The inverter run/stop can be controlled with just the reference frequency signal. By setting the run frequency
IF ,- ,_, ,-, I and the run frequency hysteresis IF 1-1 '::15 I . the inverter will start running when the reference
frequency
signal is higher than point B in the following diagram, and will stop when less than point A.
* For example, when using the inverter for HVAC applications, etc., and automatically operating from a
room temperature signal, the inverter can be stopped when the reference frequency
signal drops below
30Hz.
