Wiring Example for High-speed Counter Input Terminals
Using a 24-VDC Open-collector Encoder
The following example shows the connections of an encoder with phase-A, phase-B, and phase-Z
inputs to high-speed counter 0.
Writing the Ladder Program
Execution
Program
Reference
Generating interrupts for the
high-speed counter PV (num-
ber of pulses) and perform
high-speed processing.
Specify interrupt tasks with CTBL
instructions.
Reading the high-speed
counter PV (number of
pulses).
Read the high-speed counter PV from
the Auxiliary Area and convert it to
position or length data using instruc-
tions or measure the length using con-
mparison instructions such as =, >,
and <.
Reading the high-speed
counter frequency (speed).
Execute a PRV instruction.
