Current Limit for Speed Search

Settings 20~200%
Following a momentary power loss, the AC motor drive will start its speed search operation only if
the output current is greater than the value set by Pr.07-09.
When executing speed search, the V/f curve is operated by group 1 setting. The maximum current
for the optimum accel./decel. and start speed search is set by Pr.07-09.
The speed search level will affect the synchronous time. It will get the synchronization faster when
this parameter is set to larger value. But too large value may active overload protection.

Treatment to Reboots After Fault

Settings 0: Stop operation
In PG control mode, the AC motor drive will execute the speed search function automatically by
the PG speed when this setting isn't set to 0.
