Hi!

I am dealing with a slightly unconventional motor setup where two limit
switches are used for two motor axes in the following way:

-limit switch 1 acts as the high limit for controller 1 and low limit
for controller 2
-limit switch 2 acts as the low limit for controller 1 and high limit
for controller 2

This means the status of the limit switches of an axis can change even
if its motor is stopped. The motor record does not seem to expected a
behavior like that - at least not with the Parker PC6K device support.
The limits are only updated while the motor is moving.

I tried a caput to the STUP field but that didn't have any effect. Is
there a way to force the motor record to update the status of the
switches? This might also be helpful for simple multi-axis operation
with a single home switch.

Any help is greatly appreciated,

Martin
