Chapter 12 Description of Parameter Settings
MH300
Current Limit of Speed Tracking
Default: 100
Settings 20–200%
The AC motor drive executes speed tracking only if the output current is greater than the value
set in Pr.07-09.
The maximum current for speed tracking affects the synchronous time. The larger the parameter
setting is, the faster the synchronization occurs. However, if the parameter setting is too large, the
overload protection function may be activated.
Restart after Fault Action
Default: 0
Settings
0: Stop operation
1: Speed tracking by current speed
2: Speed tracking by minimum output frequency
In PG control mode, the AC motor drive executes the speed tracking function automatically
according to the PG speed when this setting is NOT set to 0.
Faults include: bb, oc, ov, occ. To restart after oc, ov, occ, you can NOT set Pr.07-11 to 0.
Number of Times of Auto-restart after Fault
Default: 0
Settings 0–10
After fault (allowed fault: oc, ov, occ) occurs, the AC motor drive can reset and restart
automatically up to 10 times.
If the number of faults exceeds the Pr.07-11 setting, the drive does not reset and restart until you
press “RESET” manually and execute the operation command again.
