Chapter 12 Descriptions of Parameter SettingsC2000 Plus
12.1-07-5
07-09
Current Limit of Speed Tracking
Default: 100
Settings 20–200%
230V / 460V models: 100% corresponds to the heavy duty rated current of the drive, refer to Pr.00-
01 for details.
575V / 690V models: 100% corresponds to the rated current of the drive (Pr.00-01).
The AC motor drive executes speed tracking only when 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.
07-10
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 and occ. To restart after oc, ov and occ, you can NOT set Pr.07-11 to 0.
07-11
Number of Times of Restart after Fault
Default: 0
Settings 0–10
After fault (oc, ov and occ) occurs, the AC motor drive can reset and restart automatically up to 10
times. If Pr.07-11 is set to 0, the drive resets or restarts automatically after faults occur. The drive
starts according to the Pr.07-10 setting after restarting after fault.
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.
