CIMR-MR5A4045 Yaskawa

 

70 KVA, Serial VS626-MR5

The VS-626MR5 is a highly reliable AC vector controlled inverter drive designed for controlling high speed, compact AC motors used in machine tool spindle drive applications. Vector controlled technology through the use of a digital signal processor and proprietary algorithms for speed, torque, and current control allows for minimum speed and torque variations during cutting. This impacts accuracy and surface finish of precision parts. 100% back-to-line power regeneration provides quick spindle deceleration times not limited by the ohmic value of externally mounted regeneration resistors. This allows for faster tool changes and increased machine productivity.
