Automatic voltage regulation stabilizes the motor voltage independent of fluctuation to the input voltage.
08-08=0
: Automatic voltage regulation is active. It will limit the maximum output voltage. When three-phase input
voltage fluctuates and the voltage is smaller than the value of 01-14, the output voltage will fluctuate in sync with the
input voltage.
08-08=1
: Automatic voltage regulation is not active, motor voltage follows the input voltage fluctuation. When three-
phase input voltage fluctuates, the output voltage will not fluctuate in sync with the input voltage.

: 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 AC Drive 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 AC Drive rated current.

: Output phase loss detection is enabled. When an output phase loss is detected the AC Drive output is
turned off , AC Drive fault contact is activated and the keypad shows "OPL Output Phase Loss" (OPL),
Note:
The output phase loss detection is disabled when the output current is less than 10% of the AC Drive rated current.
Over-torque Detection
The over torque detection function monitors the AC Drive output current or motor torque and can be used to detect
an increase in AC Drive current or motor torque (e.g. heavy load).
The torque detection level (08-15) is based on the AC Drive rated output current (100% = AC Drive rated output
current) when operating the AC Drive in V/F control and motor output torque (100% = motor rated torque) when
operating the AC Drive in SLV control.
