7.3.6.3 Referencing
Features
● Reference point offset (p2600)
● Reversing cams (p2613, p2614)
● Reference cam (p2612)
● Binector input start (p2595)
● Binector input setting (p2596)
● Velocity override (p2646)
● Reference point coordinate (p2598, p2599)
● Selecting the referencing type (p2597)
● Absolute encoder adjustment (p2507)
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 or p0494 = 0)
*)
– External zero mark (p0495 ≠ 0 or p0494 ≠ 0)
*)
● Flying referencing (passive (p2597 = 1))
● Absolute encoder
– Absolute encoder adjustment
– Flying referencing (passive (p2597 = 1))
A connector input is provided for all referencing types to input the reference point coordinate;
this allows, e.g. the change/input via the higher-level control. However, to permanently enter
the reference point coordinate, an adjustable parameter for this quantity is also required. As
standard, this adjustable parameter p2599 is interconnected to connector input p2598.
