Special case: Parameter
[K speed loop filter]
(SFC)
not 0
This parameter must be reserved for specific applications that require a short response time (trajectory positioning or servo control).
- When set to 100 as described above the regulator is a “PI” type, without filtering of the speed reference.
- Settings between 0 and 100 will obtain an intermediate function between the settings below and those on the previous page.
Example: Setting with
[K speed loop filter]
(SFC)
= 100
•
[Speed prop. gain]
(SPG)
