1-Q-EC Amplifier Summary The basic function of EC motors electronics is sensors. A further distinction is made between 1-Q amplifier functions in motor operation. the electronic commutation of the motor winding. open or closed loop speed control. Direction reverse via digital signal. Simple speed controls are possible with Hall DEC Module 24/2 1-Q-EC Amplifier Operating modes Functionality Digital speed control or open loop speed con- Direction of rotation preset by a digital signal. trol operation can be preset by a digital signal.
