Autonomous single-axis functions with NC-controlled ESR

Extended stop numerically controlled
The numerically controlled extended stop and retract function is also available for single
axes and is configurable with axial machine data:
Delay time for ESR single axis with
MD37510 $MA_AX_ESR_DELAY_TIME1
ESR time for interpolatory braking of the single axis with
MD37511 $MA_AX_ESR_DELAY_TIME2
The values of these axial machine data are however effective only if the axis/spindle is a
single axis.
The NC-controlled extended stop and retract is activated by the axial trigger
$AA_ESR_TRIGGER[axis]. It works analogously to $AC_ESR_TRIGGER and applies
exclusively to single axes.

Extended retract numerically controlled
For retracting single axes, the value must have been programmed via POLFA(axis, type,
value) and the following conditions must be met:
● The axis must be a single axis at the time of triggering
● $AA_ESR_ENABLE[axis]=1
● POLFA(axis, type, value) with type=1 or type=2 only

Note
NC-controlled extended stop for single axes:
The trigger is only effective if the axis is a single axis at the time of triggering, otherwise
the trigger is ignored and the axial stop for this axis is not executed.
NC-controlled extended retract for single axes:
The channel-specific NC-controlled extended retract function is not effective for single
axes. All axes that are single axes at the time of triggering $AC_ESR_TRIGGER will be
ignored for channel-specific retraction.
This also applies when all the parameters for retraction are set, such as:
MD37500 $MA_ESR_REACTION
$AA_ESR_ENABLE for the axis, etc.
