Fan control (P6.7.2)
This function allows you to control the AC drive’s cooling fan. You can set the fan to run continuously 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 140 F (60 C) or the
converter is in RUN state. The fan receives a stop command when the heat sink temperature falls to 131 F
(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 AC drive 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 AC drive 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:
