PWM3D-000 digital servo drive (MAX 480 Vac / 130 A) with IGBT bridge. Optimized for asynchronous motors with speed 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 standstill.
It is easy to commission thanks to a convenient LCD display with an easily navigable menu; Windows configuration software is available on request, with the possibility of viewing 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.
On this dedicated page you can check the list of asynchronous motors that have been tested with the PWM3D-000 servo drive on our test bench.
Versions
The PWM3D-000 digital servo-converter for asynchronous motors is designed to maximise system efficiency and is available in three versions, ideal for ensuring a flexible and rapid retrofit:
- PWM3D-000: can be powered by three-phase voltage or by DC voltage supplied by a regulated DC-BUS.
- PWM3D-010: can be powered exclusively by DC voltage supplied by a regulated DC-BUS.
- Power supply: in this version, the PWM3D is used exclusively to generate DC voltage to power other devices on the DC-BUS. Please contact our technical department for information on this version.
Further information
Output: maximum voltage: 480 Vac - maximum current depending on size: from 5 A to 130 A
Single-phase auxiliary supply: 230 Vac ±10% - 500 mA max (protect with external slow fuses 250 V - 1 A).
Power supply: from a minimum of 60 V to a maximum of 480 V three-phase, to be protected with fuses as indicated in the manual.
