7.1 Counter Function
Count
For the direction distinction input, the
count signal is connected to the input
A signal. The count direction is
controlled by the level of the direction
signal of the input B signal.
When the input B signal is off, the
counter is incremented when the input
A signal rises or falls. When the input
B signal is on, the counter is
decremented.
In the individual input method, the
counter is incremented when the input
A signal rises or falls, and
decremented when the input B signal
rises or falls.
For the phase input, the input A signal
and input B signal of each counter are
connected to the phase A and phase
B of an encoder.
The count direction is determined by
the phase difference between phase
A and phase B. When phase A is
advanced by 90 degrees in electrical
angle compared to phase B, the count
value is incremented. When phase A
is delayed by 90 degrees in electrical
angle compared to phase B, the count
value is decremented.
