The PWM3D-000 digital servo drive is ideal for driving induction servomotors of any brand, equipped with a speed transducer, with voltages up to 480V and maximum currents up to 200A.
Fully digital with IGBT bridge, in the 4 quadrants, without zero play.
LCD display with easily navigable menu; a PC software is available on request with the possibility to view the parameters in graphical form (oscilloscope).
The "AutoTune" function allows the customer to speed up commissioning and better adapt the servo drive to the motor.
In this specific page (link) it is possible to check the list of some asynchronous motors that have been operated with the PWM3D-000 servo drive connected to our test bench.
Versions
This servo drive is available in two versions:
- PWM3D-000: it can be powered with three-phase voltage or with direct voltage supplied by a regulated DC-BUS.
- PWM3D-010: it can be powered only with DC voltage supplied by a regulated DC-BUS.
When it is powered by DC-BUS, it is possible to recover the braking current in line by connecting it to the power supply ALTER PSR3.
Further information
Maximum output voltage: 480 Vac
Maximum output current: from 6A to 200A
