Inverter Drives SMVector Application Example: Temperature Controlling Pump (Cooling)

The inverter will automatically control the speed of the pump motor to maintain the desired temperature in 
the system. The user can set a desired temperature with the keypad (or potentiometer, or preset inputs). The
inverter will compare the setpoint to the actual analog feedback signal coming from the temperature sensor and
automatically adjust motor speed to achieve the setpoint temperature.

The inverter reaction to the analog feedback and the actual speed output value can be influenced greatly by the
PID settings in the inverter

• The user must input the type of signal that will represent the setpoint (keypad, analog, preset)
• The user must input the type of signal that will represent the feedback (analog)
• The user must tune the P, I, and D gains for the actual system
