Description

1. Basic Product Info

Manufacturer: Yaskawa Electric Japan
Series: VARISPEED VS‑656MRX compact regenerative power supply unit for CNC spindle shared DC bus
Model Code: CIMR‑MRXN2015|200V three-phase input grade, rated matching 15kW spindle drive load
  • MRX: Compact optimized version of standard MR5 regenerative series;

  • N: Equipped with built-in internal DC24V auxiliary control power supply for CNC peripheral control circuit;

  • 20 = 200V AC input class; 15 = nominal 15kW rated supporting capacity

    Application: CNC lathe, machining center shared DC bus system, supply DC power for multiple CIMR‑M5N spindle inverters; four-quadrant energy regeneration back to grid to cancel brake resistor

    Product Status: Discontinued original production; only new surplus stock & refurbished replacement available for old machine maintenance

2. Electrical Ratings

3‑Phase AC Input Side

  • Continuous rated DC output power:15kW

  • Continuous DC output current:58A; 30min overload DC output current:78A

  • Embedded auxiliary: Integrated DC24V control power output for external CNC control power feed

3. Mechanical & Environmental Data

  • Net weight:10.5kg

  • Cooling mode: Built-in axial fan forced air cooling

  • Operation ambient temperature:0℃~+40℃; storage temperature:-20℃~+60℃

  • Installation: Indoor cabinet wall-mounted; non-condensing, free of corrosive gas and conductive dust, ambient humidity 5~95%RH non-dewing

4. Core Functions

  1. Full grid regeneration: Spindle braking regenerated power fed back directly to AC mains, eliminate external braking resistance, reduce cabinet heat generation

  2. Multi-drive parallel DC bus: Single MRXN2015 can supply several parallel M5N spindle inverters on same CNC equipment

  3. Standard matching: Paired with CIMR‑M5N2015 15kW spindle inverter for full vector spindle control, support spindle orientation for auto tool change

  4. Complete protection: Overcurrent, overvoltage, undervoltage, input phase loss, heatsink overheat, electronic overload protection with fault relay contact alarm output for CNC linkage stop

5. Replacement Option

Upgrade alternative: Yaskawa D1000 series 200V grade 18.5kW regenerative power unit as direct functional substitute.
