Compact 4-axis controller serves highly dynamic applications

Automation / Robotics Electronics controller EtherCAT

NANOTEC  CM-CPB3-44 EtherCAT controller controls four brushless dc or stepper motors with a rated power of up to 150 watts per axis. Feedback on the motor position is provided by Hall sensors or incremental or SSI encoders. Each axis is equipped with four digital inputs, two outputs, one analog input and one output for a safety brake. Field-oriented torque, speed and position control, combined with other features such as acceleration feedforward and jerk-limited ramps, ensures optimum dynamic performance and cycle time. The compact 4-axis controller comes in a version with 3 A peak current for small stepper motors and in a version with 9A peak current for BLDC motors and larger stepper motors.
