Description
Servo Amplifier Card RZ877A for Mitsubishi CR2B Controller
The Servo Amplifier RZ877A is available from ROBTEC as an original spare part, ex stock.
The RZ877A is a servo amplifier card for the Mitsubishi CR2B controller. It converts the digital control signals of the servo CPU into powerful drive currents for the servo motors of the robot. The RZ877A supplies several axes simultaneously and integrates protective functions such as overcurrent detection, overtemperature shutdown and brake control. A defect in this card typically manifests itself through axis errors, vibration or 9000-series alarms.

Availability
This controller generation is no longer produced. Original spare parts are hardly available anywhere in the world. Servo amplifiers are subject to particularly high wear due to the permanent power load. Available tested cards are correspondingly rare.
Service and retrofit
Alongside spare parts, ROBTEC also offers retrofit and modernization services. In the case of recurring servo amplifier defects, we also check the condition of the motors and brakes in order to avoid consequential damage.
