(2) When 08-07=1, The inverter is supplied by power, the fan start to run. If inverter stop to run
longer than 08-30, the fan start to stop.
(3) When 08-07=2, The inverter is supplied by power, the fan start to run.
(4) When 08-08=3, The fan will not run.
Note：
When 08-07=0, if inverter sto, but the heatsink terperature is still too high, the cooling fan will start
to run.
08- 08 Automatic voltage regulation (AVR)
Range
【0】：AVR is enabled
【1】：AVR is disabled
Automatic voltage regulation stabilizes the motor voltage independent of fluctuation to the
input voltage.
(1) When 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.
(2) When 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 Selection of input phase loss protection
Range
【0】：Disable
【1】：Enable
(1) When 08-09=0：Input phase loss detection is disabled.
When 08-09=1：Input phase loss detection is enabled.
(2) 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.
(3) The input phase loss detection is disabled when the output current is less than 30% of the
inverter rated current.
08- 10 Selection of output phase loss protection
Range
【0】：Disable
【1】：Enable
When 08-10=0：Output phase loss detection is disabled.
When 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.
The output phase loss detection is disabled when the output current is less than 10% of the
inverter rated current.
08- 13 Selection of over-torque detection
Range
【0】：Over-torque detection is disabled
【1】：Start to detect when reaching the set frequency
【2】：Start to detect when the operation is begun
