Chapter 12 Description of Parameter Settings
Treatment after Fault
Settings
In PG control mode, the AC motor drive will execute the speed search function automatically by
the PG speed when this setting isn't set to 0.
Fault includes: bb,oc,ov,occ. To restart after oc, ov, occ, Pr.07-11 can not be set to 0.
Auto Restart Time after Fault
Settings 0~10
After fault (oc, ov, occ) occurs, the AC motor 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 motor drive will restart with Pr07-10 setting after fault auto reset.
If the time of reset/restart exceeds Pr.07-11 setting, the fault will not be restart /reset until user
reset manually and run the motor drive again.
Speed Search during Start-up
Settings
This parameter is used for starting and stopping a motor with a high inertia. A motor with high
inertia will take 2-5 minutes or longer to stop completely. By setting this parameter, the user
does not need to wait for the motor to come to a complete stop before restarting the AC motor
drive. If a PG card and encoder is used on the drive and motor, then the speed search will start
from the speed that is detected by the encoder and accelerate quickly to the commanded
frequency. The output current is set by the Pr.07-09.
In PG control mode, the AC motor drive will execute the speed search function automatically by
the PG speed when this setting isn't set to 0.
