08-07=2:
Fan turns on when the heat-sink temperature rises above the maximum heat-sink temperature. When
the heat-sink temperature falls below the maximum heat-sink temperature for the time specified in 08-38, the fan
turns off.
Note:
The cooling fan stays running when 08-07=0 and the heatsink temperature is still above the maximum
heat-sink temperature

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 input three-phase
voltage fluctuates and the voltage is smaller than the value of 01-14, the output voltage will fluctuate with the
fluctuation of input voltage.
08-08=1:
Automatic voltage regulation is not active, motor voltage follows the input voltage fluctuation.
When
input three-phase voltage fluctuates, the output voltage won
’t fluctuate with the fluctuation of input voltage.

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.

08-10=1:
Output phase loss detection is enabled. When an output phase loss is detected the inverter output is
turned off , inverter 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 inverter rated
current.
