9.2 Selecting Frequency Command
9.2.1 Types of Frequency Command
 What types of frequency command input sources can be selected for the inverter and what is
their order of priority?
 The following diagram shows the parameters and input terminal functions that affect the output
frequency command input source selection.
 The command input source is set according to the "Frequency input source selection [A001]
*1
".
Please note that when multiple settings are turned on, the frequency command for each input
terminal function is selected with the following order or priority: "Multi-speed selection [CF1] to
[CF4]/[SF1] to [SF7] (02 to 05/32 to 38)", "Force terminal [F-TM] (51)", "Force operation [F-OP]
(31)" and then "Jogging [JG] (06)".
 When the command input source is the first/second motor multi-speed 0, multi-speed 1 to 15,
or jogging frequency, the "Output frequency setting or motor [F001]" parameter can be used to
change the frequency command. A setting change with the [F001] also changes the value of the
selected frequency input source parameter.
(For example, if the frequency input source is set to "Multi-speed 1 [A021]", the [A021] setting is
displayed in [F001]. If [F001] is changed, this is also reflected in [A021].)
 When the frequency input source is an analog input or Modbus communication, [F001] is used
to monitor the output frequency command value.
