Activating

Option
The function "Extended stop and retract" is an option.
Axis-specific function enable ($AA_ESR_ENABLE)
The axis-specific function enable is realized using the system variable:
$AA_ESR_ENABLE[<axis>] = 1
Axis-specific enable for extended stopping
An axis is enabled for extended stopping with:
MD37500 $MA_ESR_REACTION[axis] = 22
Axis-specific enable for retraction
An axis is enabled for retraction using:
MD37500 $MA_ESR_REACTION[axis] = 21
Channel-specific trigger ($AC_ESR_TRIGGER)
ESR is triggered on a channel-for-channel basis by setting the following system variable:
$AC_ESR_TRIGGER = 1
ESR is then realized in all channel axes for which the following applies:
$AA_ESR_ENABLE[<axis>] == 1 AND MD37500 $MA_ESR_REACTION[axis] == 21 OR 22

Configuring aids for ESR

Voltage failure
For the following modules, when the line voltage fails, the power supply must be maintained
using suitable measures at least until it is ensured that the axes have come to a stop..
