Yaskawa Electric CPCR-MR Servopack Drive Board Assembyl Drive Module Mori Seik CPCRMR

Description:

The Yaskawa CPCR-MR Servopack is a DC servo drive module used in older Yaskawa/YASNAC CNC systems, particularly in Mori Seiki machines. It functions as a servo amplifier and speed controller for DC servomotors, providing precise control of motor speed, direction, and torque. The CPCR-MR series is designed to work with various Yaskawa servomotor types such as Minertia, Cup, and Hi-Cup motors, delivering stable motion control across a wide operating range. This unit is typically a drive board assembly or module removed from CNC equipment and is considered a legacy component.

Applications:

The Yaskawa CPCR-MR Servopack module is commonly used in CNC machinery such as lathes and machining centers (e.g., Mori Seiki systems) for axis control and motion positioning. It is found in industrial manufacturing environments where precise servo motor control is required for machining operations. Today, these units are primarily used for maintenance, repair, or replacement in existing legacy CNC systems rather than new installations.
