Yaskawa Electric Corporation CPCR-MR Servo Drive

The Yaskawa CPCR-MR Servopack is a DC servo drive module used in older Yaskawa/YASNAC CNC systems, notably Mori Seiki machines, functioning as a servo amplifier and speed controller for DC servomotors. It supports Yaskawa DC servomotors such as Minertia, Cup, and Hi-Cup types, provides precise control of motor speed, direction, and torque, and uses thyristor-based DC servo control, designed for panel- or machine-mounted axis control in CNC equipment. As a legacy, obsolete component commonly found as surplus or removed from machines, it is typically used in maintenance or replacement within existing legacy systems rather than new installations; typical replacements include the Yaskawa SGDR-SDA060A01B Servopack (Sigma II equivalent class), SGDM-20ADA Servo Drive (Sigma series upgrade), and SGDH-50DE Servopack.
