Chapter 12 Description of Parameter SettingsME300
Restart after Fault Action
Default: 0
Settings 0: Stop operation
1: Speed tracking by current speed
2: Speed tracking by minimum output frequency
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 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.
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 (230V models)
Frame E and above = Pr.06-00 + 80 V / 40 V (230V models)
Lv level: Default is Pr.06-00.
During dEb operation, other protection, such as ryF, ov, oc, occ, and EF may interrupt it, and these
error codes are recorded.
