Basic Operation
Note 2. In order to use the inching frequency command, one of the n36 through n39 parameters for
multi-function input must be set to 10 as an inching frequency command. Parameter n29 is
selectable by turning on the multi-function input set with the inching frequency command. The
inching frequency command takes precedence over the multi-step speed reference (i.e.,
when the inching frequency command is ON, all multi-step speed reference input will be ig-
nored).
H Setting the Frequency Reference with the FREF Indicator Lit
• The frequency reference can be set while the FREF indicator of the Digital Operator is lit in the follow-
ing cases.
S Parameter n03 for frequency reference selection is set to 1, which enables frequency reference 1,
and the Inverter is in remote mode.
S Parameter n07 for frequency selection in local mode is set to 1, which enables key sequences on
the Digital Operator, and the Inverter is in local mode.
S Frequency references 2 through 8 are set with multi-step speed reference input.
• The frequency reference can be changed, even during operation.
• When the frequency reference is changed while the FREF indicator is lit, the corresponding parameter
is changed simultaneously. For example, if frequency reference 2 has been selected with multi-func-
tion input (a multi-step speed reference), the set value in n22 (for frequency reference 2) will be
changed simultaneously when the frequency reference is changed while the FREF indicator is lit.
• Take the following default steps, for example, to change the frequency reference with the FREF indi-
cator lit.

D Setting the Key Sequential Frequency (n08)
• The Enter Key need not be pressed when changing the setting in n08. In that case, the frequency
reference will change when the set value is changed with the Increment or Decrement Key while the
data display is continuously lit.

Note If the FREF indicator has not been lit, press the Mode Key
repeatedly until the FREF indicator is lit.
Use the Increment or Decrement Key to set the frequency
reference.
The data display will flash while the frequency reference is set.
Press the Enter Key so that the set value will be entered and
the data display will be lit.
