06/07 Operating Instructions ACTIVE 67
The frequency inverters can be controlled by means of the control unit and/or a com-
munication module. In the CTRL menu branch, various functions are available which
make commissioning easier and enable the control of the inverter via the control unit.
If you want to control the frequency inverter via an optional communication module,
the necessary adjustments can be made via parameter
Local/Remote 412. Via this
parameter, you can specify which functions will be available to the controller. Depend-
ing on the operation mode selected, only some of the control menu functions are
available. Refer to Chapter “Bus controller” for a detailed description of the parameter
Local/Remote 412.
6.8 Controlling the Motor via the Control Unit
The control unit enables controlling the connected motor in accordance with the se-
lected operation mode of parameter
Local/Remote 412.
Note: In order to be able to control the drive via the control unit, the digital
controller input S1IND (controller release) must be connected and set to
"High-Signal" in order to enable the output 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
discharged before starting to work at the unit.
: When the RUN key was pressed, the drive was in operation already.
