the setting for Pr.06.05, the warning message “OL2” displays. If a multi-functional output terminal
is set to over-torque (OL2) detection (Pr.03.00), the output is ON. (Refer to Pr.03.00)
Over-Torque Detection Level
Refer to Pr.06.51 to select whether the over torque level is based on the motor rated current or
the drive rated current.
When Pr.06.51 is set to 0: The over-torque level is based on the motor rated current (Pr.07.00),
set Pr.06.04 as the motor allowable overload coefficient.
When Pr.06.51 is set to 1: The over-torque level is based on the drive rated current (Pr.00.01), it
needs to be converted and calculated according to the motor rated current and overload
capacity. The calculation is as the following:
Motor rated current × Motor allowable overload factor ÷ Inverter rated current × 100%
OL2 Over-Torque Detection Level Selection
1: Based on motor's rated current (Pr.07.00)
2: Based on driver's rated current (Pr.00.01)
Over-torque Detection Time
Sets the drive action modes after over-torque detection.
Over-torque detection method: when output current exceeds the over-torque detection level
(Pr.06.04) and the detection time is longer than the setting for Pr.06.05, if the MO terminal is set
to over-torque detection, the contact is “closed”. Refer to Pr.03.00 for details.
Set the overload time corresponding to the allowable overload coefficient of the motor, which
cannot exceed the allowable overload time of the motor.
Electronic Thermal Relay Selection (oL1)
0: Standard motor (fan cooling)
1: Special motor (forced external cooling)
Sets the operation of the electronic thermal overload relay that protects the motor from
overloading or overheating.
