150 Programmable Controllers
Achieve More Flexible, More Precise Machines with Pulse I/O Control
SYSMAC CJ1M-CPU21/22/23
CJ1M-CPU21 (5-Kstep)
CJ1M-CPU22 (10-Kstep)
CJ1M-CPU23 (20-Kstep)
Pulse outputs: 100 kHz, 2 axes
Counters: Single-phase, 100 kHz,
2 counters or
Differential phases, 50 kHz,
2 counters
Interrupts: 4
The above can all be used simultaneously.

Deceleration
Acceleration
Deceleration
Easily achieved with
special positioning
instruction (PLS2).
Positioning is also
possible with trapezoidal
control with different
acceleration and
deceleration times.
Positioning that does
not reach the target
speed is also possible
(triangular
control).
PCB Rack Positioning
PCB Conveyor Rail
Width Positioning
Fast startup times (the time from instruction execution to start of pulse
output): 46 µs minimum, 70 µs for trapezoidal acceleration/deceleration.

Changing Target Position during Positioning
(PLS2 and PLS2 Instructions)
Interrupt Feeding (ACC and PLS2 Instructions)
Speed control
(ACC)
Stop after output
of set number of
pulses
PLS2 executed.
Feed Control for
Packing Material
Positioning with Trapezoidal Acceleration/Deceleration
(PLS2 Instruction)
Origin Searches (ORG Instruction)
Origin searches are possible with one ORG instruction.
Even with servomotors, a differential-phase counter reset output
minimizes position deviations for origin searches.
The target position can
be changed even after
positioning has been
started.
Reversals (positioning
in the opposite
direction) are also
possible.

can be used to reduce
vibration in high-speed
positioning.

Duty ratio: 50.3% 22.1%
Fine-tune the opening/closing times of
the valve.
High-precision Variable Duty Ratio (PWM output)
Specify a duty ratio in 0.1% units.
