Positioning module IMD20, IMD40
ACSetup programme
The maximum speed is determined internally and then limited to 95 %, in order to dispose of a good
reserve for the regulation.
Important:
If a current short circuit fault (fault number 13) occurs during the automatic determination
Pos
of the maximal velocity the user must reduce step by step the current limitation (in the main iq_Limit)
until the fault 13 does not occur anymore.
ition Controller dialogue box
The position controller is a PD controller with velocity feed forward. This is superimposed on the
velocity controller, i.e. the velocity controller has to be set first. A feed forward always leads to better
dynamics, but also to an following. Normally, the default values for he feed forward should be
applied.
For the test of the settings, a test signal is again available consisting of three impulses with different
signs. The ramp slope can be chosen
en the (previously determined) maximum acceleration
nd a maximum ramp (jump).
In order to be able to assess the settings, the display options speed and following error (control
betwe
a
deviation) are available.
