Yaskawa Electric CPCR-MR 052N Servopack DF6101208 Servo Board CPCRMR

Description:

The Yaskawa CPCR-MR 052N is a DC servo Servopack drive module and control board assembly used in Yaskawa/YASNAC CNC systems, including Mori Seiki machines. It functions as a servo amplifier and control board (DF6101208 revision) that regulates motor speed, torque, and positioning for DC servomotors. The CPCR-MR series is designed for high-precision motion control, supporting rapid start/stop, reversing, and accurate positioning in industrial machinery. This specific unit is typically a servo board assembly (DF6101208 Rev. B/C) removed from a larger Servopack and is commonly found in used or surplus condition.

Applications:

The Yaskawa CPCR-MR Servopack board/module is used in CNC machinery such as lathes and machining centers (e.g., Mori Seiki) for axis motion control. It is applied in manufacturing environments requiring precise servo positioning and speed control. Today, it is mainly used for maintenance, repair, or replacement in legacy CNC systems rather than new installations.
