21-24 Ext. 1 Dif. Gain Limit
Range: Function:
5* [1 - 50 ] Set a limit for the dierentiator
gain (DG). The DG increases if there
are fast changes. Limit the DG to
obtain a pure dierentiator gain
when changes are slow and a
constant dierentiator gain when
quick changes occur.
21-26 Ext. 1 On Reference Bandwidth
Range: Function:
5 %* [0 - 200 %] Enter the on-reference bandwidth.
When the PID control error (the
dierence between the reference
and the feedback) is less than the
value of this parameter, the on-
reference status bit is high.
