Signal filter factor Speed and acceleration are derived from the positioning
signal and filtered to improve the signal quality. If in practice
there is bad signal quality, e.g. due to electrical interferĆ
ence, filtering of the signal can be influenced by the signal
filter factor.
If filtering is too strong it may destabilize control.
Behaviour of the axis Factor
The drive tends towards instability (despite low
gain and good damping). Reduce
Noise" or loud valve noises (observe gain; this
may be too high). Increase
The positioning process is carried out quickly and
accurately, low valve noises. Optimal
