Commissioning - Siemens Sinamics S120 Function Manual

If the "position control" function module is selected, these parameters (p2508 to p2511) are
preassigned with "0". If the "basic positioner" function module is selected, the functions
"reference mark search" (for the function reference point search) and "measuring probe
evaluation" (for the function flying referencing) are initiated by the function module basic
positioner and the feedback signal (r2526, r2523) is fed back to this (also see Chapter
Control and status words for encoder (Page 553)).

Commissioning

The "positon control" function module is integrated in the system as follows:
Commissioning
The configuration screen for "Position control" in STARTER is not made accessible unless
the function module "Basic positioner" is activated (r0108.4 = 1) which means that the
function module "Position control" (r0108.3 = 1) is automatically activated as well.
The "basic positioner" function module can be activated via the commissioning wizard or the
drive configuration (configure DDS) (configuration "Closed-loop control structure" - checkbox
"Basic positioner").
To ensure correct, error-free operation of the basic positioner, it is absolutely essential that
the "Position control" function module is activated and the position control correctly
configured.
