Technical FAQs 4

How do you connect a potentiometer to an inverter?

Connect one end of the potentiometer (end 1) to the +10V (or +5V) power output of the inverter. Connect the other end of the potentiometer (end #3) to the GND (ground) terminal of the inverter. Connect the middle end (end #2) of the potentiometer to the analog input (AI) terminal of the inverter.

How can a potentiometer adjust the output frequency range of the inverter?

The input value of the external potentiometer can adjust the output frequency range of the inverter by setting the magnification. The specific magnification setting method needs to be debug ged and experimented in combination with the specific application situation.

How do you protect a potentiometer from electromagnetic interference?

Avoid signal interference: Use shielded wire to connect the potentiometer to reduce external electromagnetic interference. Take safety precautions: When adjusting the inverter and motor, make sure to operate with power off to prevent accidental electric shock.

How to connect a potentiometer to a VFD?

Confirm that the VFD supports analog input: The VFD usually has an analog input port (e.g., AI, VR, or 0-10V, 4-20mA interface), make sure that the VFD supports potentiometer speed control. 2. Connect the potentiometer to the inverter
