Siemens SINAMICS S110 List Manual page 379

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.
p2575 BI: EPOS jerk limiting activation / Jerk limit act
SERVO_S110-CAN Can be changed: T
(EPOS),
Data type: Unsigned32 / Binary
SERVO_S110-DP
P-Group: Basic positioner
(EPOS),
Not for motor type: -
SERVO_S110-PN
(EPOS)
Min
-
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.

Description: Sets the modulo range for axes with modulo correction.
Dependency: Refer to: p2577
p2577 BI: EPOS modulo correction activation / Modulo corr act
SERVO_S110-CAN Can be changed: T
(EPOS),
Data type: Unsigned32 / Binary
SERVO_S110-DP
P-Group: Basic positioner
(EPOS),
Not for motor type: -
SERVO_S110-PN
(EPOS)
Min
-
Description: Sets the signal source to activate modulo correction.
Dependency: Refer to: p2576
Note: When the signal state changes at the binector input, this only becomes effective in the "ready to power-up" state.
Selecting modulo correction:
The current position setpoint in the modulo range is corrected. The position actual value differs from the position
setpoint by the following error and can also leave the modulo range.
De-selecting modulo correction:
It is based on the current position actual value.
