Current Limit for Speed Search
Factory Setting: 100
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 maximum 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 activate overload
protection.

Treatment after Fault
Factory Setting: 0
Settings 0: Stop operation
1: Speed search starts with current speed
2: Speed search starts with minimum output frequency
 Fault includes: bb,oc,ov,occ. To restart after oc, ov, occ, Pr.07-11 can not be set to 0.
