Traversing blocks

Function description

Up to 64 different traversing tasks can be saved. The maximum number is set using parameter

p2615 (maximum number of traversing tasks). All parameters which describe a traversing task

are effective during a block change if:

● The appropriate traversing block number is selected using binector inputs p2625 to p2630

(block selection, bits 0...5) and started using the signal at binector input p2631 (BI: EPOS

(activate traversing task).

● A block change is made in a sequence of traversing tasks.

● An external block change p2632 "External block change" is triggered.

Parameterize traversing blocks

Traversing blocks are parameterized using parameter sets that have a fixed structure:

● Traversing block number (p2616[0...63])

Each traversing block must have a traversing block number assigned to it. The traversing

blocks are executed in the sequence of the traversing block numbers. Numbers containing

the value "-1" are ignored so that the space can be reserved for subsequent traversing

blocks, for example.

● Task (p2621[0...63])

1: POSITIONING

2: FIXED ENDSTOP

3: ENDLESS_POS

4: ENDLESS_NEG

● Motion parameters

– Target position or traversing distance (p2617[0...63])

– Velocity (p2618[0...63])

– Acceleration override (p2619[0...63])

– Deceleration override (p2620[0...63])
