EnDAT Encoder transducer
The PWM3D-000 digital servo drive is ideal for driving induction servomotors of any brand, equipped with a speed transducer, with voltages up to 480 V and maximum currents up to 130 A. Fully digital, with an IGBT bridge and 4-quadrant operation with no deadband at zero speed: the motor shaft is rigidly held even at...Continue reading
Transducer converters designed by Alter Elettronica are the essential link for those undertaking the refurbishment of industrial plants and machine tools. Very often the installed motor is in perfect working order, but uses an obsolete speed or position transducer — analogue or based on closed proprietary protocols — making communication with modern standard drives impossible....
"The PWM3D-001 digital servo drive is ideal for driving synchronous servomotors (permanent magnet brushless, with sinusoidal or trapezoidal commutation) and DC motors of any brand, equipped with a speed transducer, with voltages up to 480 V and maximum currents up to 118 A (rms). Fully digital, with an IGBT bridge and 4-quadrant operation with no...Continue reading
Designed specifically for reading optical scales and direct position transducers, the 13/014 converter interfaces seamlessly with EnDat Linear transducers. In retrofits of large milling machines, lathes or boring machines, the linear optical scale is the heart of dimensional accuracy. This module allows any commercial Numerical Control (CNC) system or servo drive equipped with a TTL...Continue reading
The 13/012 converter is Alter Elettronica’s technical solution for interfacing rotary absolute encoders operating with the EnDat 2.1 and 2.2 protocol (a standard typically found in Heidenhain systems) with standard commercial servo drives. On machine tools and in machining centres, EnDat is the benchmark standard for precision. However, it often restricts the choice of replacement...
How can we drive an electric motor equipped with a Fanuc Pulsecoder? Let’s go back in time For decades the d.c. tacho-generator was used as a speed transducer for electric motors; all the control equipment had an input for this type of transducer and there were no compatibility problems. Then the resolvers and TTL encoders...Continue reading
