4-61
06.05
Over-Torque Detection Time (OL2) Unit: 0.1
Settings 0.1 to 60.0 sec Factory Setting: 0.1
 This parameter sets the time for how long over-torque must be detected before “OL2” is displayed.
06.06
Electronic Thermal Overload Relay Selection (OL1)
Factory Setting: 2
Settings 0 Operate with a Standard Motor (self-cooled by fan)
1 Operate with a Special Motor (forced external cooling)
2 Operation disabled
 This function is used to protect the motor from overloading or overheating.
