Application Examples

The following are a few examples of the types of applications that are possible
by combining various features.
• Contact Input ® Programming ® Contact Output:
High-speed interrupt I/O processing or IORF instruction execution can be
used to refresh outputs whenever required.
• Pulse Input ® Program ® Pulse Output for CS1W-HCP22-V1
• An Electronic Cam Mode can be used to perform a specific absolute
positioning operation and speed change for the rotational angle or cur-
rent position of a workpiece. For example, the encoder output from a
main control axis can be input to the high-speed counter, and a spec-
ified 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 instruction can also be used to change the num-
ber of output pulses (target position) based on the defined value to
change the pulse output during operation.
• Speed control via a pulse output can be achieved in response to the
position 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 program 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 in-
put, and then programming a one-shot pulse output using the STIM in-
struction in the interrupt program.
• Pulse Input ® Program ® Analog Output for CS1W-HCA22-V1
• Simple positioning with an analog output can be achieved with an in-
verter and motor. This is achieved by combining an interrupt for the
present value of a pulse input, and then programming a stepped ana-
log 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
workpiece. 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 com-
bining a timer instruction with a slopped analog output using the ACC
instruction.
• Torque control (Clamping in molding applications, transfer control in injec-
tion-molding applications) (CS1W-HCA12-V1 only) ® Position control ®
pressure control (speed control and torque limit) ® position control
• Using this unit with a servo driver of an analog input type and a pres-
sure sensor enables the control as described below. Note that the ser-
vo driver (W series manufactured by OMRON in the example) is to be
in the "speed control" mode.
