17.2 Fan
The switch-on temperature of the heat sink fan can be set with the parameter
Switch-
on temperature
39.
If mains voltage is applied to the frequency inverter, and the heat sink temperature
exceeds the set temperature, the heat sink fan is switched on. Independent from pa-
rameter
Switch-on temperature 39, the heat sink fan will be switched on, as soon as
the frequency inverter is switched on and enabled and the start signal is received.
If the heat sink temperature drops below the set temperature by 5 °C, or if the con-
troller enable signal is inhibited, the heat sink fan is switched off when the minimum
ON-time has elapsed.
The minimum ON-time of the heat sink fan is set internally to 1 minute. When the
temperature drops below the
Switch-on temperature 39 during this time since start-
ing, the fan will continue to operate until the running ON-time is reached.
Operation mode 43 for digital outputs additionally enables the control of an exter-
nal fan. Via the digital output, the fan is switched on if the controller is released and
Start clockwise or Start anticlockwise are switched on, or if the Switch-on temperature
39 for
the internal fan was reached.
Like in the case of the internal heat sink fan, the minimum ON-time of the external fan
is 1 minute.

17.3 Bus controller
Note: In order to be able to control the drive, the digital controller input S1IND
must be connected and set to "High-Signal" in order to enable the out-
put stage.
Warning!
• Switch off power supply before connecting and disconnecting control
terminal S1IND.
• The unit may only be connected with the power supply switched off.
• Make sure that the frequency inverter is discharged.
• When the frequency inverter is disconnected from power supply, the
mains, DC-link voltage and motor terminals may still be live for some
time. Wait for some minutes until the DC link capacitors have dis-
charged before starting to work at the unit.
The frequency inverters can be extended by different options for data communication
and can be integrate in an automation and control system in this way. Parameteriza-
tion and commissioning can be done via the optional communication card, the operat-
ing unit or the interface adapter. The parameter
Local/Remote 412 defines the oper-
ating behavior and enables a change between the control via contacts or the control
unit and/or the interface.
