maxon ESCON2 servo controllers.
The brand new ESCON2 sequence of maxon servo controllers with CANopen and I/O commanding achieves a brand new stage of smoothness, dynamics, and precision in machines and units because of an revolutionary methodology for Corridor sensor-based velocity management and FOC commutation.
ESCON2 – One product line for a variety of functions
The ESCON2 platform affords velocity and present/torque management mixed with extremely built-in, highly effective energy levels, 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 affords the precise resolution as a plug-in module for buyer electronics boards and, with its ready-to-connect “Compact” designs or in a housing, allows fast integration into gadget and machine building.
The versatile command and monitoring of the ESCON2 permits each using easy, preconfigured I/O features and integration into CANopen programs based mostly on CiA402 “Gadget 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 measurement,” which has been confirmed by suggestions from maxon prospects:
“Regardless of their small measurement, the ESCON2 options are very highly effective and obtain the required motor currents, torques and speeds, even in steady operation with excessive power effectivity.”
10 kHz velocity management fee, 50 kHz present management fee, field-oriented management (FOC), mixed with the newest management algorithms and overload-resistant energy levels, allow motors to observe excessive accelerations and exact movement profiles. For machines and gear, this implies sooner cycles and elevated throughput with prime quality and dimensional accuracy of the merchandise produced.
maxon received an RBR50 Robotics Innovation Award from The Robotic Report for its new line of Excessive Effectivity Joints. You’ll be able to be taught extra in regards to the RBR50 winners, together with the Robotic of the Yr, Startup of the Yr, Utility of the Yr, and Robots for Good winners, by downloading this free report.
Good commutation and clean operation even with out an encoder
The sector-oriented management generates sinusoidal motor currents over your complete velocity 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 far more exact velocity measurement than was beforehand doable. On account 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 attributable to manufacturing tolerances.
The maxon methodology used for the primary time within the ESCON2 analyzes the switching edge distribution of the Corridor sensors in the course of the first few motor revolutions and generates digital, exact sensor data from this. From a velocity of just some hundred rpm, the velocity stability and clean operation of the motor is similar to programs based mostly on encoder suggestions.
The velocity management of the ESCON2 with Corridor sensor suggestions is considerably smoother and reveals 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 knowledge change
ESCON2 affords analog and digital inputs/outputs and bus interfaces akin to USB, serial interface / RS232 and CAN (CiA402) for configuration, exact commanding and entry to knowledge for course of monitoring, IoT and predictive upkeep.
Primarily based on the CANopen gadget 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 knowledge change 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 totally digital programs based mostly on CANopen.
As a system integrator put it: “The standardized CiA402 CANopen gadget profile utilized by the ESCON2 reduces integration and improvement efforts and the danger of incompatibility when utilizing combined system elements.”
Updates and utility particular add-ons
Person suggestions and requests for useful enhancements are collected and prioritized by maxon. The ESCON2 performance is expanded freed from cost by means of common updates. For sequence prospects, maxon affords 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 could be saved and transferred to different ESCON2 controllers.
