diagram on page 486.
This parameter is read-only.
Frequency reference after selection.
Displays the frequency reference after application of constant
frequencies, control panel reference, etc. See the control
chain diagram on page 486.
This parameter is read-only.
Frequency reference 7.
Displays the frequency reference after application of critical
frequencies, but before ramping and limiting. See the control
chain diagram on page 486.
This parameter is read-only.
Frequency reference before ramping and limiting.
