To change the frequency of frequency reference 2, for example, turn ON only the multi-
function input terminal where multi-step speed reference 2 is set, and turn OFF any
other multi-function input terminal.
For example, no settings for multi-step speed reference 3 or 4 will be required if only
frequency references 1 through 4 are used. Any multi-step speed reference not set is
regarded as turned-OFF input.

Setting the Inching Frequency Command (n032)
·
The inching frequency command must be set as multi-function input in order to use the
inching frequency command.

Note 1. The setting unit of the inching frequency command is changed with the set
value in n035 for frequency reference setting and decimal place selection. The
value will be set in 0.01-Hz increments if the frequency is less than 100 Hz and
0.1-Hz increments if the frequency is 100 Hz or over.
Note 2. In order to use the inching frequency command, one of the n050 through n056
parameters for multi-function digital input must be set to 10 as an inching fre-
quency command. Parameter n032 is selectable by turning ON the multi-func-
tion input set with the inching frequency command. The inching frequency com-
mand takes preference over the multi-step speed reference (i.e., when the
inching frequency command is ON, all multi-step speed reference input will be
ignored).
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 following cases.
S
Parameter n004 for frequency reference selection is set to 1, which enables fre-
quency reference 1, and the Inverter is in remote mode.
S
Parameter n008 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 16 are set with multi-step speed reference input.
·
The frequency reference can be changed, even during operation.
