MITSUBISHI MDS-DH-SP-480 CNC Spindle drive unit 400V 480A

Buy online your MITSUBISHI MDS-DH-SP-480 CNC Spindle drive unit 400V 480A reference MDS-DH-SP-480 from our US e-store Cnc-shopping USA, specialist in CNC machine-tools spare parts.

The unit is a MITSUBISHI Electric spindle inverter from the MDS-DH family for controlling MITSUBISHI AC spindle motors on 400 V class CNC machine tools. It is commonly selected as a replacement unit or stocked spare part for maintenance programs, retrofit tasks and emergency repairs where reliable spindle control is required.

Operating on a shared DC link between 513 and 648 V DC from the matching MDS power supply, this module provides a three phase output around 340 V AC to the spindle motor. It supports 132 A continuous output with up to 55 kW motor power when correctly paired. A 480 A peak current capability covers acceleration and high torque events typical on machining centers and heavy turning operations.

In MDS-D and MDS-DH cabinets, the spindle module is installed next to the power supply to maintain a short and reliable DC bus connection. Each drive generates heat during continuous duty, so leave top and bottom clearance for airflow as referenced in Mitsubishi connection guidelines to maintain thermal stability during extended production.

Drive selection follows the installed motor characteristics. Choose the MDS-DH-SP-480 when the spindle requires the 132 A class within the 400 V range and up to 55 kW output. The module integrates within Mitsubishi CNC platforms built around the MDS-D and MDS-DH system, widely used on Japanese and international machine tools.

This model is frequently used to replace failed inverters that trigger overcurrent faults, thermal trips or cannot sustain acceleration under load. Keeping a stocked spare shortens downtime on critical machines and supports planned maintenance windows. For like for like changeouts, match the exact code including variants such as MDSDHSP480 for cabinet fit, terminals and harness reach.

Service teams apply this unit during rebuilds and retrofits when the existing Mitsubishi spindle motor and MDS platform are retained. Aligning the drive rating with the motor’s current and voltage class helps stabilize spindle behavior, reduce nuisance alarms and restore machine uptime on the production floor.

Units from Cnc-shopping USA can be supplied as tested modules, verified on CNC simulators with spindle motors by skilled engineers for power stage performance and control functionality. Professional packing is used for industrial shipments, and a warranty is provided according to our terms. Many stocked items ship directly from our Florida facility, with dispatch timing dependent on availability.

This item can serve as an emergency spare for older Mitsubishi CNC installations to reduce unexpected downtime. Cnc-shopping USA supports sourcing of hard to find or obsolete parts and can assist with repair service, exchange service or a refurbished unit when appropriate.

Frequently asked questions about MDS-DH-SP-480:

Is it a direct replacement for units labeled MDSDHSP480 or MDS-DH-SP-480?
Yes. Match the nameplate code to confirm a drop-in replacement without cabinet changes.

What supply is required for the module?
It connects to the MDS common DC link, typically 513 to 648 V DC, provided by the compatible Mitsubishi power supply module in the same rack.

What spindle motor power does it support?
When correctly paired, it supports up to about 55 kW with 132 A continuous output and short term peaks up to 480 A for acceleration.

Will the machine parameters need to be transferred?
Spindle parameters must match your machine configuration. Maintenance teams usually back up and restore settings from the original system during replacement to ensure proper operation.
