Positioning modes

Depending on the traversing range/application, you can select between different positioning mo-

des which are described in the below table.

dwJerkMode

DWORD

From library V02.05.xx.xx

S-ramp mode

• Will be supported as of controller software version V5.0.

With software versions < V5.0, this input has no function.

0 Second S-ramp time is not active.

• The dnJerk S-ramp time is used for the acceleration and decelera-

tion phase.

1 Second S-ramp time is active for deceleration.

• The dnJerk S-ramp time is only used for the acceleration phase.

• For the deceleration phase, however, the second dn2ndJerk S-

ramp time is used.

dn2ndJerk

DINT

From library V02.05.xx.xx

Second S-ramp time in [ms]

• Will be supported as of controller software version V5.0.

With software versions < V5.0, this input has no function.

• The second S-ramp time is only used for S-ramp mode "1" for the deceleration

phase.

Note!

For absolute positioning, the home position must be known!

• If an absolute positioning process (positioning modes 1 ... 2 and 11 ... 16) is started alt-

hough the home position is not known, an error message occurs.

• In this case a programming error has occurred and the program flow must be reset.
• If the error only occurs in a sequence profile, the last valid deceleration is used to

decelerate the drive to standstill.

The modulo positioning modes may involve reversing processes!

• If a modulo positioning process (positioning modes 11 ... 16) is started at an initial

speed other than zero, the target position may be overtravelled and a reversing pro-

cess may follow, depending on the selected deceleration / S-ramp time parameters.

This would also cause e.g. counter-clockwise rotation in the "Absolute CW (modulo)"

positioning mode.
