Fan control (P6.3.4)

This function allows the control of the frequency converter’s cooling fan. When the power is
switched on the fan can be set to run continuously or dependant on the temperature of the unit. If
the latter function has been selected the fan is switched on automatically when the heat sink
temperature reaches 60

C. The fan receives a stop command when the heat sink temperature

falls to 55

C. However the fan runs for about a minute after receiving the stop command, as well

as after changing the value from Continuous to Temperature.

Enter the edit mode by pushing the

Enter button

or return to the previous level with the
