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 right arrow menu button. The present mode shown starts to blink. Use the Browser buttons to change the fan mode. Accept the change with the Enter button or return to the previous level with the left arrow menu button.

Note! If the frequency converter has been connected to the PC with a normal cable, the default values of parametres 6.3.6 and 6.3.7 (200 and 5) must not be changed.
If the frequency converter has been connected to the PC via a modem and there is a delay in transferring messages, the value of par. 6.3.6 must be set according to the delay as follows:
