Description
The Omron CJ1W-NC113 is a Position Control Unit (PCU) for the CJ-series PLC platform, designed to perform high-precision 2-axis (or 1-axis, model-dependent) servo positioning control via MECHATROLINK-II or pulse-train interface (depending on version — NC113 is typically a pulse-output type positioning unit). It offloads motion profiling (linear/speed-change/continuous path) from the CPU, enabling synchronized moves, homing, and interpolation without burdening the ladder scan. The unit connects directly to Omron G-Series / R-Series servo drives or accepts step/dir signals to third-party drives with appropriate interface.
Key Features
- Control Axes: 1 or 2 axes (CJ1W-NC113 = 2-axis pulse-type positioning unit for CJ rack).
- Command Interface: Pulse train output (CW/CCW or Pulse+Dir, up to 500 kHz typical) to servo amplifiers.
- Motion Functions: Absolute/Incremental positioning, Linear/Continuous path, Speed control, Homing (multiple methods), Interrupt feed, Acceleration/Deceleration selectable (trapezoidal/S-curve).
- Buffer Memory: Stores up to 100 positioning sequences per axis (dependent on CPU free memory / Unit Settings).
- Communication with CPU: Via CJ backplane bus — commands issued by ladder (PMOV / PABS / etc.) or via CX-Programmer Motion Tool.
- Compatibility: Works with CJ-series CPUs (CJ1M, CJ2M/H, CJ1G-H, etc.) — occupies one I/O slot.
- Country of Origin: Japan
Technical Specifications (CJ1W-NC113)
Parameter | Specification |
|---|---|
Model | CJ1W-NC113 (Omron CJ-series Position Control Unit) |
Number of Controlled Axes | 2 axes (independent or interpolated linear — 2-axis linear interpolation supported on some FW) |
Control Method | Pulse output (CW/CCW or PULSE+DIR) |
Max. Pulse Output Frequency | 500 kHz (differential line driver) |
Output Format | Open-collector or Line Driver (check your servo amp’s input — typically 5V differential line driver on NC113) |
Home Search | Multiple methods (near dog / decelerate dog / limit switch / Z-phase capture) |
Accel / Decel Types | Trapezoidal & S-curve (selectable per move) |
Positioning Data | Up to 100 patterns/axis stored in unit’s buffer (called by DM number or direct command) |
Backplane Current Draw | Approx. 350 mA from 5V backplane bus |
External Connections | 40-pin flat cable connector (CN1) — typically via Omron CIF-105 breakout cable to terminal block or direct to drive |
Mounting | CJ-series PLC rack (right-side expansion from CPU or expansion rack) |
Dimensions (W×H×D) | 31 mm × 90 mm × 65 mm (standard CJ module width) |
Weight | Approx. 0.1 kg |
Standards | CE, UL, cULus, KC, RoHS |
💡 Important Notes:
Breakout Cable Needed: CJ1W-NC113 uses a 40-pin micro-ribbon connector — you’ll need CIF-105 (40-pin to screw terminal block) or custom cable to wire to your servo amplifiers. Servo Compatibility: Output is 5V differential line driver pulse — verify your servo drive accepts 5V line-driver inputs (most modern ones do; older may need level conversion). CPU Selection: Ensure your CJ CPU has enough DM area & instruction set to support motion commands (CJ1M/CJ2M-H/ CJ2H recommended for complex motion). Not a Motion Controller: This is a positioning unit, NOT a full multi-axis interpolator like NJ/NX Motion — best for 1–2 axis independent or simple 2-axis linear interpolation.
