Acquisition Control
Note that if this interpretation of direction is not as you desire, you could change it by moving the
Phase A output from the shaft encoder to input line 2 and the Phase B output to input line 1.
Shaft Encoder Module Parameters
There are several parameters and commands associated with the shaft encoder module. The list
below describes the parameters and commands and explains how they influence the operation of
the module.

The Shaft Encoder Module Counter Mode parameter controls the tick counter on the shaft
encoder module. The tick counter counts the number of ticks that have been received by the
module from the shaft encoder. This parameter has two possible values: Follow Direction and
Ignore Direction.
If the mode is set to Follow Direction, the counter will increment when the module receives
forward ticks from the shaft encoder and will decrement when it receives reverse ticks.
If the mode is set to Ignore Direction, the counter will increment when it receives either forward
ticks or reverse ticks.

The Shaft Encoder Module Counter parameter indicates the current value of the tick counter.
This is a read only parameter.

The Shaft Encoder Counter Module Max parameter sets the maximum value for the tick
counter. The minimum value for this parameter is 0 and the maximum is 32767.
If the counter is incrementing and it reaches the max, it will roll over to 0. That is:
Max + 1 = 0
If the counter is decrementing and it reaches 0, it will roll back to the max. That is:
0 - 1 = Max

The Shaft Encoder Module Counter Reset command resets the tick counter count to 0.

The Shaft Encoder Module Mode parameter controls the behavior of the "reverse counter"
that is built into the module. This parameter has two possible values: Any Direction and
Forward Only. For more information about this parameter, see the detailed description of the
reverse counter that appears later in this section.

The Shaft Encoder Module Reverse Counter Max parameter sets a maximum value for the
module’s "reverse counter". The minimum value for this parameter is 0 and the maximum is
32767. For more information about this parameter, see the detailed description of the reverse
counter that appears later in this section.

The Shaft Encoder Module Reverse Counter Reset command resets the reverse counter
count to 0 and informs the software module that the current direction of conveyor movement is
forward. For more information about this parameter, see the detailed description of the reverse
counter that appears later in this section.
