ENDLESS POS, ENDLESS NEG
Using these tasks, the axis is accelerated to the specified velocity and is moved until one of
the following conditions is fulfilled:
● A software limit switch is reached.
● A STOP cam signal has been issued.
● The traversing range limit is reached.
● Motion is interrupted using control signal "no intermediate stop / intermediate stop"
(p2640).
● Motion is interrupted using control signal "do not reject traversing task / reject traversing
task" (p2641).
● An external block change is triggered (with the appropriate continuation condition).
The following parameters are relevant:
● p2616[x]: Block number
● p2618[x]: Velocity
● p2619[x]: Acceleration override
● p2623[x]: Task mode
All continuation conditions are possible.
JERK
Jerk limitation can be activated (command parameter = 1) or deactivated (task
parameter = 0) using the JERK task. The signal at the binector input p2575 "Active jerk
limitation" must be set to zero. The value parameterized in "jerk limit" (p2574) is the jerk limit.
A precise stop is always carried out here regardless of the parameterized continuation
condition of the task preceding the JERK task.
The following parameters are relevant:
● p2616[x]: Block number
● p2622[x]: Task parameter = 0 or 1
All continuation conditions are possible.
