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 refer-
ences 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 fre-
quency command.

(See note
1.) Default setting 6.0
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 input must be set to 10 as an inching frequency command. Parameter n032 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
ignored).
