13.7.3.8 FB 805 - MC_MoveVelocity - drive axis with constant velocity
An overview of the drive systems, which can be controlled with this block
can be found here:
Ä
Chap. 13.7.1 ‘Overview’ page 542
With MC_MoveVelocity the axis is driven with a constant velocity. With the parameters
Velocity, Acceleration and Deceleration the dynamic behavior can be determined during
the movement.
