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.
