Features
● Reference point offset (p2600)
● Reversing cams (p2613, p2614)
● Reference cam (p2612)
● Binector input start (p2595)
● Binector input setting (p2596)
● Velocity override (p2646)

NOTICE
Referencing distance-coded zero marks is not supported.
Description
After a machine has been powered-up, for positioning, the absolute dimension reference
must be established to the machine zero. This operation is known as referencing.
The following referencing types are possible:
● Setting the reference point (all encoder types)
● Incremental encoder
Active referencing (reference point approach (p2597 = 0)):
– Reference cams and encoder zero mark (p2607 = 1)
– Encoder zero mark (p0495 = 0)
– External zero mark (p0495 ≠ 0)
