Controller optimization standard
Smooth, stable beha vior?
Increase stiffness (Obj. 2100.2)
Adapt control signal filter according to the setting
rule (see chapter “control signal filter /...”)
(if need s be, change attenua tion (Obj. 2100.3)
yes
no
Select speed jerk response in the setup window /
tab “parameter), select the size of the jerk and
define jerk.
Respect the setpoint speed and the actual speed
Increase control signal filter of speed control
(Obj. 2100.20)
Additional filtering required?
(e.g. in the event of loud noise )
yes
no

Please note that a stronge r filtering may destabilize
the control loop Please try to find a compromise
between the signal quality (filtering ) and the
controller speed (stiffness )

Stabilize controller with the aid of
:
•
Decrease stiffness (Obj. 2100.2)
•
or/also reduce filter 2 speed actual value
(Obj. 2100.10)
•
or/also increase attenua tion (Obj. 2100.3)
Further optimization necessary?
