HD3L - Open-loop Controller

Product Features

3 phase



Asynchronous motor integration

Support the controls of synchronous and asynchronous motor, and have good commonality.


With the leading vector control technology

Have the leading traction machine vector control technology and superior control performance.

Smooth S-curve of acceleration and deceleration

The optimized S-curve of acceleration and deceleration can make passengers have a good sense of comfort.

Four-quadrant operation

All are built-in the dynamic braking unit.

Can configure the power regenerative unit to achieve four-quadrant operation and energy saving.

Flexible start and stop time-sequence logic

It can match different elevator control and PLC.

Motor parameter static auto-tuning technology

When commissioning, no need for the car, you still can implement the parameter static auto-tuning for the asynchronous motor.

Start torque auto-compensation for no weighing device

No need for the weighing device, you can achieve the elevator start without impact.

Have good consistent, strong environmental adaptability, and more convenient for customer commission-ing, repair and maintenance.
