Observe the information about the parameters in Chapter "Function diagrams and parameters

(Page 485)".

A connector input is provided to enter reference point coordinates for all types of referencing.

This allows, e.g. changes/input via the higher-level controller. 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.

● 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)

● Referencing type selection (p2597)

● Absolute encoder adjustment (p2507)

Referencing of distance-coded zero marks is not supported.

Set reference point

The reference point can be set using a 0/1 edge at binector input p2596 (set reference point)

if no traversing commands are active and the actual position value is valid (p2658 = 1 signal).

A reference point can also be set for an intermediate stop.

The current actual position of the drive is set here as the reference point using the coordinates

specified by connector input p2598 (reference point coordinates). The setpoint (r2665) is

adjusted accordingly.

This function also uses actual position value correction for the position controller (p2512 and

p2513). Connector input p2598 is connected to adjustable parameter p2599 as standard. The

binector input is not effective for the traversing task being presently executed.
