Figure 7-8 PI Controller Gain, I-Time and Error Value.
PI-SCMIN
Minimum scaling factor of the actual value. The setting
range is -999.9 to 999.9 %. The value of PI-SCMIN can be
higher than the value of PI-SCMAX. See the example A in
Figure 7-9. In this example, PI-SCMIN is 400 % and PI-
SCMAX is -300 %.
PI-SCMAX
Maximum scaling factor of the actual value. The setting
range is -999.9 to 999.9 %. See Figure 7-9 and Figure 7-10.
In this example B, 4 V is equivalent to 0 % and 8 V is equiv-
alent to 100 %. You can get the corresponding values for
parameters PI-SCMIN and PI-SCMAX from the straight line
in Figure 7-9. In the example B, PI-SCMIN is -100 % and PI-
SCMAX is 150 %.
