E. Cn-41: V/f During Speed Search Factory setting: 100 %
Range: 0 to 100 %
To prevent a fault such as OC from occurring during the speed search operation, V/f must
be set to a value lower than that required during normal operation.
V/f during speed search = V/f at normal operation x Cn-41
F. Cn-42: Voltage Recovery Time Factory setting: 0.3 sec.
Range: 0.1 to 2.0 sec.
Sets the amount of time the drive needs to recover from zero to rated output voltage after
speed search.
