Function Applications

The range of frequency reference values written through communication by using the 1000H address is
–10000 to 10000 (decimal), corresponding to the frequency range of –100.00% to +100.00%. (–100.00%
corresponds to the negative maximum frequency, and +100.00% corresponds to the maximum
frequency.) Assume that F0-10 (maximum frequency) is set to 50 Hz. If the frequency reference in the
write command is 2710H, which is equivalent to 10000 in decimal, the actual written frequency
reference is 50 Hz (50 x 100%).
4.1.2.9 Selecting Source of Auxiliary Frequency Reference
There are nine auxiliary frequency reference sources available, including digital setting (non-retentive
at power failure), digital setting (retentive at power failure), AI1, AI2, AI3, multi-reference, simple PLC,
PID, and communication, which can be selected by setting F0-04 (0 to 9).
When used as an independent frequency reference source, the auxiliary frequency reference source is
used in the same way as the main frequency reference source. The following figure shows the block
diagram. The auxiliary frequency reference source can also be used for superposition of the main and
auxiliary frequency references. For details, see the "Selecting Source of Main Frequency and Auxiliary
Frequency Superposition Reference" section.
