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
