Commissioning (software)
7.1 Overview of commissioning
● Axis and drive configuration can initially be performed independently of one another.
● Communication connections are established automatically during the configuration of I/O
variables on SINAMICS I/Os (telegrams are set up automatically, the I/Os interconnected
to the telegram and the addresses set up).
Apart from the symbolic assignment, no further configuration is required for the communication.
As addresses no longer have to be configured, the connection is retained even with address
offsets.
Note
During the configuration of drive objects (DO drive, DO encoder, ...) as well as in the Telegram
Configuration dialog box (see Section Telegram configuration (Page 271)), you can deactivate
the automatic telegram configuration and the automatic telegram adaptation.
As many of the previously described advantages are lost through a deactivation, we
recommend that a deactivation only be performed in exceptional circumstances.
The symbolic assignment enables an independent configuration of the axes on the SIMOTION
side and the drives on the SINAMICS side.
This enables, for example:
● The PLC and motion control functions to be completely configured by a programmer even
without drive know-how using technology objects (e.g. TO axis) and loaded to the device.
● The drives to be separately configured and optimized by a drive expert.
● The technology objects to be symbolically assigned later to the drive objects via an
interconnection dialog box.
Note
The previous methods of drive, axis and I/O configuration are still available.
Symbolic assignment must be deactivated for these methods.
For newly created projects, the symbolic assignment is used by default.
If projects < V4.2 are upgraded, the symbolic assignment is deactivated by default and
must be activated when required.
Symbolic assignment can be activated/deactivated in SIMOTION SCOUT via the
"Project" > "Use symbolic assignment" menu.
Activating symbolic assignment later
Symbolic assignment simplifies the configuration of the technological relationships including
the communication between controller and drive significantly. The names of the symbolic
assignments in plain text is also advantageous for project maintenance.
Symbolic assignment is therefore recommended for new projects as of V4.2 and is
automatically active.
If symbolic assignment is used in a project, telegrams, interconnections and addresses are
automatically created by the engineering system by default.
The engineering system sets the "optimal" PROFIdrive telegrams and telegram extensions for
the system, makes the required BICO interconnections and determines the addresses.
