Description

YASKAWA CP-317/AI-01 – Analog Input Module for MP-2300/MP-2310 Motion Controller

Product Description
The YASKAWA CP-317/AI-01 is a specialized analog input expansion module designed for Yaskawa’s MP-2300 and MP-2310 series of motion controllers (often categorized as Machine Controllers). This module is not a standalone PLC CPU but a critical peripheral that expands the I/O capabilities of the main controller. The primary function of the YASKAWA CP-317/AI-01 is to convert external analog voltage signals into digital values that the MP-2000 series motion controller can process. This enables the sophisticated motion controller to monitor and react to analog process variables such as pressure, temperature, tension, or speed feedback from non-digital sources, integrating them seamlessly into high-performance motion sequences and machine logic.

Product Parameters

• Type: Analog Input Expansion Module.

• Compatible Controller: Yaskawa MP-2300S, MP-2300Siec, MP-2310 Machine Controllers.

• Mounting: Connects directly to the base unit (e.g., MP-2300) via a side expansion connector.

• Number of Channels: 2 analog input channels.

• Input Signal Type: Voltage input.

• Input Voltage Range: Typically 0 to ±10 V DC (specifics must be verified by manual).

• Resolution: High-resolution analog-to-digital conversion (e.g., 16-bit).

• Conversion Speed: High-speed sampling suitable for integration into fast motion control loops.

• Input Impedance: High impedance (e.g., 1 MΩ) to minimize loading on the signal source.

• Isolation: Photocoupler isolation between internal circuits and external I/O lines to protect the controller from noise and voltage spikes.

• Data Format: The digital value is stored in a signed 16-bit register in the controller’s memory for use in user programs.

Advantages and Features

• Seamless Motion & Process Integration: The YASKAWA CP-317/AI-01 allows Yaskawa’s high-performance motion controller to directly read analog process signals. This enables the creation of tightly integrated systems where motion profiles can be dynamically adjusted based on analog feedback (e.g., tension control in winding, pressure control in pressing).

• High-Speed, High-Resolution Performance: Designed to meet the demanding requirements of motion control applications, offering fast update rates and fine resolution necessary for precise closed-loop process regulation within a motion sequence.

• Compact and Integrated Design: As an official expansion module, it mounts directly to the controller without external power or complex wiring, saving panel space and ensuring reliable communication.

• Simplified System Architecture: Eliminates the need for an external analog input device and additional communication gateways, reducing complexity, cost, and potential points of failure.

• Native Programming Support: The module is fully supported within Yaskawa’s MPE720 (Machine Controller Programming Environment) software. The analog values are easily mapped to variables in the motion control program.

Application Cases in Various Fields

• Packaging Machinery: Monitoring analog pressure signals from fill level sensors or analog signals from product sensors to synchronize the motion of fillers, cappers, and labelers.

• Converting & Web Handling (Printing, Paper, Film): Reading analog tension transducer signals (0-10V) for precise closed-loop tension control of webs in winders, unwinders, and printing presses.

• Metal Forming & Pressing: Integrating analog pressure or force feedback from load cells into press brake or stamping press sequences for adaptive force control.

• Assembly & Testing: Using analog signals from force gauges or displacement sensors to perform precise force-controlled assembly or quality check operations.

Comparisons with Competing Products

• Competing Motion Controller Analog Modules (Mitsubishi, Beckhoff): Mitsubishi’s MELSEC motion controllers and Beckhoff’s EtherCAT system have their own analog input terminals. The YASKAWA CP-317/AI-01 is optimized for the electrical and software environment of the MP-2000 series.

• Standalone Analog Input Devices: Using a separate analog input device with Modbus or EtherNet/IP adds complexity, latency, and programming overhead compared to the direct, high-speed integration of the CP-317/AI-01.

• PLC-based Solutions with Analog Cards: A standard PLC with an analog card could read the signal, but coordinating it with high-speed, synchronized motion is more challenging than using the dedicated CP-317/AI-01 module within a unified motion controller platform.

Selection Suggestions and Precautions

1. Confirm Controller Compatibility: The YASKAWA CP-317/AI-01 is specifically for the MP-2300/MP-2310 series. It will not work with other Yaskawa families like the MP-3000 or traditional PLCs like the FA-M3.

2. Verify Voltage Range and Wiring: Confirm the exact input voltage range (likely ±10V) and wiring diagram. Ensure your sensor’s output signal matches this range. Using a 4-20mA sensor will require an external signal converter to 0-10V.

3. Plan for Noise Immunity: Analog signals are susceptible to noise. Use shielded, twisted-pair cables for all analog wiring. Connect the shield to the FG (Frame Ground) terminal on the module and ground it at one point only.

4. Programming and Scaling: Within MPE720, you must configure the input channels and write logic to scale the raw 16-bit digital value (e.g., -32768 to +32767) into meaningful engineering units (e.g., 0-100 N, 0-50 bar).

5. Check Available Expansion Slots: The MP-2300 base unit has a limited number of expansion module slots. Ensure you have a free slot and that the total power consumption of all modules does not exceed the base unit’s capacity.

6. Consider Signal Conditioning: For signals from sensors in noisy environments or with long cable runs, consider using additional signal conditioners or isolators even though the module itself has isolation.
