5-44

! Following a power failure, the AC drive will start its speed search operation, only if the

output current is greater than the value determined by Pr.8-07. When the output current

is less than that of Pr.8-07, the AC drive output frequency is at a “speed synchronization

point”. The drive will start to accelerate or decelerate back to the operating frequency at

which it was running prior to the power failure.

! These parameters determine Skip frequency. It will cause the AC drive to skip operation

at these frequency ranges with continuous frequency output.

! Pr.8-9, Pr.8-11,Pr.8-13 are for Lower Bound setting, and the settings should follow as

Pr.8-9Pr.8-11Pr.8-13.

8 - 14 Hiba utáni autómatikus újraindítás Factory Setting: d 0

Settings d 0 to d 10

! After fault occurs (allowable faults: over-current OC, over-voltage OV), the AC drive can

be reset/restarted automatically up to 10 times. Setting this parameter to 0 will disable the

reset/restart operation after any fault has occurred. When enabled, the AC drive will

restart with speed search, which starts at the Master Frequency.
