maxon motor introduces the ESCON Module 24/2 OEM plug-in module. This high-performance four-quadrant PWM servomotor controller is designed to command permanent-magnet-activated brushed and brushless DC motors with Hall sensors up to 48 W continuous output and 144 W peak output. Its features include high usability, exceptional performance and power density in servomotor controller technology.

Also, the entire maxon ESCON servo controller line now offers new functionality. An RC servo signal evaluation for speed or current set values, current limiter, and offset or the option to predefine analog speed ramps are all included.

The innovative OEM plug-in module features excellent controller characteristics. The drift-free yet extremely dynamic speed behavior enables speeds up to 150,000 rpm. It provides extensive functionality with free configurable digital and analog inputs/outputs and can operate in various modes, such as open and closed loop speed controllers and current controller. A match for maxon’s motor range, the miniaturized ESCON Module 24/2 suits even the highest demanding applications and most dynamic drive solutions. It integrates into complex applications with little effort.

A detailed Motherboard Design Guide is available for integration to OEM PCBs, and a suitable motherboard makes initial commissioning a simple task. This allows the OEM to focus on the development of their device and simply rely on maxon for the motor control part that is provided in the ESCON module.

The compact servo controller is controlled by an analog set value. It can be specified using analog voltage, by external potentiometer, by defined value, using PWM signal or with RC servo signal with variable duty cycle. Other key features include the ability to enable or disable the power stage depending on the direction of rotation as well as acceleration and deceleration by the employment of defined speed ramps. Speed control is done using digital incremental encoder, DC tachometer or Hall sensors. This requires no in-depth knowledge of drive technology for operation.

When connected to a PC via a USB port, it can easily and efficiently be parameterized with the graphical ESCON Studio user interface. A variety of functions and user-friendly wizards as well as a well-designed automated fine-tuning controller procedure assist during commissioning, for configuration of inputs and outputs, and diagnostics.

The ESCON Module 24/2 features protective circuitry against overcurrent, excess temperature, undervoltage and overvoltage, voltage transients and short-circuits in the motor cable. It also is equipped with protected digital inputs and outputs and adjustable current limitation to protect motor and load. Motor current and actual motor shaft speed are monitored using analog output voltage.

The wide range of both input voltage and operating temperature of 60° C (140°F) and a surplus derating allow flexible use in almost all drive solutions. These include small electronic appliances and equipment engineering or robotics. With its exceptional efficiency of 92% and miniature dimensions, the ESCON Module 24/2 is a choice for mobile, highly efficient yet consumption-optimized applications.
