defaultMotionIn.velocity

DavidBrown Posts: 975 Rating: (9)	Suppose I want to run an axis 'velocity geared' to another axis. If I do not want to use the standard velocity gearing, but I want to program something in the servotask, would the following procedure correct : In the servotask I write a program like : axis2.defaultMotionIn.velocity := axis1.motionStateData.commandVelocity At start I enable both axes, if both axes respond enabled, I give speed or postion commands to axis1. Then I suppose axis 2 will follow axis 1 speed controlled?

If you will add a offset then write: axis1.motionStateData.commandVelocity + offset Regards Christoph
