Yaskawa CIMR-MT2-5.5K

Yaskawa CIMR-MT2-5.5K belongs to the vintage VS-626MT II spindle drive series, 5.5kW, 200V class spindle inverter dedicated for CNC machine tool spindle motors. It is an obsolete Yaskawa spindle drive unit, widely matched with YASNAC CNC systems to realize high-speed spindle speed regulation and constant torque cutting control. This model has been discontinued and is mainly supplied as maintenance spare parts for old machining centers and lathes. The spindle drive inverter outputs adjustable AC power to drive machine spindle motors, the spindle drive inverter delivers stable high low-speed torque for metal cutting. CNC maintenance engineers rely on the spindle drive inverter for old vertical machining centers, CNC lathes and milling equipment spindle renovation. The spindle drive inverter supports analog speed command and encoder feedback closed-loop speed control.

Yaskawa CIMR-MT2-5.5K adopts dedicated spindle control algorithm, featuring wide speed adjustment range and strong overload capacity for milling, boring and turning processes. It integrates multiple protection functions including overcurrent, overvoltage, undervoltage, overheat and motor overload protection. The spindle speed regulation realizes stepless speed change for workpiece roughing and finishing. Reliable spindle speed regulation maintains stable cutting speed to guarantee workpiece machining precision. Technicians complete motor auto-tuning and parameter setting to optimize spindle speed regulation. Encoder feedback interface ensures high accuracy closed-loop spindle speed regulation under variable cutting loads.

Yaskawa CIMR-MT2-5.5K is widely used for legacy machining centers, old CNC milling machines and metal processing production equipment. Every drive undergoes power loading test, signal port inspection and aging test before shipment. The CNC spindle drive assembly consists of spindle inverter, spindle motor and encoder to build complete spindle motion control system. This spindle drive provides dependable CNC spindle drive assembly performance for long-cycle metal cutting production. Standard control terminals and abundant fault diagnosis codes preserve stable CNC spindle drive assembly performance over long service cycles. CNC retrofit customers select this unit for spare part replacement and maintenance of existing CNC spindle drive assembly.
