Control of an ATV 312 from a PROFIBUS DP option card

There are several ways to control an ATV 312 from a communication card:

•The control word and the speed reference are controlled from the network in the same time.

•The control word and the speed reference come from separate sources.

However, separate mode is only allowed when the [ACCESS LEVEL] (LAC) parameter in the [COMMAND] (CtL-)menu is set to L3. The control of the drive is also detailed in the programming manual of the ATV312 in the chapter "Control Menu".

Control of the drive when LAC = L1 or L2

There is no particular settings, the channels are managed in order of priority.

Terminals/Keypad

Remote display terminal

or any communication option

Control of the drive when LAC = L3

When configured with LAC = L3, several configurations are possible:

•Control and reference come from the communication card,

•Control via PROFIBUS DP or the terminals in native profile (CiA402),

•Control is separated from reference channel.

Configure the following parameters:

Parameter	Value	Comment
Profile	Combined native profile	The run commands are in native profile (CiA402), the command and the target
	(CiA402)	come from the same channel.
Target 1 configuration	Network card	The command comes from PROFIBUS DP.

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

Menu	Parameter	Value
[COMMAND] (CtL-)	[Profile] (CHCF)	[Not separ.] (SIM) (factory setting)
	[Ref.1 channel] (Fr1)	[Network] (nEt)
