OTOR TYPES
The relationship between the voltage supplied to a motor and its operating
speed is described by a motor curve. This curve varies with the make and
capacity of the motor. The various motors available in the industry have been
divided into ten categories and the controller has been programmed with a
different motor curve for each of these categories. To ensure that the
controller supplies the correct voltages, an appropriate curve must be
selected for Stage 1 and Stage 2 according to the type of fan motors used.
