21-42 Ext. 2 Integral Time
Range: Function:
20 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 Dierentation 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:

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.
