Retry wait time

Retry is a function that performs its own fault reset and restarts with pick-up. Is possible to
set the number of retries, and the wait time (t
is not possible after the programmed re-tries.
The retry is effective against power module (

If C21-0=0, retry will not function.
The FA-FC relay output will stay open during retry, but will not function.
OVT retry may not function correctly if the DC voltage drop is slow.
If the run command turns OFF during retry, the retry will be cancelled, and the
FA-FC relay contact will turn ON.
The pickup operation is not carried out during vector control with sensor (C30-0
