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).
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 following cases.
Parameter n03 for frequency reference selection is set to 1, which enables frequen-
cy reference 1, and the Inverter is in remote mode.
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.
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 corre-
sponding parameter is changed simultaneously. For example, if frequency reference 2
has been selected with multi-function input (a multi-step speed reference), the set val-
ue in n22 (for frequency reference 2) will be changed simultaneously when the fre-
quency reference is changed while the FREF indicator is lit.
Take the following default steps, for example, to change the frequency reference with
the FREF indicator 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.
