the temperature is over 45 degree Celsius and fan stops when the temperature
is lower than 40 degree Celsius. Fan runnes immediately when the frequency
inverter running.
2. When frequency inverter close down, fan stops. And fan running relates to
the temperature
fan run or no relates to the module temperature. Fan operates when the
temperature is over 45 degree Celsius and stops when the temperature is lower
than 40 degree Celsius. Fan stops running immediately when the frequency
inverter is close down.
Tips: the proper use of this function can effectively prolong the life of
cooling fans.

LED 0 digit: over voltage stall protection selection

When the frequency inverter decelerates, as a result of the load inertial
influence, voltage generated by the motor will be feedbacked to frequency
inverter interior, which will lead the DC bus voltage of the frequency inverter
rise and over the maximum permission values. If no measures are taken to solve
the problem, voltage protection will works. If user start the over voltage stall
protection function, when the inverter finds DC bus voltage is too high,
frequency inverter deceleration will be ceased (to halt the decline in output
frequency). The frequency inverter will not implement the deceleration again
until the DC bus voltage is below the protection value.
While the frequency inverter is in operation, whether
