bControl via Modbus in Drivecom profile

The command and reference come from Modbus.

The command is in Drivecom profile.

Configure the following parameters:

Parameter	Value	Comment
Profile	Drivecom profile not	The run commands are in Drivecom profile, the command and the reference
	separate	come from the same channel.
Reference 1 configuration	Network card	The command comes from Modbus.

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

Menu	Parameter	Value
[1.6 - COMMAND] (CtL-)	[Profile] (CHCF)	[Not separ.] (SIM) (factory setting)

	[Ref. 1] (Fr1)	[Com. card] (nEt)

bControl via Modbus or the terminals in Drivecom profile

Both the command and reference come from Modbus or the terminals. Input LI5 at the terminals is used to switch between Modbus and the terminals.

The command is in Drivecom profile.

Configure the following parameters:

Parameter	Value	Comment
Profile	Drivecom profile not separate	The run commands follow the Drivecom profile, and the command and
		reference come from the same channel.
Reference 1 configuration	Network card	Reference 1 comes from Modbus.

Reference 2 configuration	Analog input 1 on the terminals	Reference 2 comes from input AI1 on the terminals.

Reference switching	Input LI5	Input LI5 switches the reference (1 ↔ 2) and the command.

Caution: Reference 2 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
[1.6 - COMMAND] (CtL-)	[Profile] (CHCF)	[Not separ.] (SIM)

	[Ref.1 channel] (Fr1)	[Com. card] (nEt)

	[Ref.2 channel] (Fr2)	[Ref. AI1] (AI1)

	[Ref. 2 switching] (rFC)	[LI5] (LI5)
