Yaskawa CIMR-M5D2018 VS-626M5 Spindle Inverter

Yaskawa CIMR-M5D2018 VS-626M5 Spindle Inverter

The Yaskawa CIMR-M5D2018 is a high-performance AC Spindle Drive belonging to the Varispeed-626M5 (VS-626M5) series.

1 Unlike general-purpose industrial drives, this model is a vector-controlled inverter specifically engineered for machine tool spindle applications.

It is designed to work in tandem with a power regenerative converter (such as the VS-656MR5) to return energy to the power line during motor deceleration, significantly improving energy efficiency.

Technical Parameter Table

Product Advantages and Features

High-Precision Vector Control: Provides exceptional torque control and speed stability, which is critical for high-quality surface finishes in machining.

Energy Savings: When paired with a regenerative converter, it recycles braking energy back into the power grid rather than dissipating it as heat.

Compact Integration: Specifically designed for CNC cabinets where space is at a premium, featuring a high power-to-size ratio.

Wide Speed Range: Supports both low-speed high-torque cutting and high-speed finishing within a single spindle motor setup.

Reliability: Includes thermal protection for the motor and drive, overcurrent/overvoltage prevention, and ground fault protection.

Application Cases

The CIMR-M5D2018 is a standard component in high-end manufacturing environments:

CNC Machining Centers: The primary drive for main spindles in 3-axis and 5-axis milling machines.

Lathes & Turning Centers: Managing the heavy-duty start/stop cycles of turning spindles.

Grinding Machines: Ensuring constant surface speed regardless of the grinding wheel's diameter change.

High-Speed Woodworking: Precise control of routers and shapers requiring rapid acceleration.
