3.19.5 21-4* Closed Loop 2 PID
21-40 Ext. 2 Normal/Inverse Control
Option: Function:
See parameter 21-20 Ext. 1 Normal/
Inverse Control for details.
[0] * Normal
[1] Inverse
21-41 Ext. 2 Proportional Gain
Range: Function:
0.01* [0 - 10 ] See parameter 21-21 Ext. 1 Propor-
tional Gain for details.
21-42 Ext. 2 Integral Time
Range: Function:
10000 s* [0.01 - 10000
s]
See parameter 21-22 Ext. 1 Integral
Time for details.
21-43 Ext. 2 Dierentation Time
Range: Function:
0 s* [0 - 10 s] See parameter 21-23 Ext. 1 Dieren-
tation Time for details.
21-44 Ext. 2 Dif. Gain Limit
Range: Function:
5* [1 - 50 ] See parameter 21-24 Ext. 1 Dif. Gain
Limit for details.
21-46 Ext. 2 On Reference Bandwidth
Range: Function:
5 %* [0 - 200 %] Enter the on-reference bandwidth.
When the PID control error (the
dierence between the reference
and the feedback) is less than the
value of this parameter, the on-
reference status bit is high.
