Relative positioning
In order to implement a relative positioning, the input RFGPHx−REL−SEL must be set to HIGH. This
serves to process the value at RFGPH2−SET as feed".
This means, the profile generator continues running by the position value applied at RFGPH2−PHIN.
Condition: Mode with limit stop" must be selected!

Relative positioning
l
With RFGPH2−STOP = HIGH the positioning process is only interrupted. With RFGPH2−STOP
= LOW the residual path is travelled.
l
The position value refers to the last start point if
– the position value at input RFGPH2−SET changes during the positioning process or
– the input RFGPH2−STOP changes from LOW HIGH.
l The positioning process is completed when the target position has been reached. The level at
output RFGPH2−RFG−I=0 is HIGH.
