Frequency Reference
Selection 1
Sets the input method for the frequency reference.
0
(0 - 3)
Note:
• The RUN light on the keypad will flash if the Run command is entered when the frequency reference is 0 Hz or below the value set in
E1-09 [Minimum Output Frequency]. Examine the setting for the frequency reference input and enter a value more than or equal to the
E1-09 value.
0 : Keypad
Use the keypad to enter the frequency reference.
The frequency reference can be changed by using and on the keypad.
1 : Digital Input
Use the MFAI terminals A1, A2, and A3 to input an analog frequency reference with a voltage or current input
signal.
• Voltage Input
Refer to this table to use a voltage signal input to one of the MFAI terminals.
