ć A force task can always be started from a position−conĆ
trolled or force−controlled status. Depending on the initial
status, different types of behaviour are possible:
ć The axis is positioned force−controlled or position−conĆ
trolled (MC=1): A new force task is started immediĆ
ately.
ć The axis is carrying out a positioning task (MC=0):
On−the−fly change of controller": the current positionĆ
ing task is ended with the set stop ramp. As soon as
the speed = 0, the force task is started. MC always
remains = 0.
ć The axis is carrying out a force task (MC=0), the new
force task has the same direction of force:
On−the−fly sequencing": The new force task is started
immediately. MC always remains = 0.
ć The axis is carrying out a force task (MC=0), the new
force task has the opposite direction of force:
On−the−fly reversing": The current force task is ended
with a configured ramp, as soon as the force value
reaches 0" the new force task is started. MC always
remains = 0.
