Travel To Fixed Stop - Siemens SINAMICS S120 Function Manual

Function modules
9.8 Basic positioner
The following parameters are relevant:
● p2616[x] Block number
● p2622[x] Task parameter = bit-coded output:
0x1: Output 1
0x2: Output 2
0x3: Output 1 + 2
Possible continuation conditions are END, CONTINUE_ON-THE-FLY and
CONTINUE_WITH_STOP, and CONTINUE_EXTERNAL_WAIT.
You can assign the binary signals to digital outputs:
● r2683.10 ≙ Output 1
● r2683.11 ≙ Output 2
Any two of the SET_O, RESET_O and GOTO tasks can be processed in an interpolation cycle
and a subsequent POSITION and WAIT task can be started.

Travel to fixed stop

Function description
The "Travel to fixed stop" function can be used, for example, to traverse sleeves to a fixed stop
against the workpiece with a predefined torque. In this way, the workpiece can be securely
clamped. The clamping torque can be parameterized in the traversing task (p2622). An
adjustable monitoring window for travel to fixed stop prevents the drive from traveling beyond
the window if the fixed stop should break away.
In positioning mode, travel to fixed stop is started when a traversing block is processed with the
FIXED STOP command. In this traversing block, in addition to the specification of the dynamic
