Yaskawa Control Boards Index | CPU, I/O, Servo & Safety Catalog

The Yaskawa control boards are the heart of all Yaskawa Motoman robot controllers, including the YRC1000, NX100, NX200, and GP-series.
These boards manage motion control, I/O communication, servo coordination, safety monitoring, and human-machine interface operations, making them critical for continuous industrial automation.

This index provides a structured overview of the main control board categories, typical part numbers, failure symptoms, and replacement guidance for Yaskawa robots.

Why Control Boards Matter

Control boards handle the "brain" and "nervous system" of your robot. Board failures are often the root cause of:

• Robot downtime and production stoppages.
• Servo or axis errors preventing motion.
• Communication failures between the controller, robot, and PLC.

Having a comprehensive parts index allows maintenance teams to quickly identify and replace faulty boards.

Main Categories of Yaskawa Control Boards

1. CPU & Main Logic Boards

Responsible for robot program execution, motion planning, and system management.

Below are typical CPU and main logic boards used in YRC1000, NX100, and NX200 controllers.

• Symptoms of failure: Controller fails to boot, program execution errors, system freezes.

2. Servo Communication & Amplifier Interface Boards

Manages high-speed communication between the controller and the servo drives.

• Symptoms of failure: Axis servo alarms, communication errors, loss of motion control.

3. Digital / Analog I/O Boards

• Symptoms of failure: Sensors/actuators not responding, PLC communication errors.

4. Fieldbus & Network Interface Boards

Symptoms of failure: Network communication drops, fieldbus device errors.

5. Safety & Relay Boards

Symptoms of failure: E-Stop not responding, unexpected motion lockouts.

6. Power Supply & Backup Boards

Symptoms: Controller wont power on, Random shutdowns or resets, Voltage or temperature alarms

FAQ C Yaskawa Control Boards

Q1: Can YRC1000 boards be used in NX100 or NX200 controllers?

A: No. Each controller generation uses unique architecture, firmware, and connectors; boards must match the controller model.

Q2: Which control boards fail most often?

A: Servo communication, I/O, and power supply boards are most frequently replaced due to industrial load and wear.

Q3: Are refurbished boards reliable?

A: Yes, when tested for functionality, communication, and safety compliance, refurbished boards provide a cost-effective solution.

Q4: How do I identify the correct board for replacement?

A: Always verify the board part number printed on the board and cross-reference with the robot series and controller firmware.
