Encoder signals The CC 6xxx can be connected with incremental 1 Vpp and absolute position
encoders with EnDat interface:
Use MP118.x to configure the position encoder inputs of the axes
Use MP119.x to configure the position encoder inputs of the spindles
When using an external Y cable, you need to deactivate the terminating
resistor of the position encoder input via MP118.x/MP119.x bit 1.
