Autonomous Single-Axis Functions With Nc-Controlled Esr - Siemens SINUMERIK 840D Function Manual

Boundary conditions
In the following cases, the request to continue is ignored:
● The axis/spindle is not controlled by the PLC.
● The axis/spindle is not in the stopped state.
● An alarm is pending for the axis/spindle.
Use case 4: Reset axis/spindle (reset)
Description of the sequence:
● PLC → NC: Reset request for this axis/spindle
DB31, ... DBX28.1 = 1 (reset)
● NC: Transitions the axis/spindle into the "stopped" state.
● NC: Interrupts the stopped sequences and signals to the PLC the interruption - essentially
the same as for "Delete distance-to-go".
● NC: The internal states for the axis/spindle are reset.
● NC: The axis-specific machine data, which become effective at reset, become active.
Note
In conjunction with a channel reset, no axis-specific machine data is active for axes
controlled from the PLC.
● NC confirms the execution:
– DB31, ... DBX63.0 = 1 (reset executed)
– DB31, ... DBX63.2 = 0 (axis stop active)
– System variable $AA_SNGLAX_STAT = 1
● NC exits this operation.

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.
