SINAMICS S List Manual (LH1), 07/2007
Note:
The maximum deceleration appears to exhibit jumps (without jerk).
"Traversing blocks" operating mode:
The programmed deceleration override (p2620) acts on the maximum deceleration.
"Direct setpoint input/MDI" mode:
The deceleration override is effective (p2645, 4000 hex = 100 %).
"Jog" and "search for reference" modes
No deceleration override is effective. The axis breaks with the maximum deceleration.
Description:
Sets the jerk limiting
Dependency:
Refer to: p2572, p2573, p2575
Note:
The jerk limiting is internally converted into a jerk time as follows:
Jerk time Tr = max(p2572, p2573) / p2574
The jerk time is internally limited to 1000 ms and is rounded-off to an integer multiple of the sampling time position-
ing (p0115[5]).
The jerk time is valid for the acceleration and deceleration phases also for unequal maximum acceleration (p2572)
and maximum deceleration (p2573).
For unequal maximum acceleration and maximum deceleration, the motion is not optimal from a time perspective
as the jerk limit cannot be used for the lower of the two values.
If, in the traversing profile, the acceleration time without jerk limiting is less than the jerk time Tr, then the motion
with jerk limiting is not optimum from a time perspective.
For traversing motion with a direct transition between acceleration and deceleration (i.e. jerk time is greater than the
constant velocity phase), jerk can increase up to twice the parameterized jerk.
CONTINUE_FLYING with direction reversal acts internally just like a CONTINUE_WITH_STOP without the "posi-
tion reached" being set. Without jerk limiting, this behavior can hardly be noticed as, when reversing, the position
setpoint is only kept at zero for one interpolator clock cycle.
For block change enable CONTINUE_WITH_STOP, jerk limiting results in a longer delay time.
Description:
Sets the signal source to activate the jerk limiting.
Activating/de-activating:
- using BI: p2575 = 1 signal or 0 signal.
- using the command JERK in the traversing block (only for BI: p2575 = 0 signal).
Dependency:
Refer to: p2574
Note:
A change of the signal state at the binector input is only accepted at zero speed.
