08.08 Current Limit for Speed Search Unit: 1
Settings 30 to 200% Factory Setting: 150
 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.08.08. When the output current is less than the value of Pr.08.08,
the AC motor drive output frequency is at “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 loss.

 These parameters set the Skip Frequencies. It will cause the AC motor drive never to remain within these
frequency ranges with continuous frequency output.
 These six parameters should be set as follows Pr.08.09 ≥ Pr.08.10 ≥ Pr.08.11 ≥ Pr.08.12 ≥ Pr.08.13 ≥ Pr.08.14.
 The frequency ranges may be overlapping.

Auto Restart After Fault Unit: 1
Settings 0 to 10 Factory Setting: 0
0 Disable
 Only after an over-current OC or over-voltage OV fault occurs, the AC motor drive can be reset/restarted
automatically up to 10 times.
 Setting this parameter to 0 will disable automatic reset/restart operation after any fault has occurred.
When enabled, the AC motor drive will restart with speed search, which starts at the frequency before the fault.
To set the waiting time before restart after a fault, please set Pr. 08.07 Base Block Time for Speed Search.
08.16
Auto Reset Time at Restart after Fault Unit: 0.1
Settings 0.1 to 6000 sec Factory Setting: 60.0
 This parameter should be used in conjunction with Pr.08.15.
For example: If Pr.08.15 is set to 10 and Pr.08.16 is set to 600s (10 min), and if there is no fault for over 600
seconds from the restart for the previous fault, the auto reset times for restart after fault will be reset to 10.
