Can circulating pump inverter increase the operating buttons

Can be increased, usually add an emergency stop button. Add an emergency stop button outside the inverter, introduce the button signal into the DI terminal of the inverter, and then define this DI terminal as an emergency stop terminal inside the inverter. Connect a tight stop button outside, with a normally closed contact, connect any input point of the frequency converter, programmed internally, i.e., power normal, power loss stop, so as to prevent the tight stop button is often not used, and lose the usefulness of doing so, with a normally closed contact with a monitoring role. Once this button is tapped, the inverter immediately performs an emergency stop motor.
