Over-current Stall Prevention during Operation
Unit: 1
Settings 20–250% Default: 170
0: Disable
If the output current exceeds the setting for Pr.06.02 when the drive is operating, the drive decreases its output
frequency to prevent motor stall. If the output current is lower than the setting for Pr.06.02, the drive
accelerates again to catch up with the set frequency command value.

Over-torque Detection Mode (OL2)
Default: 0
Settings 0 Over-torque detection disabled.
1 Over-torque detection enabled during constant speed operation. After over-
torque is detected, keep running until OL1 or OL occurs.
2 Over-torque detection enabled during constant speed operation. After over-
torque is detected, stop running.
3 Over-torque detection enabled during acceleration. After over-torque is
detected, keep running until OL1 occurs.
4 Over-torque detection enabled during acceleration. After over-torque is
detected, stop running.
Determines the operation mode of the drive after detecting over-torque (OL2). It uses the following methods:
1. If the output current exceeds the Over-torque Detection Level (Pr.06.04) and the detection time is
longer than the setting for Pr.06.05 (Over-torque Detection Time), the warning message “OL2”
displays.
2. If a multi-functional output terminal is set to over-torque detection (Pr.03.00=4), the output is ON. Refer
to Pr.03.00 for details.
