Figure 4:Frequency/Digital Input Configuration tab
This tab allows the user to configure any of the
frequency input tabs.
Variables:
•
Termination mode: This is where the combination
of pull-up and pull-down resistors is configured.
•
DIN debounce: This is the time value used to
debounce mechanical switches that would
otherwise trigger the input multiple times
when closed.
•
DIN rising threshold: This is the rising threshold
voltage for digital inputs (effects the digital
value only).
•
DIN falling threshold: This is the falling threshold
voltage for digital inputs (effects the digital
value only).
•
Phase channel pair: This selects channel pair used
for phase comparison (1 is 1st pair, 2nd is 2nd pair,
etc.). When configured in Encoder Mode.
•
Filter time constant: This is a low pass filter time
constant that is used on the following values:
frequency, duty cycle, and voltage measurements.
•
Over-voltage limit: This is the upper limit used for
the over-voltage fault.
•
Lower-voltage limit: This is the lower voltage limit
used for the under-voltage fault.
•
Frequency rising edge threshold: This enables
either the adaptive (peak-detect) rising edge
voltage threshold or the fixed 2.2 V threshold for
the frequency circuit.
•
Frequency falling edge threshold: This enables
either 1.0 V or 0 V as the falling edge voltage
threshold for the frequency circuit.
This tab enables the programmer to change the
configuration of an individual input using the
termination mode value drop down selection.
The options are as follows:
