When you have selected the retry function, stay away from the motor and machine in the case of the inverter is
tripped. The motor and machine will start suddenly (after the reset time has elapsed) after the inverter trip.
When you have selected the retry function, apply in easily visible places the CAUTION stickers supplied to the
Instruction Manual (Basic).
