Travel with limited torque/force (FOC)

During repositioning (REPOS), the "Travel with limited torque/force" function (FOC) is repeated
automatically. Every axis is taken into account. The torque programmed last before the search
target is used as torque.
System variable
The system variables for "Travel with limited torque/force" have the following meaning with
SERUPRO:
● $AA_FOC: Progress of the program simulation
● $VA_FOC: Real machine state
Supplementary condition
A changing torque characteristic cannot be implemented during repositioning.
Example
A program traverses axis X from 0 to 100 and switches "Travel with limited torque/force"
(FOC) on every 20 increments for 10 increments. This torque characteristic is usually generated
with non-modal FOC and cannot be performed during repositioning (REPOS). Instead, axis X
is traversed from 0 to 100 with or without limited torque/force in accordance with the last
programming.
