Kv Factor
Feedforward can only be turned on for ’Flying Cutoff’ or ’Slave Axis.’
With the Kv Factor, the position gain is defined. The Kv Factor determines
the position lag that would be calculated at maximum velocity.
Kv = 1 produces a position lag of 1 mm at a velocity of 1 m/min.
Input range: from 0.01 to 20.00
The Kv factor must be matched to the given mechanical conditions.
A Kv Factor that is too small reduces drive dynamics.
A Kv Factor that is too large causes the drive to become unstable.
To determine the optimal value, begin with Kv = 1.00.
