Speed controller adaptation
Description
With the speed controller adaptation, any speed controller oscillation can be suppressed.
Two adaptation methods are available, namely free Kp_n adaptation and speed-dependent
Kp_n/Tn_n adaptation.
● Free Kp_n adaptation is also active for operation without an encoder - and is used in
operation with an encoder as an additional factor for speed-dependent Kp_n adaptation.
It is activated by connecting a signal source to p1455.
The setting is made using parameters p1456 to p1459.
● Speed-dependent Kp_n/Tn_n adaptation is only active in "operation with encoder" mode
and also affects the Tn_n value.
The Kp_n/Tn_n adaptation can be deactivated with p1400.5 = 0. As a consequence, the
dynamic reduction of the speed controller is deactivated.
