Setting the Frequency Reference
Chapter 5-5
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 frequency 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
corresponding parameter is changed simultaneously. For example, if
frequency reference 2 has been selected with multi-function input (a multi-
step speed reference), the set value in n22 (for frequency reference 2) will be
changed simultaneously when the frequency 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.
Setting the Key Sequential
Frequency (n08) • The Enter Key need not be pressed when changing the setting in n08. In
that case, the frequency reference will change when the set value is
changed with the Increment or Decrement Key while the data display is
continuously lit.
