Behaviour of the axis Factor
The drive tends towards instability (tendency to
vibrate during positioning, up to continuous
vibration around the nominal position). Reduce
Bad positioning accuracy or high contouring fault
as well as long positioning time. Increase
The positioning process is carried out quickly and
accurately. Optimal
Permitted: 0.1 ... 10.0
Damping factor Damping is a measure for the transition behaviour of the
system from the actual to the nominal status, especially
when there are fast modifications to the nominal value. As a
rule the system should guarantee low−oscillation behaviour
with nominal value specifications and movement into the
target position without overswing.
By modifying the factor for damping, you can influence the
transition behaviour of the system.
Behaviour of the axis Factor
Bad positioning quality, nominal position is
approached only slowly (underswing). Reduce
The drive tends towards instability (tendency to
vibrate during positioning, up to continuous
vibration around the nominal position, heavy
overswing). Increase
The positioning process is carried out quickly and
accurately. Optimal
