Integrator KI
 Increase Kl (2200.37/2260.21), so that the following error becomes minimal and
the axis does not overshoot.
 Value will be preassigned by the configuration.
 Set inner window (2200.30) so that the axis does not readjust constantly (only
sensible larger than feedback resolution!)
 Set outer window (2200.31) so that possible overshoot is reduced.
 Limit maximum I term (2200.32 and 2200.33).
 Check settings at 50% Vmax and reduce if needs be.
 Check settings at Vmax and reduce if needs be.
Speed feedback
The feedback of the speed can increase the natural frequency, i.e. the dynamic of
the hydraulic drive.
Prerequisite:
Speed filter set correctly ( Filter for Speed and Acceleration actual value (see
page 142))
 Increase speed feedback (2100.13) at lowest speed up to the stability limit.
 Check settings at 50% Vmax and reduce if needs be.
 Check settings at Vmax and reduce if needs be.
Acceleration feedback
The feedback of the acceleration can dampen the hydraulic drive, i.e. reduce the
oscillation tendency.
Prerequisite:
Acceleration filter set correctly ( Filter for Speed and Acceleration actual value
(see page 142))
 Increase acceleration feedback (2100.14) at lowest speed up to the stability limit.
 Check settings at 50% Vmax and reduce if needs be.
 Check settings at Vmax and reduce if needs be.
Feedforwards (advanced)
In this chapter you can read about:
Speed feedforward (advanced) ....................................................................................... 144
Acceleration feedforward (advanced) .............................................................................. 145
The control behavior of the control can be adapted to the application via the
feedforward (in the optimization tree under feedforward main axis)
The following error can be minimized at movement with constant speed via the
feedforward without negative effect on the stability of the control.
Attention:
Feedforward controls may cause an overshoot over the target position!
Speed feedforward (advanced)
 Reduce speed feedforward (2010.13) at lowest speed until the following error is
minimized.
 Check settings at 50% Vmax and reduce if needs be.
 Check settings at Vmax and reduce if needs be.
