Over-Torque Detection Mode (OL2) Factory Setting: 00
Settings 00 Over-Torque detection disabled.
01 Over-Torque detection enabled during constant speed operation,
and keep operation after the over-torque is detected.
02 Over-Torque detection enabled during constant speed operation,
and operation halted after over-torque detection.
03 Over-Torque detection enabled during acceleration, and keep
operation after the over-torque is detected.
04 Over-Torque detection enabled during acceleration, and
operation halted after over-torque detection
This parameter determines the operation mode of the drive after the over-torque is
detected with the following method: if the output current exceeds the over-torque
detection level (Pr.06-04) and which also exceeds the setting of Pr.06-05 Over-Torque
Detection Time, with the [Multi-Functional Output Terminal] specified as an indication for
the over-torque detection, the contact will then be “closed”. Please refer to
Pr.03-00~03-03 for detail.
06 - 04
Over-Torque Detection Level Factory Setting: 150
Settings 10 to 200% Unit: 1%
This setting is proportional to the Rated Output Current of the drive.
06 - 05
Over-Torque Detection Time Factory Setting: 0.1
Settings 0.1 to 60.0Sec Unit: 0.1sec
This parameter determines the time for over-torque detection.
06 - 06
Electronic Thermal Overload Relay Selection Factory Setting: 00
Settings 00 Operate with a Standard Motor (coaxial heat dissipation)
01 Operate with a Special Motor (independent heat dissipation)
02 Operation disabled
This function is used to protect the motor from overload or overheat.
06 - 07
Electronic Thermal Characteristic
a
Factory Setting: 60
Settings 30 to d 600 Sec Unit: 1 Sec
The parameter determines the time required activating the I
2
t electronic thermal
protection function. The graph below shows I
2
t curves for 150% output power for 1
minute.
