06.03 Over-Torque Detection Mode (OL2)
Factory Setting: 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 or OL occurs.
4 Over-Torque detection enabled during acceleration. After over-
torque is detected, stop running.
 This parameter determines the operation mode of the drive after the over-torque (OL2)
 This parameter determines the operation mode of the drive after the over-torque (OL2) is
detected via the following method:
1. if the output current exceeds the over-torque detection level (Pr.06.04) and the detection
time is longer than the setting of Pr.06.05 Over-Torque Detection Time, the warning message
“OL2” is displayed on digital keypad (optional). It needs to press “RESET” to clear the warning
message.
2. If a Multi-function Output Terminal is set to over-torque detection (Pr.03.00~03.01=04), the
output is on. Please refer to Pr.03.00~03.01 for details.
 Setting 1 or 2: it is used to detect with constant speed. For setting 2, it will free run to stop after
over-torque is detected.
 Setting 3 or 4: it is used to detect during acceleration. For setting 4, it will free run to stop after
over-torque is detected.
