Description
Drop frequency at
instantaneous
power failure
Used to adjust the output frequency at power recovery from instantaneous
power failure.
•
At power recovery, the starting frequency is determined by subtracting
[Drop frequency at instantaneous power failure] from the output
frequency at instantaneous power failure.
•
If a power failure continues for a long period and the control circuit is
reset, the starting frequency at power recovery is 0.5 Hz, as in the case
of the ordinary power-up.
Free-run time at
instantaneous
power failure
Free-running time upon recovery from instantaneous power interruption
can be set.
■
Restart
prevention upon
power recovery
When set to
, continuous operation is inhibited even if power is
restored after instantaneous interruption.
Retry selection
Retry start time
These parameters will automatically try to cancel the trip and continue
operation after the specified retry start time. The number of retries is
initialized if the parameters have not been used for 120 minutes after the
previous retry.
■
(NO): no retry

If [

Relay output selection] is set to TRIP, no trip signal
is output during retry, until the retry is repeated to the set No. of times.

the retry function is disabled.
