7-Variable Speed Driver

Allows variable speed without guaranteeing stability over time;

During operation elements may vary:

• The resistant torque;

• The network voltage;

• The temperature;

And cause a change in the actual speed compared to the setpoint.

The speed variation is poorly adapted to low speeds.

• Maintains the actual speed in accordance with a very small deviation from the set speed despite disturbances;

• To do this, the controller must be constantly informed of the actual speed of the motor via a speed sensor..
