Servo Motor Controller

The new maxon motor ESCON 70/10 servo controller possesses easy usability and peak control properties. The high power density 4-quadrant pulse width modulated (PWM) servo motor controller gives efficient control of permanent-magnet brushed DC motors (PMDC) and brushless DC motors (BLDC motors) using Hall sensors with a power rating to ~700 W. It has fast digital current control with a huge bandwidth for precise motor torque and current control. The speed behaviour is fluctuation-free and extremely dynamic with a motor speed range from 0 to 150,000 rpm. It has a broad range of functionality with completely configurable analogue and digital outputs and in-puts. It can be used in numerous motion control operating conditions from current controller to speed controller in both open and closed loop. It is controlled with an analogue set value input that can be given from either an external source or using an internal potentiometer. Alternatively, the motor can be controlled via PWM input signal. It features direction oriented enabling if desired and the user can define the feedback mode using an encoder, tacho or Hall sensors. When connected to a PC via a USB port, the servo motor controller can easily be configured with the graphical user interface "ESCON Studio". A large variety of functions, software wizards, and a well-designed automatic procedure to fine-tune the controller come in handy during startup and configuration.
