Pr. 65 “retry selection”, Pr. 67 “number of retries at alarm
occurrence”, Pr. 68 “retry waiting time”, Pr. 69 “retry count
display erasure”
• When an error occurs in the high power factor converter, the retry
function allows it to reset the alarm automatically and continue
operation.
(1) With Pr. 65 “retry selection”, you can limit the high power factor
converter errors reset for retry.
(2) With Pr. 67 “number of retries at alarm occurrence”, you can set
the number of retries to be made when a high power factor
converter error occurs.
(3) With Pr. 68 “retry waiting time”, waiting time from when a high
power factor converter error occurs until a restart is made can
be set in the range 0.1 to 360s.
(4) By reading the value of Pr. 69 “retry count display”, the
cumulative number of restart times successfully made by retry is
provided. The set value of “0” erases this cumulative number of
times.
Pr.65 Alarms Reset for Retry
0No retry
1 Overcurrent shut-off (OCT)
2 Power supply fault (IPF) (Note 4)
3
Overcurrent shut-off (OCT),
power supply fault (IPF)
Pr.67 Setting Number of Retres Alarm Signal Output
0 (factory setting) Retry is not made. –
1 to 10 1 to 10 times Not output
101 to 110 1 to 10 times Output.
Note: 1.The high power factor converter automatically starts
operation after the time set in Pr. 68 “retry waiting time” has
elapsed. Exercise care not to jeopardize the operator.
2.The cumulative number in Pr. 69 “retry count display
erasure” is incremented by “1” when retry operation is
regarded as successful, i.e. when normal operation is
continued without any alarm occurring during a period four
times longer than the time set in Pr. 68 “retry waiting time”.
3.If alarms occur successively during a period four times
longer than the above waiting time set in Pr. 68, the screen
display of the parameter unit will be different from the
display provided when the first retry is made. (Option fault
“E.OPT”) Note that the error reset for retry is not stored.
4.With 2 set in Pr. 65 “retry selection” (power supply fault),
the IPF signal is detected when a power supply fault
occurs.
CAUTION
When you have selected the retry function, stay away from
the motor and machine. They will start suddenly (after a
given time has elapsed) when an alarm occurs. When you
have selected the retry function, apply the supplied
CAUTION labels to easily identifiable positions.
