To achieve this in which variable i have to link this variable. Attachment FEED ROLL POSITION IMAGE.PNG (28 Downloads)

If not the the new velocity can't be active, the parameters in the command only used with the command start. To modify the velocity during the execution of the command you can use the override.velocity variable on the TO. here you can specifiy how many % of the commandvelocity should be used (default 100%) Regards Christoph
