8.2.2 Indexed Stop Position
The indexed stop position can be chosen by programming using a value in deg/10000.
Address C must be declared in P9 and P1 (modulo).
If no value is programmed, the value zero is taken as default.
A value for the indexed stop position is programmed:
- with the C address for a lathe group,
- with the EC address for a milling machine group.
Spindles
The spindle origin offset is defined by parameter P42. This parameter contains an angular offset (expressed in the
internal measurement units).
It is taken into account in an indexing.
P42 = Offset (in degrees) x 4096/360
Stopping in position is achieved by a symmetric servo-loop allowing the use of reversible servo-drives.
Example of Indexed Stop
For a lathe M19C (stop on spindle zero pulse)
M19C45 (stop at 45 degrees)
For a milling machine M19EC (stop on spindle zero pulse).
8.2.3 Indexed Stopping Condition
The stop is declared complete when:
- the absolute value of the position error is less than the in-position window defined by parameter P44,
- the spindle speed is considered sufficiently low (less than 3/4096 rev/sample).
The in-position window is defined by parameter P44 (expressed in internal measurement units).
