9/5/2014 EMC_Brushless_and_Stepper_Motors Roger Enns 1 DC Motor PWM Speed Control • Previous methods of speed control used resistors to drop current/voltage in either the armature or the field. This results in a loss of electrical energy through the control resistor. • An electronic alt...
PURPOSE:To improve the reliability of a motor by calculating the deviation amount between a speed command signal and an actual rotating speed as a digital data, and varying the duty ratio of a pulse train on the basis of the calculated data, thereby eliminating the analog section. CONSTITUTION...

After changing the mode, test the operation to confirm that the lowest required motor speed is working as needed. If a lower spin threshold is required, try reducing the PWM frequency to the lowest possible value (usually about 25Hz) and work up towards the maximum of the motor controller....
