The VFD has been equipped with the LCD keypad as a standard configuration part. You can use the keypad to control the start and stop, read status data, and set parameters of the VFD.
Note:
l The LCD keypad is equipped with a real-time clock, which can run properly after being installed with batteries even if the power line is disconnected. The clock battery (type: CR2032) is user purchased.
l The LCD keypad has the parameter copying function.
l If you need install the keypad on another position rather than on the VFD, use M3 screws or a keypad installation bracket for fixing, and use a keypad extension cable with a standard RJ45 crystal head.
