Fan control (P6.7.2)
This function allows you to control the frequency converter’s cooling fan. You can set the fan to run con-
tinuously when the power is switched on or depending 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 or
the converter is in RUN state. The fan receives a stop command when the heat sink temperature falls to
55°C and the converter is in STOP state. However, the fan runs for about a minute after receiving the stop
command or switching on the power, as well as after changing the value from
Continuous
to
Temperature.
Note! The fan runs always when the drive is in RUN state.
Enter the edit mode by pushing the
Menu button right
. 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
Menu button left
.

HMI acknowledge timeout (P6.7.3)
This function allows the user to change the timeout of the HMI acknowledgement time in cases where
there is an additional delay in the RS-232 transmission due to use of modems for communication over
longer distances, for example.
Note! If the frequency converter has been connected to the PC with a normal cable, the default values of
parametres 6.7.3 and 6.7.4 (200 and 5) must not be changed.
If the frequency converter has been connected to the PC via a modem and there is delay in transferring
messages, the value of par. 6.7.3 must be set according to the delay as follows:
