Parking A Machine Axis - Siemens SINUMERIK 840D sl Function Manual

Behavior when a working area limitation responds:
● The traversing motions of the geometry axes that are not affected are continued
● The affected geometry axis is stopped at the working area limit
Set initial setting
The specification of the working area limitation group that is to take effect at power up, reset
or end of the part program and start of the part program is performed channel-specifically via
the machine data:
MD20150 $MC_GCODE_RESET_VALUE[59] = <group>
The working area limitation group that is to take effect is still dependent on the setting in the
machine data:
MD20152 $MC_GCODE_RESET_MODE[59] = <mode>
<mode> Meaning

Parking a machine axis

If a machine axis is brought into the"Parking" state, then for this particular axis, no encoder
actual values are acquired, and all of the monitoring functions described in the preceding
sections (measuring system, standstill, clamping monitoring, etc.) are deactivated.
Activation / deactivation
Activation
"Parking" a machine axis activated by resetting the axis-specific NC/PLC interface signals for
the parameterized position measuring systems and the controller enable of the machine axis:
● DB31, ... DBX1.5 (position measuring system 1) = 0
● DB31, ... DBX1.6 (position measuring system 2) = 0
● DB31, ... DBX2.1 (controller enable) = 0
The encoder status of the position measuring system of the axis is then set to "Not referenced":
● DB31, ... DBX60.4 (referenced/synchronized, position measuring system 1) == 0
● DB31, ... DBX60.5 (referenced/synchronized, position measuring system 2) == 0
The following further NC/PLC interface signals are also reset:
● DB31, ... DBX61.5 (position controller active) == 0
● DB31, ... DBX61.6 (speed controller active) == 0
● DB31, ... DBX61.7 (current controller active) == 0
● DB31, ... DBX93.7 (pulses enabled) == 0
