Yamaha KHY-M4570-015 I/O Head Board for YS12/YG12/YS100/YS88/MC-12

The Yamaha KHY-M4570-015 I/O Head Board is an electronic control board used in compatible SMT pick and place equipment. According to the supplied hardware manual, the KHY-M4570-0XX I/O HEAD BOARD ASSY family is designed to connect up to six KHN-M5802-XXX Servo Unit Assemblies. It supplies several DC voltage levels required by the control system and relays communication, digital input and digital output signals to connected servo units.

The hardware manual identifies YS12, YG12, YS100, YS88 and MC-12 as target machines. The board also contains dedicated interfaces for servo connections, digital inputs, digital outputs, analog signals, fan circuits, origin signals and other machine-control functions. Six onboard LEDs provide a convenient visual reference for checking power and system conditions during maintenance.

For replacement purchasing, customers should confirm the complete KHY-M4570-015 part number, installed machine model, PCB layout and connector arrangement before ordering.

Cause

An SMT placement machine depends on continuous communication between its controller, servo units, sensors, actuators and electrical systems. The I/O Head Board is positioned within this control architecture and handles several important electrical and signal functions.

After long operating periods, faults may appear because of electrical aging, contamination, connector problems, unstable power or issues in connected devices.

Common situations requiring inspection include:

An alarm involving input/output or servo operation does not necessarily mean the I/O board itself has failed.

The technician should also inspect wiring, connectors, servo units and power circuits before replacing the board.

Solution

A structured troubleshooting procedure can help determine whether the KHY-M4570-015 requires replacement.

1. Record the Machine Alarm

Identify the exact error information displayed by the equipment and determine when the fault occurs.

This provides the first reference for distinguishing between:

• Power failure
• Servo communication fault
• Input signal issue
• Output signal issue
• Peripheral-device failure
• Wiring or connector problem

2. Check the LED Indicators

The supplied hardware manual shows six board LEDs representing different electrical and system conditions.

Checking these LEDs can quickly indicate whether an important power rail or overall system status is abnormal.

3. Inspect External Connections

Check:

• Power connectors
• Servo connectors
• Signal cables
• Machine wiring
• Fan interfaces
• Peripheral devices

A board replacement may not solve the problem if the original fault is caused by another connected component.

4. Verify the Existing Board

Before ordering a replacement, compare:

KHY-M4570-015

with the number printed on the board currently installed in the machine.

The supplied manual covers the broader KHY-M4570-0XX family, so the complete suffix should always be verified.

Specifications

The above electrical and functional information is taken from the supplied KHY-M4570-0XX hardware manual.

Main Connector References

The connector diagram in the manual clearly shows dedicated control interfaces and six separate servo connections.

LED Status Reference

These indicators make the board easier to inspect during machine troubleshooting because technicians can quickly check several important power conditions without relying only on the machine alarm display.

Application

The KHY-M4570-015 is suitable for machine maintenance where the installed configuration matches the required board.

YS12 Pick and Place Machine

YS12 is listed among the target machines in the hardware manual. The board can be used as a maintenance replacement after confirming the installed part number and board revision.

YG12 Pick and Place Machine

For YG12 applications, customers should compare the complete board number and connector configuration before purchase.

YS100 SMT Machine

YS100 is another machine listed in the target-machine section of the supplied manual.

YS88 SMT Machine

The KHY-M4570-0XX board family is also identified for YS88 applications.

MC-12 Equipment

MC-12 appears in the same target-machine list and should likewise be matched by complete part number before replacement.

Typical Usage

How It Works

The I/O Head Board combines several machine-control functions into one electronic assembly.

Power Distribution

The manual states that the board supplies:

• DC1.5V
• DC3.3V
• DC5V
• DC15V
• 24V
• DC48V for motor operation

Different machine circuits require different voltage levels, so stable distribution is important for reliable operation.

Servo Connection

The board can connect six KHN-M5802-XXX Servo Unit Assemblies.

The board diagram identifies these interfaces as:

SERVO1, SERVO2, SERVO3, SERVO4, SERVO5 and SERVO6.

Signal Communication

The board relays communication signals between the control system and servo units.

A dedicated TXD/RXD interface is also shown in the hardware diagram.

Digital Input and Output

Two digital input and two digital output interface groups are shown:

DI0 / DI1

DO0 / DO1

These signals form part of the machine's electrical control process.

Additional Interfaces

The board also includes connections identified as:

AD0, AD1, EV0, EV1, OT, ORG, FAN1, FAN2 and +24VOUT.

This extensive interface arrangement makes the board an important part of the machine's control and signal distribution system.

How To Choose

Electronic boards should be selected by more than machine model alone.

1. Confirm the Complete Part Number

Your existing board should be checked for:

KHY-M4570-015

Do not select a replacement solely because it belongs to the KHY-M4570 family.

2. Confirm the Machine Model

Provide the complete equipment model:

• YS12
• YG12
• YS100
• YS88
• MC-12

3. Compare the Board Layout

Check:

• PCB dimensions
• Connector quantity
• Connector positions
• Servo interfaces
• DI/DO interfaces
• Mounting points
• Board labels

4. Provide Clear Photos

For accurate quotation and compatibility checking, provide:

5. Do Not Assume Family Interchangeability

The supplied documentation identifies the board family as KHY-M4570-0XX, but it does not provide a complete interchangeability list for all suffix versions.

Therefore, another KHY-M4570-0XX version should not automatically be considered a direct substitute for KHY-M4570-015.

FAQ
