
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.

Speed Tracking during Start-up
Default: 0
Settings 0: Disable
1: Speed tracking by maximum output frequency
2: Speed tracking by motor frequency at start
3: Speed tracking by minimum output frequency
 Speed tracking is suitable for punch, fans and other large inertia loads. For example, a
mechanical punch usually has a large inertia flywheel, and the general stop method is coast to
stop. If it needs to be restarted again, the flywheel may take 2–5 minutes or longer to stop. This
parameter setting allows you to start the flywheel operating again without waiting until the
flywheel stops completely.

dEb Function Selection
Default: 0
Settings 0: Disable
1: dEb with auto-acceleration/auto-deceleration, the drive does not output the
frequency after the power is restored.
2: dEb with auto-acceleration/ auto-deceleration, the drive outputs the
frequency after the power is restored.
 dEb (Deceleration Energy Backup) lets the motor decelerate to stop when momentary power loss
occurs. When the power loss is instantaneous, use this function to let the motor decelerate to
zero speed. If the power recovers at this time, the drive restarts the motor after the dEb return
time.
 Lv return level: Default value depends on the drive power model.
Frame A, B, C, D = Pr.06-00 + 60 V / 30 V (220V series)
Frame E and above = Pr.06-00 + 80 V / 40 V (220V series)
