EC: Escon module 24/2

Motion Control - Drives, servo drives: The Escon module 24/2 is a small-sized, powerful 4-quadrant PWM-based OEM servo controller for the highly efficient control of permanent magnet-activated brushed dc motors and brushless dc motors up to approximately 48 Watts. This is a Control Engineering 2016 Engineers’ Choice finalist.

The Escon Module 24/2 is designed to command permanent-magnet activated brushed dc motors and BLDC motors (brushless dc motors, so-called EC motors) with Hall sensors up to 48 Watts continuous output and 144-Watt peak output.

It features excellent controller characteristics. The drift-free yet extremely dynamic speed behavior enables speeds up to 150,000 rpm. The innovative module provides extensive functionality with free configurable digital and analog inputs/outputs. It perfectly matches maxon’s motor range to suit even highest-demand applications and dynamic drive solutions. The module can be operated in speed controller (closed loop), speed controller (open loop), and current controller. All these features create ideal conditions for the use in high-demand applications involving miniature servo controllers.

The powerful OEM plug-in module easily integrates into complex applications with little effort. A distinctive benefit: customers can fully focus on their main task; the development of their own device. For the motor control part they can make use of maxon motor’s vast drive know-how already built into the Escon module. A detailed Motherboard Design Guide is available for integration to OEM PCBs and a suitable motherboard makes initial commissioning a simple task.

The compact servo controller is controlled by an analog set value. It can be specified by means of analog voltage, by external potentiometer, by defined value, by means of PWM signal, or with RC servo signal with variable duty cycle. Other interesting features are for instance the ability to enable or disable the power stage depending on the direction of rotation as well as acceleration and deceleration by employment of defined speed ramps. The speed can be controlled by means of digital incremental encoder (two channels, with/without line driver), dc tacho, or Hall sensors.
