Setting the Frequency Reference Chapter 5-5
5-5-4 Setting Frequency References through Key Sequences
The following description provides information on parameters related to
frequency reference settings through key sequences on the Digital Operator
Setting Frequency References 1 through 8 and the Inching Frequency
Command (n21 through n28 and n29)
A total of nine frequency references (frequency references 1 through 8) and
an inching frequency command can be set together in the Inverter.
Setting Frequency References 1 through 8 (n21 through n28)
Note 1. Values 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. Frequency reference 1 is enabled with n03 for frequency reference
selection set to 1.
3. Frequency references 2 through 8 are enabled by setting multi-step speed
references 1, 2, and 3 in n36 through n39 for multi-function input. Refer to
the following table for the relationship between multi-step speed references
1 through 3 and frequency references 1 through 8.
