Traversing blocks
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 order are effective during a block change, i.e. if:
● The appropriate traversing block number is selected using binector inputs p2625 to
● A block change is made in a sequence of traversing tasks.
● An external block change p2632 "External block change" is triggered.
Traversing blocks are parameterized using parameter sets that have a fixed structure:
● Traversing block number (p2616[0...63])
● Task (p2621[0...63])
● Motion parameters
● Task mode (p2623[0...63])

p2630 (block selection, bits 0...5) and started using the signal at binector input p2531
(activate traversing task).
Every traversing block must be assigned a traversing block number (in STARTER "No.").
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.
1: POSITIONING
2: FIXED ENDSTOP
3: ENDLESS_POS
4: ENDLESS_NEG
5: WAIT
6: GOTO
7: SET_O
8: RESET_O
9: JERK
– Target position or traversing distance (p2617[0...63])
– Velocity (p2618[0...63])
– Acceleration override (p2619[0...63])
– Deceleration override (p2620[0...63])
The execution of a traversing task can be influenced by parameter p2623 (task mode).
This is automatically written by programming the traversing blocks in STARTER.

– aaaa: Display/hide
0000: Block is not hidden
0001: Block is hidden
A hidden block cannot be selected binary-coded via binector inputs p2625 to p2630.
An alarm is output if you attempt to do so.
– bbbb: Continuation condition
0000, END: 0/1 edge at p2631
0001, CONTINUE_WITH_STOP:
The exact position parameterized in the block is approached (brake to standstill and
positioning window monitoring) before block processing can continue.
