Precautions for Correct Use
• In the above example, [AA101]=08(RS 485) is enabled. For details, see the following expla-
nation.
• Other command destinations can be chosen even when RS485 (Modbus communication,
EzCOM function) and program function (Drive Programming) are being used.
• If an operation command is given from the operation screen of PC software CX-Drive,
[AA101]=07 and [AA111]=03 are forcedly overwritten when the operation screen opens. Set
[AA101]=07 and [AA111]=03.
The LCD operator is used to give a frequency command.
For operation using the LCD operator, the operation direction can be changed by setting RUN-key
Direction of LCD operator, 1st-motor [AA-12].
Precautions for Correct Use
• The output of the inverter (operation of the motor) requires not only a frequency command
but also an operation command.
• The main and auxiliary speeds can be selected and calculated by using the input terminal
function [SCHG] and the operator selection. For details, see 6-4-8 Case where Command Is
Given with Main Speed Command and Auxiliary Speed Command on page 6-35.
• If not using the LCD operator, you need to make FW/RV direction switching from each com-
mand.
