<p>PURPOSE: A communication method between keypad and multiple inverters and system thereof are provided to communicate with a plurality of inverters with a keypad by using the original communication line. CONSTITUTION: A keypad is connected to an inverter(S81). MCU of a keypad has users select an inverter for communication(S82). MCU of an inverter input/output unit transmits data to SCI1(S84). The data are transmitted to the main unit of MCU of a directly connected inverter(S85). MCU of the main unit performs data handling such as motor driving by controlling a driving unit(S86).</p> |
