The YASKAWA PS-01 (often identified by the part number JEPMC-PS210) is a specialized Power Supply Module specifically designed for the MP920 Machine Controller series.

It serves as the primary power source for the controller’s backplane, providing the necessary DC voltages to run the CPU and various I/O or motion modules.

1. Introduction

The PS-01 is a rack-mounted power supply unit that converts standard AC input into stabilized DC power for the MP920 system.

As part of Yaskawa’s “Machine Controller” ecosystem, it is built to withstand the rigorous electrical demands of high-speed motion control and multi-axis synchronization.

It is a critical component; without it, the logic and communication modules in the rack cannot function.

3. Product Advantages and Features

High Stability: Provides extremely clean DC power to prevent logic errors in high-speed motion CPUs.

Built-in Protection: Features overvoltage and overcurrent protection to safeguard expensive CPU and Motion modules from electrical surges.

Industrial Grade: Designed for 24/7 operation in factory environments with high vibration and temperature fluctuations.

Modular Design: Easy to install or replace within the MP920 rack system, minimizing downtime during maintenance.

Diagnostic LEDs: Includes front-facing indicators for instant troubleshooting of the power status.

4. Application Cases

The PS-01 is used wherever an MP920 controller is deployed, typically in:

Multi-Axis CNC Machines: Providing logic power for complex tool-path calculations.

Automated Assembly Lines: Powering the “brain” of a system controlling dozens of Sigma-series servos.

Packaging Systems: Used in high-speed wrapping and filling machines requiring precise timing.

Semiconductor Equipment: Found in wafer handling and cleanroom robotics controllers.

5. Related & Other Models in the Same Series

The PS-01 belongs to the MP920 Controller family. Depending on the size of the rack and the specific controller generation, you may encounter these related modules:

PS-02: A higher-capacity power supply for larger MP920 rack configurations.

CPU-01 / CPU-02: The primary logic modules that sit alongside the PS-01.

SVA-01: Servo Axis modules used in the same rack for analog/pulse control.

LIO-01 / LIO-02: Local I/O modules powered by the backplane DC bus provided by the PS-01.

JEPMC-PS200: A variant or predecessor model used in older machine controller setups.

Maintenance Tip

Since the PS-01 is an older (legacy) module, the internal electrolytic capacitors can age over time. If your controller is experiencing intermittent “reboots” or logic errors, the PS-01 is often the first component to check for voltage stability.
