Examples for axes without path relationship
For the subsequent examples, path axes X and a command axis B are assumed, which are
configured as NC-controlled retraction axis:
● MD37500, $MA_ESR_REACTION[X] = 21
● MD37500, $MA_ESR_REACTION[B] = 21

Response in the case of ESR
Retraction motion in X and Y.
X does not have ESR enable. As X is a path axis, for X, the ESR response
is implicitly changed to 22 (stopping). This is the reason that X continues to
traverse corresponding to the programmed traversing motion.
Y executes retraction motion.
After the delay time for ESR axes expires, MD21380, $MC_ESR_DE‐
LAY_TIME1, X is stopped with the path acceleration.
X has no retraction enable (POLFMASK). X does not execute any retraction
motion. As X is a path axis, for X, the ESR response is implicitly changed to
22 (stopping). This is the reason that X continues to traverse corresponding
to the programmed traversing motion.
Y executes retraction motion.
After the delay time for ESR axes expires, MD21380, $MC_ESR_DE‐
LAY_TIME1, X is stopped with the path acceleration.
Y has not been enabled for retraction (POLFMASK). see lines above, syntax
Y does not execute retraction motion. As Y is a path axis, for Y, the ESR
response is implicitly changed to 22 (stopping). This is the reason that Y
continues to traverse corresponding to the programmed traversing motion.
X executes retraction motion.
After the delay time for ESR axes expires, MD21380, $MC_ESR_DE‐
LAY_TIME1, Y is stopped with the path acceleration.
