Note The frequency reference gain and frequency reference bias can be set with
the GAIN indicator
and BIAS indicator.
H Frequency Reference Selection (n024 to n029) through Digital
Operator
S Frequency
references can be input through the Digital Operator by setting the unit of the
frequency
references
with n024 and the values of the frequency references with
n025 to n028. The inching
frequency reference must be set with n029 if an inching frequency is required.

Determine the display method of the maximum frequency set with n012. A frequency less
than the maximum frequency will be displayed proportionally.
Example: Set n024 to 1100 so that “10.0” will be displayed at the maximum frequency.
10.0 →1100
