FC 300 Programming Guide
Edge triggered pulse input counts number of
pulse flanks per sample time. This gives a higher
resolution at high frequencies, but is not as
precise at lower frequencies. Use this pulse
principle for encoders with very low resolution
(e.g. 30 ppr).
Time based pulse input measures the duration
between flanks. This gives a higher resolution at
lower frequencies, but is not as precise at higher
frequencies. This principle has a cut-off frequency
which makes it unsuited for encoders with very
low resolutions (e.g. 30 ppr) at low speeds.

When enabled, it inverts the resulting error
from the process PID controller. Available only
if "Configuration Mode" is set to "Surface
Winder", "Extended PID Speed OL" or
"Extended PID Speed CL".
When enabled, resets the I-part of the Process
PID controller. Equivalent to par. 7-40 Process
PID I-part Reset. Available only if "Configura-
tion Mode" is set to "Surface Winder",
"Extended PID Speed OL" or "Extended PID
Speed CL".
When enabled, enables the extended process
PID controller. Equivalent to par. 7-50 Process
PID Extended PID. Available only if "Configura-
tion Mode" is set "Extended PID Speed OL" or
"Extended PID Speed CL".
All Digital Inputs can be set to PTC Card 1 [80].
However, only one Digital Input must be set to
this choice.
