You can select the NPN/PNP mode and internal/external power through the U-type short connector.
NPN internal mode is adopted by default.

Note: As shown in Figure 4.19, the USB port can be used to upgrade the software, and the keypad
port can be used to connect an external keypad. The external keypad cannot be used when the
keypad of the VFD is used.
If input signal comes from NPN transistors, set the U-type short connector between +24V and PW
based on the power used according to the following figure.
