Omron PLC CJ-series CJ2M Pulse I/O Modules CJ2M-MD211 CJ2M-MD212

Pulse Inputs

Input method: Line-driver input or 24-VDC input (selected by wiring)

Normal Inputs

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

Input signal minimum ON pulse width: 30 ms

High-speed Counter Inputs

Input method: Differential-phase (´4) pulses, pulse + direction, up/down pulses, or increment pulse Maximum response frequency: 50 kHz for differential 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 software reset Control method: Target-value comparison or range comparison Gate function: Supported

Pulse Outputs

Output method: Sinking or sourcing transistor outputs (The method is determined by Pulse I/O Module model.)

Normal Outputs

Pulse Outputs

Output method: CW/CCW or pulse + direction (The method is determined by the I/O wiring and the instructions used in the ladder program.)

Output frequency: 1 pps to 100 kpps (in increments of 1 pps)

Output Mode: Continuous mode (for speed control) or independent mode (for position control) 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

Output frequency: 0.1 to 6,553.5 Hz (in 0.1-Hz increments) or 1 to 32,800 Hz (in 1-Hz increments) Duty ratio: 0.0% to 100.0% (in 0.1% increments)
