maxon ESCON2 servo controllers.
The brand new ESCON2 collection of maxon servo controllers with CANopen and I/O commanding achieves a brand new degree of smoothness, dynamics, and precision in machines and units due to an progressive methodology for Corridor sensor-based pace management and FOC commutation.
ESCON2 – One product line for a variety of functions
The ESCON2 platform gives pace and present/torque management mixed with extremely built-in, highly effective energy phases, making it the proper mixture for BLDC and DC motors in industrial, robotics, medical and analytical functions.
From the smallest “ESCON2 Nano 24/2” (23x16mm, 2.5g) to the highly effective “ESCON2 Compact 60/30” (as much as 60V / 30A), the ESCON2 product vary gives the proper resolution as a plug-in module for buyer electronics boards and, with its ready-to-connect “Compact” designs or in a housing, permits fast integration into machine and machine building.
The versatile command and monitoring of the ESCON2 permits each the usage of easy, preconfigured I/O capabilities and integration into CANopen techniques based mostly on CiA402 “Machine Profile for Drives and Movement Management”.
Excessive efficiency management and high-power density in a compact design
The ESCON2 is characterised by “most efficiency in minimal dimension,” which has been confirmed by suggestions from maxon clients:
“Regardless of their small dimension, the ESCON2 options are very highly effective and obtain the required motor currents, torques and speeds, even in steady operation with excessive vitality effectivity.”
10 kHz pace management fee, 50 kHz present management fee, field-oriented management (FOC), mixed with the most recent management algorithms and overload-resistant energy phases, allow motors to comply with excessive accelerations and exact movement profiles. For machines and tools, this implies quicker cycles and elevated throughput with prime quality and dimensional accuracy of the merchandise produced.
maxon gained an RBR50 Robotics Innovation Award from The Robotic Report for its new line of Excessive Effectivity Joints. You possibly can study extra concerning the RBR50 winners, together with the Robotic of the Yr, Startup of the Yr, Software of the Yr, and Robots for Good winners, by downloading this free report.
Excellent commutation and easy operation even with out an encoder
The sphere-oriented management generates sinusoidal motor currents over your complete pace vary as much as 120,000 rpm. Even for BLDC motors with Corridor sensors solely (with out encoders), a brand new maxon methodology (patent pending) permits way more exact pace measurement than was beforehand doable. As a consequence of their working precept, Corridor sensors solely present a low decision per rotor revolution and the switching edges are usually not completely distributed over one revolution of the motor shaft because of manufacturing tolerances.
The maxon methodology used for the primary time within the ESCON2 analyzes the switching edge distribution of the Corridor sensors throughout the first few motor revolutions and generates digital, exact sensor info from this. From a pace of just some hundred rpm, the pace stability and easy operation of the motor is corresponding to techniques based mostly on encoder suggestions.
Now accepting session submissions!
The pace management of the ESCON2 with Corridor sensor suggestions is considerably smoother and exhibits a decrease motor present oscillation than different servo controllers. The potential elimination of the encoder means value financial savings and a discount within the quantity of wiring required.
Open interfaces for commanding and information alternate
ESCON2 gives analog and digital inputs/outputs and bus interfaces equivalent to USB, serial interface / RS232 and CAN (CiA402) for configuration, exact commanding and entry to information for course of monitoring, IoT and predictive upkeep.
Primarily based on the CANopen machine profile CiA402, “PVM – Profile Velocity Mode,” “CSV – Cyclic Synchronous Velocity,” and “CST – Cyclic Synchronous Torque” modes are supported. As well as, two maxon-specific working modes can be found with “IOVM – I/O Velocity Mode” and “IOCM – I/O Present Mode” which mix management through analog and digital inputs/outputs with high-performance information alternate and course of suggestions through fieldbus. This ensures most flexibility, compatibility, and scalability to be used in easy units with analog management as much as absolutely digital techniques based mostly on CANopen.
As a system integrator put it: “The standardized CiA402 CANopen machine profile utilized by the ESCON2 reduces integration and improvement efforts and the chance of incompatibility when utilizing blended system parts.”
Updates and utility particular add-ons
Consumer suggestions and requests for practical enhancements are collected and prioritized by maxon. The ESCON2 performance is expanded freed from cost by means of common updates. For collection clients, maxon gives quick and environment friendly improvement of cost- and function-optimized particular person options.
“Movement Studio” makes it quick and simple
Profitable commissioning of recent drives is accomplished with just some entries and clicks utilizing “Startup” wizard and computerized “Regulation Tuning” of maxon’s “Movement Studio” software program. The created system configuration might be saved and transferred to different ESCON2 controllers.
