Electrical connection
nThe mains connection and the contacting of all control and signal inputs are carried out directly on the motor. This eliminates the time-consuming connection with shielded cables.

Speed control
nThe infinitely variable speed input of the motor is done by connecting an external potentiometer (accessory) or an external 0-10 V/PWM signal.
