Counting with Direction (cnt ud)
Rate Counter (rtE cnt)
Dual Counter (dUAL cnt)
Quadrature X 1 (QUAd1)
Quadrature X 2 (QUAd2)
Counter A will increment/decrement a count on every negative edge of the
input signal at Input A. The direction of the count is determined by the
logic state of Input B. A high level at Input B will cause Counter A to
increment one count. A low level will cause the unit to decrement a count.
The rate display is NOT affected by the logic state of Input B.
Counter A increments one count on every negative edge of the input signal
at Input B. The direction of the count is only positive. Input A is used
exclusively for the RATE INDICATOR.
Counter A increments one count on every negative edge of the input signal
at Input A. Counter B increments one count on every negative edge of the
input signal at Input B.
Note: This is the only mode in which Dual Counting is available.
Quadrature counting modes are primarily used in positioning and anti-
jitter applications. This mode requires two identical square wave signals
with one of them (QUAD) shifted 90° relative to the other (COUNT).
These two signals are processed by the CUB5 as follows.
Input A serves as the count and rate input, while Input B serves as the
quadrature input. For quadrature with single edge counting, the counter
will count in a positive direction when Input A is a negative going edge
and Input B is at a low level. The counter will count in a negative direction
when Input A is a positive going edge and Input B is at a low level. All
transitions on Input A are ignored when Input B is at a high level. These
logic rules provide the basis for anti-jitter operation which prevents false
counts from occurring due to back-lash, vibration, chatter, etc.
When two edge counting is used, the quadrature mode works the same as
single edge counting when Input B is low. When Input B is a high level,
counts at Input A are no longer ignored. Instead, the logic rules for Input
A are complimented, allowing both edges of Input A to be counted. This
doubles the effective resolution of the encoded input.

This mode takes the quadrature mode with two-edge counting one step
further. In quadrature times 4, both Input A and B serve as the count or
quadrature input, depending on their state. In one instance, Input A will
serve as the count input and Input B will serve as the quadrature input. In
another instance, Input A will be the quadrature input and Input B will be
the count input. This enables each edge, positive and negative going, of
both inputs, A and B, to be counted. This results in a resolution four times
greater than in the basic quadrature X1 mode. As in the other modes, Input
A is also used for the rate input.
This mode effectively sums count pulses that may simultaneously appear
on the two inputs. Counter A processes the pulses into a string of time
separated pulses so the internal counter will not lose any counts. Input A
serves as an add input (count increments) and Input B serves as an
additional add input (count increments).
