Configuration

Configuration of the control source

The Altivar 212 can receive commands and setpoint from the Modbus network or from the terminals (F, R, RES, VIA, VIB). In the default configuration, both commands and setpoint come from the terminals.

The LOC/REM key of the operation panel is available to switch the control to the operation panel. The inputs F, R or RES can be configured to switch the control from the Modbus network to the terminals.

Different usual possibilities are described in the chapters below:

•Control from the Modbus network,

•Control from the terminals, monitoring from the Modbus network,

•Control from the Modbus network or the terminals, switched via Modbus,

•Command from the Modbus network, setpoint from the Modbus network or the terminals switched to by a

logic input.

Refer to these examples.

Control by the Modbus network

The commands and the setpoint come from the Modbus network. The signals wired on the terminals are ignored. The LOC/REM key is valid.

Below is the list of parameters that must be configured.
