Zero current
detection time
When the output current is at or below the zero
current detection level (Pr. 50) for longer than this
period (Pr. 51), the zero current detection signal
(Y13) is output.

Restart cushion
time
At power restoration after an instantaneous
power failure, you can restart the inverter without
the motor being stopped (with the motor
coasting).
The inverter begins to restart after this period
(Pr. 57) has elapsed after power restoration.
The inverter does not restart by setting "- - -".
"0" setting generally does not pose a problem but
you can adjust the time (0 to 5s, - - -) according
to the magnitude of the load.
When the restart coasting time (Pr. 57) has
elapsed, the output voltage is risen gradually.
Set this cushion time (0 to 60s).
Operation may be performed generally at the
factory setting, but you can adjust the time
according to the magnitude of the load.
