Chapter 12 Inverter Functions
12.4 Select a frequency command.
12.4.1 Type of frequency command
• The frequency command selected in each function
is enabled.
• For details, see the next and subsequent sections.
• The value of the enabled frequency command is
shown in [FA-01]. If the frequency command can be
modified on the operator keypad, the modification is
made by changing [FA-01] when, for example,
[AA101]=07 is effective. ([Ab110] is overwritten
when [FA-01] is changed.)
• In the above example, [AA101]=07 (operator
keypad) is enabled. For details, see the following
explanation.
• Other command destinations can be chosen even
when RS485 (Modbus communication, EzCOM
function) and program function (EzSQ) are being
used.
• The operation of the inverter requires not only a
frequency command but also an operation
command.
• To use the second setting switching [SET] of the
input terminal function, replace 1 of the third digit of
the parameter with 2. Ex.: [AA101]->[AA201]. If the
third digit is “-”, the parameter is shared for the first
and second settings.
• If an operation command is given from the
operation screen of PC software ProDriveNext,
[AA101]=07 and [AA111]=03 are forcedly
overwritten when the operation screen opens.
When the operation screen closes, the values
returned to the ones used before the screen
opened.
• Functions not assigned to the input terminal
functions [CA-01]-[CA-11] become OFF.
