Chapter 4 Parameters 
4-128
 These parameters are used to set the frequencies that are inhibited to operate. This function
can be used to prevent the resonance generated from the original frequency of the machines.
It keeps the drive from running at the resonance frequency of machinery or load system or
other inhibition frequency. There are three frequency areas can be set.
 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. When it is
set to 0.0, the skip frequency is invalid.
 The frequency command (F) can be set within the range of skip frequency. At this moment, the
output frequency (H) will be less than the lower limit of skip frequency.
 When the drive accelerates/decelerates, the output frequency will pass the range of skip
frequency.

Auto Restart After Fault
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.

When the fault times exceeds Pr.08.15 setting, the drive will refuse to restart and the user
needs to press “RESET” for continuous operation.
 Related parameter: Pr.08.16 (Auto Reset Time at Restart after Fault)
08.16
Auto Reset Time at Restart after Fault Unit: second
Settings 0.1 to 6000 sec Factory Setting: 60.0
 This parameter is used to set the auto reset time at restart after fault. After restarting for fault, if
there is no fault for over Pr.08.16 setting from the restart for the previous fault, the auto reset
times for restart after fault will be reset to Pr.08.15 setting..
 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
