12.13.4 Machine data for the function ”Setup mode division related”
NC MD 1104*:
Name : Number of divisions (ND)
Significance : Number of divisions per reference dimension
Standard value : 0
Input value limit : 1 ... 999
Reference system : ---
Input resolution : ---
Active : Every 100 ms
NC MD 1108*
Name : Division reference dimension (DRD)
Significance : Defines the reference to which the number of divisions
refers
Standard value : 0
Input value limit : Linear axis
Reference system : MS (Machine System)
Input resolution : units
Active : Every 100 ms
Note:
The rotary axis has an internal reference dimension of 360 degress according to the input
resolution. No inputs necessary.
When using the functions with chain magazines, a rotary axis may need several revolutions to
match one magazine revolution.
The division reference remains in this case, however, 360 degrees. The rotary axis or chain
magazines can be matched with the variable incremental weighting.
NC MD 1112*:
Name : Division offset
Significance : Relation between actual value= 0 and indexing position 1
Standard value : 0
Input value limit : Linear axis : +/ - 1 ... 99 999 999
Rotary axis : +/ - 360 degrees
Reference system : MS
Input resolution : units
Active : Every 100 ms
NC MD 564*, bit 3
Name : Actual values division related
Significance : The actual value is converted to an indexing position
(if the axis is an indexing axis).
Bit 3 = 0
: No conversion
Bit 3 = 1 : Conversion of actual value to indexing
position
Standard value : Bit 3 = 0 (for all axes)
Active : Every 100 ms
