7.1.15 Travel to fixed stop
Description
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 built up and remains
applied.
The desired torque derating is brought about by scaling the upper/motor-mode torque limit
and the lower/regenerative-mode torque limit.
Application examples
● Screwing parts together with a defined torque.
● Moving to a mechanical reference point.
Signals
When PROFIBUS telegrams 2 to 4 are used, the following are automatically interconnected:
● Control word 2, bit 8
● Status word 2, bit 8
Also with PROFIdrive telegrams 102 and 103:
● Message word, bit 1
● Process data M_red to the scaling of the torque limit
