Abort function: The deceleration ramp is not as expected (corrected from V3.24.0)

Corrected from:

L_TB2P_TechModulesBasic 3.24.0.31

L_TF2P_TechModulesFollowingPositioning 3.24.0.28

L_TS2P_TechModulesSynchronizingCamming 3.24.0.27

Response of the new version:

TM Tablepositioning: In case of abort during manual jog, the deceleration of manual jog takes effect.

TM SpeedControl: In case of abort during manual jog, the deceleration of manual jog takes effect.

TM FlexCam: During the descent of the "CAMMING" cam, the Halt deceleration takes effect in the event of an abort.
TM CrossCutter: During the execution of the crosscutter functions (ACC_DEC_SYNC, HOLD_IN_PARK_POS, CUTTING_DONE, CUTTING), the Halt deceleration takes effect at Abort.
TM FlyingSaw: During the SAW_IN_PROCESS state, the SyncDec deceleration and SyncJerk jerk take effect on abort.

TM SyncPosBase: During "ACC_DEC_SYNC, SYNCHRONISED, BASEVELOCITY ", the "scPar.lrSyncDec" deceleration and "scPar.lrSyncJerk" jerk take effect at Abort.

TM SyncAndCorrection: During "ACC_DEC_SYNC, SYNCHRONISED, BASEVELOCITY ", the "scPar.lrSyncDec" deceleration and "scPar.lrSyncJerk" jerk take effect in case of abort.

TM ElectronicGearbox: During "ACC_DEC_SYNC, SYNCHRONISED, BASEVELOCITY ", the "scPar.lrSyncDec" deceleration and "scPar.lrSyncJerk" jerk have an effect on Abort.

What happens?

The deceleration ramp when activating the abortion function does not meet expectations.

When does the behaviour occur?

In the TM TablePositioning, the deceleration lrDec is effective in case of abort during manual operation.

In the TM SpeedControl, the deceleration of the last selected SpeedProfile takes effect in case of abort during manual driving.

The technology functions of the TMs FlexCam, CrossCutter, FlyingSaw, SyncPosBase, SyncAndCorrection and ElectronicGearbox are aborted at Abort with the deceleration value lrDec.

It is expected that an abort will occur with the deceleration ramp of the currently active function. If the function does not have any deceleration parameter, use the HALT deceleration.

Which products are affected?

Servo-Inverter i950 with the TA Sync And Correction (0x4000:0 = [41])

Short-term measures:

Abort the functions via a HALT request.
