8.2 Run Commands
This chapter explains the permitted modes of operation during positioning:
8.2.1 Moving to Absolute Position
Description of the function
The absolute mode is used to move the stepper motor to a defined position and thus ap-
proach a specified position.
You define the position at start. The TM StepDrive automatically determines the direction
and distance of the drive based on the starting position (actual position value).
Traversing job for absolute positioning
The traversing job contains the following information:

Control value = target position

Run command = 1

Acceleration and run frequency via DS128
i
The axis must be referenced; otherwise, the command is not accepted. Referenc-
ing can be done either by a reference point search or by setting the position.
i
If the "Travel range" parameter has a value other than zero, the TM StepDrive
checks the specified travel distance for the parameterised limit values ("Travel
range" parameter). The distance to the limit switch is not checked by the TM
StepDrive. The travel is stopped at the latest when the limit switch is reached. The
emergency stop ramp is used (10 times steepness of the set acceleration).
Feedback
At the beginning of positioning, the "READY" feedback bit is reset.
As long as the positioning is running, this is indicated by the "Motor running" feedback bit
set.
After positioning has run correctly, the position is indicated by the "READY" feedback bit
set.
If positioning is cancelled due to an error, this can be seen from the error bits (e.g. limit
switch error).
8.2.2 Moving a Relative Distance
Description of the function
With relative positioning, you can move the stepper motor a defined distance and thus
move to a specific position. You determine the direction of the trip and the route to be driv-
en at the start.
