EC motors are equipped with a control module that allows for accurate
manual adjustment of motor speed. Motor speed range is from 300 to
1800rpm or maximum rpm for that model.
The control module features a 4 digit LED display that indicates %
demand of full speed and motor speed in rpm. The display also indicates
an error code message for minor diagnostics if required.
Motor speed can be changed by adjusting the speed control pot located
on the control module. A small screwdriver can be used to make the
speed adjustment.
