The wireless communication card is especially useful for scenarios where you cannot directly
use the keypad to operate the VFD due to the restriction of the installation space. With a
mobile phone APP, you can operate the VFD in a maximum distance of 30 m. You can choose a
PCB antenna or an external sucker antenna. If the VFD is located in an open space and is a
molded case machine, you can use a built-in PCB antenna; and if it is a sheetmetal machine
and located in a metal cabinet, you need to use an external sucker antenna.
