sage will ash on the keypad. Press RESET button on the keypad or activate the reset function through the
multi-function inputs to reset the OL1 fault.
08-06=1: When the inverter detects a motor overload the inverter will continue running and the OL1 alarm mes-
sage will ash on the keypad until the motor current falls within the normal operating range.
Code Parameter Name / Range
08-08 Automatic voltage regulation (AVR)
0: AVR is enabled
1: AVR is disabled
Automatic voltage regulation stabilizes the motor voltage independent of uctuation to the input voltage.
08-08=0: Automatic voltage regulation is active. It will limit the maximum output voltage. When input three-
phase voltage uctuates and the voltage is smaller than the value of 01-14, the output voltage will uctuate with
the uctuation of input voltage.
08-08=1: Automatic voltage regulation is not active, motor voltage follows the input voltage uctuation. When
input three-phase voltage uctuates, the output voltage won’t uctuate with the uctuation of input voltage.
Code Parameter Name / Range
08-09 Selection of input phase loss protection
0: Disable
1: Enable
08-09=0: Input phase loss detection is disabled.
08-09=1: Input phase loss detection is enabled. Keypad shows “IPL input Phase Loss” (IPL), when an input
phase loss is detected the inverter output is turned off and the fault contact is activated.
Note: The input phase loss detection is disabled when the output current is less than 30% of the inverter rated current.
Code Parameter Name / Range
08-10 Selection of output phase loss protection
0: Disable
1: Enable
08-10=0: Output phase loss detection is disabled.
08-10=1: Output phase loss detection is enabled. Keypad shows “OPL Output Phase Loss” (OPL), when an
output phase loss is detected and the inverter output is turned off and the fault contact is activated.
Note: The output phase loss detection is disabled when the output current is less than 10% of the inverter rated current.
Code Parameter Name / Range
08-13 Selection of over-torque detection
0: Over-torque detection is disabled
1: Start to detect when reaching the set frequency
2: Start to detect when the operation is begun
08-14 Selection of over-torque action
0: Deceleration to stop when over-torque is detected.
1: Displays warning when over-torque is detected. Continue operation.
2: Coast to stop when over-torque is detected
08-15 Level of over-torque detection
0~300 %
08-16 Time of over-torque detection
0.0~10.0 s
08-17 Selection of low-torque detection
0: Low-torque detection is disabled
1: Start to detect when reaching the set frequency
