July 2013 6.8 The control loop 855
Machine type 1:
The machine is commissioned as usual until the k
v
factor is to be
determined.
Enter MP2602.x = 1 and MP2604.x = 0.
Increase the k
V
factor (MP1510.x) until you reach the oscillation limit.
Starting value:
Change MP2604.x until you have found the maximum k
V
factor (MP1510.x).
If you cannot find a maximum k
V
factor, use the default value in MP2604.x.
Starting value:
Increase MP2602.x until you have found a maximum k
V
factor (MP1510.x).
If the value found for MP2602.x is significantly greater than the starting
value (> factor 2), you should adjust MP2604.x again by enlarging and
reducing it to find the optimum value.
Machine type 2:
The machine is commissioned as usual until the k
V
factor is to be
determined.
Enter MP2602.x = 1 and MP2604.x = 0.
Increase the k
V
factor (MP1510.x) until you reach the oscillation limit.
Starting value:
Change MP2604.x, normally by reducing it, until the following error is at its
minimum.
MP2602.x IPC time constant T
