Behavior For Reset And Function Abort - Siemens SINUMERIK 840D sl Function Manual

Deactivating FXS-REPOS
FXS-REPOS is deactivated by:
● An FXS synchronized action which refers to REPOSA
● $AA_FXS[X] = $VA_FXS[X] in the SERUPRO_ASUB
Note
A SERUPRO ASUB without FXS treatment or no SERUPRO ASUB results automatically
in FXS-REPOS.
FOC-REPOS
FOC-REPOS behaves in the same way as FXS-REPOS.
A changing torque characteristic during the program preprocessing cannot be implemented
with FOC-REPOS.
Example
Axis X is traversed from position 0 to 100. FOC is switched on every 20 millimeters for 10
millimeters. The resulting torque characteristic is generated with non-modal FOC and cannot
be traced by FOC-REPOS. Axis X is traversed by FOC-REPOS with or without FOC in
accordance with the last programming before the target block.
For programming examples of FXS "Travel to fixed stop", see Section "Program test
(Page 471)".

Behavior for reset and function abort

NC reset
As long as the function is still not in the "Successful travel to fixed stop" state, the travel to
fixed stop can be aborted with NC reset.
Even when the fixed stop has already has been approached, but the specified stop torque not
yet fully reached, then the function can still be aborted with NC reset. The position setpoint of
the axis is synchronized with the current actual position.
As soon as the function is in the "Successful travel to fixed stop" state, the function also remains
active after the NC reset.

CAUTION
Speed too high for FXS-REPOS
FXS-REPOS traverse all path axes together to the target position. Axes with and without
FXS treatment thus traverse together with the G code and feedrate valid in the target block.
As a result, the fixed stop may be approached in rapid traverse(G0) or higher velocity.
