Front module with integrated local control

The following figure shows the front module with integrated local control:

The front module is used for local mode at one speed. Local mode is implemented via the firmware function "Prioritized terminal control".

Optionally, you can switch between 2 setpoint speeds by using an additional digital input.

In local mode, the digital inputs DI05 – DI07 control the drive in manual mode. Therefore, in manual mode, no sensors can be evaluated via the digital inputs DI05 – DI07. The feedback contact of the key switch (DI08) indicates whether the decentralized inverter is in automatic or manual mode.

The following table shows the function of the digital inputs depending on the position of S2 key switch:
