Commissioning the function

The "position control" function module is integrated in the system as follows:
Procedure
The configuration screen for "Position control" in Startdrive 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 over "Basic parameter assignment >
Function modules."
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.
If the "position control" function module is active, and to optimize the speed controller, a
function generator signal is interconnected to the speed controller input p1160, then the
position controller monitoring functions respond. To prevent this from happening, you must
disable the position controller (p2550 = 0) and switch it to the tracking mode (p2655 = 1, for
control using PROFIdrive telegram 110 PosSTW.0 = 1). In this way, the monitoring functions
are switched off and the position setpoint is tracked.
