● Motor
● Compressor
● Pressure sensor
● Motor temperature sensor (optional).
Open Loop Fan
This is a basic fan application where the fan is under the control of the Inverter.
The system comprises of the following components:
● Control Module
● Power Module
● Motor
● Fan
● Belt monitoring sensor (optional)
● Motor temperature sensor (optional)
Fixed Closed Loop Fan
The purpose of the closed-loop controlled fan application is to maintain a constant airflow
within a ventilation system, utilizing as little energy as possible.
A specific airflow and pressure for the fan system is set within the Inverter and these values
are directly monitored using the PID controller. Depending on a decrease or increase in
pressure readings, the Inverter will increase or decrease the speed of the fan accordingly.
The system comprises the following components:
● Control Module
● Power Module
● Motor
● Fan
● Feedback sensor
● Motor temperature sensor (optional).
Open Loop Pump
The purpose of this application is to maintain a constant level of fluid in a pumping system
and reacting to maintain the pre-determined level even if fluid is being drawn from the
system.
The analog input is used to set the frequency setpoint.
The system comprises the following components:
● Control Module
● Power Module
