bControl in Drivecom profile via Modbus and reference switching at the terminals

The command comes from Modbus.

The command comes either from Modbus or from the terminals. Input LI5 at the terminals is used to switch the reference between Modbus and the terminals.

The command is in Drivecom profile.

Configure the following parameters:

Parameter	Value	Comment
Profile	Separate Drivecom profile	The run commands follow the Drivecom profile, and the command and
		reference can come from different channels.

Reference 1 configuration	Network card	Reference 1 comes from Modbus.

Reference 1B configuration	Analog input 1 on the terminals	Reference 1B comes from input AI1 on the terminals.

Reference switching	Input LI5	Input LI5 switches the reference (1 ↔1B).

Command 1 configuration	Network card	Command 1 comes from Modbus.

Command switching	Channel 1	Channel 1 is the command channel.

Note: Reference 1B is directly connected to the drive reference limit. If switching is performed, the functions that affect the reference (summing, PID, etc) are inhibited.

Configuration via the graphic display terminal or the integrated display terminal:

	Menu		Parameter	Value
