9.4.7.2 Limitations
Description
The velocity, acceleration and deceleration can be limited and the software limit switches
and STOP cams set.
The following restrictions exist:
● Velocity profile limitations
–
Maximum speed (p2571)
– Maximum acceleration (p2572) / maximum delay (p2573)
● Traversing range limits
–
Software limit switches (p2578, p2579, p2580, p2581, p2582)
– Hardware limit switch (p2568, p2569, p2570)
● Jerk limit
–
Jerk limitation (p2574)
– Activation of jerk limitation (p2575)
Maximum velocity
The maximum velocity of an axis is defined using parameter p2571. The velocity should not
be set to be greater than the maximum speeds in r1084 and r1087.
The drive is limited to this velocity if a higher velocity is specified or programmed via the
override (p2646) for the reference point approach or is programmed in the traversing block.
