5-5 Frequency Reference Settings
5-5-1 Frequency Reference Selection
• Select the input method for the frequency reference in 1st/2nd Frequency Reference Selection
(A001/A201).
• When the multi-step speed reference function is used (by setting the multi-function input terminals for
the Multi-step Speed Reference 0 to 15), the setting in A001/A201 is enabled only for the Multi-step
Speed Reference 0.
The values set in the Multi-step Speed Reference 1 to 15 (A021 to A035 ) are used as the frequency
references for the multi-step speed reference 1 to15.
• The frequency reference value selected in the 1st/2nd Frequency Reference Selection can be
checked in the Output Frequency Setting/Monitor (F001). In addition, when A001/A201 is set to 02
(Digital Operator (F001)), the frequency reference can be changed in F001.
• When the Multi-function Input 1 to 7 Selection is set to 31 (OPE: Forced operator function) or 51 (F-
TM: Forced terminal block), the setting has priority over the 1st/2nd Frequency Reference Selec- tion
(A001/A201) and 1st/2nd RUN Command Selection (A002/A202).
When each terminal is input, the frequency reference and RUN command from the Digital Operator
or the control terminal are enabled forcibly.
The values set in the Multi-step Speed Reference 1 to 15 have priority over the forced operator func-
tion and forced terminal block.
• When the Frequency Lower Limit (A062/A262) is set, the output frequency will be a frequency set by
the lower limit, even if the final frequency reference is set below the lower limit. Even if you set the
frequency reference to 0 Hz, the lower limit takes precedence, so turn OFF the RUN command to
make it stop.

*1. To enable the switching to the 2nd control, set one of the Multi-function Input 1 to 7 Selection (C001 to C007)
to 08 (SET) and turn ON that terminal.
*2. This setting is enabled when the Digital Operator with the volume control (Model: 3G3AX-OP01) is con-
nected.
*3. Refer to 7-5-7 Frequency Calculation Function on page 7-39.
