Setting the Frequency Reference Chapter 5-5
No multi-step speed reference 3 settings will be required if only frequency
references 1 through 4 are used, for example. Any multi-step speed reference
not set is regarded as turned-OFF input.
Setting the Inching Frequency Command (n29)
The inching frequency command must be set as multi-function input in order
to use the inching frequency command.
Note 1. The value will be set in 0.1-Hz increments if the frequency is less than 100
Hz and 1-Hz increments if the frequency is 100 Hz or over.
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 ignored).
