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)

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)
