Servo control
4.17 Travel to fixed stop
Drive functions
174 Function Manual, 11/2017, 6SL3097-4AB00-0BP5
This function can be used to move a motor to a fixed stop at a specified torque without a
fault being signaled. When the stop is reached, the specified torque is established and is
then continuously available.
The desired torque derating is brought about by scaling the upper/motor-mode torque limit
and the lower/regenerative-mode torque limit.
● Screwing parts together with a defined torque.
● Moving to a mechanical reference point.
For PROFIdrive telegrams 2 to 6, the following signals are automatically interconnected:
● Control word 2, bit 8 (STW2.8)
● Status word 2, bit 8 (ZSW2.8)
For PROFIdrive telegrams 102 to 106, the following signals are also interconnected:
● Message word, bit 1 (MELDW1)
● Process data M_red to the scaling of the torque limit
When the "basic positioner" function module is activated, the signals listed above are
automatically interconnected to the basic positioner.
