•
Up to 32 user-set words in the CPU Unit can be shared with LR Area words
in the Customizable Counter Unit.
•
External interrupt tasks in the CPU Unit can be executed by programming the
MCRO instruction in the Customizable Counter Unit. The Customizable
Counter Unit can thus activate programming in the CPU Unit depending on the
control status of the Customizable Counter Unit to synchronize processing
with other Units.
1-1-2 Application Examples
The following are a few examples of the types of applications that are possible by
combining various features.

Pulse Output for CS1W-HCP22
•
An Electronic Cam Mode can be used to perform a specific absolute posi-
tioning operation and speed change for the rotational angle or current
position of a workpiece. For example, the encoder output from a main con-
trol axis can be input to the high-speed counter, and a specified movement
for a target position (number of output pulses) for the followup axis can be
defined using linear approximation with the APR instruction. The PULS in-
struction can also be used to change the number of output pulses (target
position) based on the defined value to change the pulse output during op-
eration.
•
Speed control via a pulse output can be achieved in response to the posi-
tion of a workpiece. The present value of either a high-speed counter or
pulse output can be used with a target value interrupt for an interrupt pro-
gram that contains an instruction to change the frequency, i.e., SPED or
ACC.
•
High-speed processing, such as for coating or valve control, can be
achieved for a fast-moving object by outputting a one-shot output pulse
with a minimum unit of 0.01 ms from a specified position. This is achieved
by combining an interrupt for the present value of a pulse input, and then
programming a one-shot pulse output using the STIM instruction in the in-
terrupt program.

Analog Output for CS1W-HCA22
•
Simple positioning with an analog output can be achieved with an inverter
and motor. This is achieved by combining an interrupt for the present value
of a pulse input, and then programming a stepped analog output using the
SPED instruction or a slopped analog output using the ACC instruction in
the interrupt program.
•
Trapezoid torque control with an analog output for the position of a work-
piece. This is achieved by combining an interrupt for the present value of a
pulse input, and then programming a slopped analog output using the
ACC instruction in the interrupt program.
•
Trapezoid analog output for a specified time can be achieved by combin-
ing a timer instruction with a slopped analog output using the ACC instruc-
tion.
