Detailed Description
2.3 Axis/spindle service display
"Referenced" status display
Status display for reference point approach (axis).
Bit0=Status 0:
Bit0=Status 1:
Bit1=Status 0:
Bit1=Status 1:
Depending on machine data
MD34110 $MA_REFP_CYCLE_NR
and
MD20700 $MC_REFP_NC_START_LOCK
Display corresponds to
IS "Referenced/synchronized" 1 or 2 (DB31, ... DBX60.4 and 60.5).
References: /FB1/, R1, "Reference Point Approach"
QEC learning active
Indicates whether or not the learning process for quadrant error compensation for the axis is
active.
Fixed stop reached
Indicates whether or not the axis has fulfilled the conditions for "Fixed stop reached" when
the "Travel to fixed stop" function is active (IS DB31..., DBX62.5)
References: /FB/, F1, Travel to Fixed Stop
Torque limitation value
Indicates the value programmed by means of
FXST[x] or
SD43510 $SA_FIXED_STOP_TORQUE
or the value defined with machine datum:
MD37010 $MA_FIXED_STOP_TORQUE_DEF
for the clamping torque for "Travel to fixed stop".
Unit: % of maximum torque
References: /FB/, F1, Travel to Fixed Stop
Safe actual position of the axis
Displays the current actual axis position that has been measured via the NC. This actual
position should correspond in value to "Safe actual position of drive".

The machine axis is not cross-referenced using position measurement system 1
or 2.
The machine axis has reached the reference point (incremental measuring
system) and/or target point (length measuring system with distance coded
reference marks) during reference point approach.
No obligation to cross-ref. (NC start possible without cross-ref. this axis)
There is no obligation to cross-reference for the NC start.
