H04, H05
Retry (No. of retries, Latency time)
To automatically exit from the alarm status and restart the inverter, use the retry
functions. The inverter automatically exits from Alarm mode and restarts without
issuing a block alarm even if it has entered the forced Alarm mode. If the inverter
has entered Alarm mode many times in excess of the number of times specified
by function code H04, it issues a block alarm and does not exit Alarm mode for
restarting.
Listed below are the recoverable alarm statuses of the inverter.
Alarm status
Instantaneous overcur-
rent protection
Overvoltage protection OU1, OU2 or OU3 Motor overloaded
Heat sink overheated
Motor overheated
No. of retry times (H04)
Set the number of retry times for automatic exit from Alarm mode. If the inverter
has entered Alarm mode during the retry times specified, the inverter issues a
block alarm and will not exit from Alarm mode for restarting.
If the retry function has been activated, the inverter will automatically restart when
the power is recovered, according to some tripping causes. Design the machine so
that human body and peripheral equipment safety is ensured even after automatic
restarting.
Otherwise an accident could occur.
