MC Series Servo Motor Driver Manual
VersionV2.1
The MC series driver is a new generation of high-performance brushless servo driver launched by MyActuator, which can be widely used to drive various BLDC/PMSM motors. This series is MyActuator Intelligent based on years of low-voltage DC servo market experience and combined Various types of customer demand feedback. The drive includes various features, such as: power-off memory to realize data recording under power-off conditions; bus current sampling: real-time knowledge of the current-torque relationship and precise control of the torque output. At the same time, we match the friendly visual graphical interface for the new driver, which is convenient for users to quickly familiar with the product features. For more product information and user experience, please contact your dedicated technical consultant.
