– Separate window in STARTER
– Separate fault/alarm system (for VECTOR, SERVO, A_INF, B_INF)
– Separate PROFIBUS telegram for process data (for VECTOR, SERVO,
A_INF, B_INF)
Optionally installed drive objects
S Infeed: Basic / Active Line Module infeed control
If a Basic or Active Line Module is used for the infeed in a drive system, the
open-loop/closed-loop infeed control is implemented on the Control Unit within a
corresponding drive object.
S Infeed: Smart Line Module infeed control
If a Smart Line Module is used for the infeed in a drive system, the Control Unit
must handle activation and evaluation of the corresponding signals (RESET,
READY).
S Option board evaluation
A further drive object handles evaluation of an installed option board. The
specific method of operation depends on the type of option board installed.
S Terminal Module evaluation
A separate drive object handles evaluation of the respective optional Terminal
Modules.
Configuring drive objects
When you commission the system for the first time using the STARTER tool, you
will use configuration parameters to set up the software-based "drive objects"
which are processed on the Control Unit. Various drive objects can be created
within a Control Unit.
The drive objects are configurable function blocks and are used to execute specific
drive functions.
If you need to configure additional drive objects or delete existing ones after initial
commissioning, the drive system must be switched to configuration mode.
The parameters of a drive object cannot be accessed until the drive object has
been configured and you have switched from configuration mode to parameteriza-
tion mode.
