Absolute positioning
INFORMATION
After reaching the reference cam, positioning starts immediately to the selected tar-
get position (P1...P4).
The "Absolute positioning" operating mode is suitable for applications with up to
4
dif-
ferent positions that are cyclically controlled. The different position values are stored
locally in the drive. The values are set during startup via the engineering interface. Op-
erational control of the 4 positions is coded via 2 digital inputs.
In this operating mode, parameter KP_H must have a value of
>
0. Perform a refer-
ence travel (homing) every time the 24 V control voltage is switched off and on again.
Function after switching on the 24 V control voltage (reference value is not set).
