5-5 Frequency Reference Settings
• Select the input method for the frequency reference.
• 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 value set in A001 is effective only for the Frequency
Reference 0.
The values set in the Frequency Reference 1 to 15 have priority over the value set in A001.
*1 This setting is enabled when the 3G3AX-OP01 is connected.
Below are the details of the parameter data.
*1 Refer to 6-2 Sensorless Vector Control on page 6-4 .
*2 Refer to “DriveProgramming User’s Manual (I580)”.
*3 Refer to Calculation Frequency Function on page 7-59.
