Comment
What is shown in parameter r9713 is identical to the values of r9708; however, in
SINAMICS-internal calculation units.
Speed c alculation
The control must calculate the speed from the position change:
●
Pos diff = Pos new - Pos old
●
Cycle diff = cycle counter new - cycle counter old
●
Timediff = Cyclediff × Safetycycle
(If
●
v = Pos diff/time diff
●

Acceptance test
An acceptance test is not required for the "Transfer safe position values" function, but the
function that was implemented with the aid of SP must be accepted in the higher-level
controller.
