Spindle measuring systems

Encoder matching
When parameterizing the measuring systems of spindles, the same conditions apply as for
parameterization of the measuring systems of rotary axes. This multiple is 2048.
For incremental measuring systems see Chapter "Parameterization of incremental
measuring systems".
For absolute measuring systems see Chapter "Parameterization of absolute measuring
systems".
NOTICE
If the motor encoder is used for actual-value sensing, the encoder matching data must be
entered in the machine data for each individual gear stage if several gear stages are
present.
Pulse multiplication factor
The maximum multiplication of the appropriate drive is always used as the multiplication of
the increments.
Examples of encoder adaptation
IBN CNC: NCK, PLC, drive
