Pulse I/O
*3
External interface --- CJ2M-MD211 or CJ2M-MD212 Pulse I/O Mod-
ule with 40-pin MIL connector
Pulse Inputs Can be used as normal inputs, interrupt inputs,
quick-response inputs, or high-speed counter
inputs. (Functions of each input must be
selected in the PLC Setup.)
Input method: Line-driver input or 24-VDC input
(selected by wiring)
Normal inputs 20 max. (10 per Pulse I/O Module)
Input constants: Set in the PLC Setup (0, 0.5,
1, 2, 4, 8, 16, or 32 ms). Default: 8 ms
Interrupt inputs and quick-
response inputs
8 max. (4 per Pulse I/O Module)
Input signal minimum ON pulse width: 30 µs
High-speed counter inputs 4 max. (2 per Pulse I/O Module)
Input method: Differential-phase (×4) pulses,
pulse + direction, up/down pulses, or increment
pulse
Maximum response frequency: 50 kHz for dif-
ferential phases or 100 kHz for single phase
Counting mode: Linear mode or circular (ring)
mode
Count value: 32 bits
Counter reset: Phase Z + software reset or soft-
ware reset
Control method: Target-value comparison or
range comparison
Gate function: Supported
Pulse Outputs Can be used as normal outputs, pulse outputs,
or PWM outputs. (Functions of each output
must be selected in the PLC Setup.)
Output method: Sinking or sourcing transistor
outputs (The method is determined by Pulse
I/O Module model.)
Normal outputs --- 12 max. (6 per Pulse I/O Module)
Pulse outputs 4 max. (2 per Pulse I/O Module)
Output method: CW/CCW or pulse + direction
(The method is determined by the I/O wiring
and the instructions used in the ladder pro-
gram.)
Output frequency: 1 pps to 100 kpps (in incre-
ments of 1 pps)
Output Mode: Continuous mode (for speed
control) or independent mode (for position con-
trol)
Output pulses: Relative coordinates: 0000 0000
to 7FFF FFFF hex (0 to 2,147,483,647 pulses)
Absolute coordinates: 8000 0000 to 7FFF
FFFF hex (−2,147,483,648 to 2,147,483,647)
Acceleration/deceleration curves: Linear or S-
curve
Origin search function: Supported
PWM outputs 4 max. (2 per Pulse I/O Module)
Output frequency: 0.1 to 6,553.5 Hz (in 0.1-Hz
increments) or 1 to 32,800 Hz (in 1-Hz incre-
ments)
Duty ratio: 0.0% to 100.0% (in 0.1% incre-
ments)
