The PWM3D-001 digital servo drive is ideal for driving synchronous servomotors (permanent magnet brushless) and direct current of any brand, equipped with a speed transducer, with voltages up to 480V and maximum currents up to 200Arms, sinusoidal or trapezoidal.
Fully digital with IGBT bridge, operation in 4 quadrants, with no zero play.
The PWM3D-001 digital servo drive is easy to install thanks to a convenient LCD display with easily navigable menu; a software to be used on PC is available on request, with the possibility to display the parameters in graphic form (oscilloscope).
The "AutoTune" function allows the customer to speed up commissioning and better adapt the servo drive to the motor.
Versions
This servo drive is available in two versions:
- PWM3D-001: it can be powered with three-phase voltage or with direct voltage supplied by a regulated DC-BUS.
- PWM3D-011: 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.
