Figure 4:Frequency/Digital Input Conguration tab
This tab allows the user to congure any of the
frequency input tabs.
Variables:
• Termination mode: This is where the combination
of pull-up and pull-down resistors is congured.
• 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 congured in Encoder Mode.
• Filter time constant: This is a low pass lter 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 xed 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
conguration of an individual input using the
termination mode value drop down selection.
The options are as follows:
