(0 - 4)
Note:
• Push on the keypad to set the input mode to LOCAL and enter the frequency reference from the keypad.
• When the drive receives a Run command when the frequency reference is 0 Hz or less than the E1-09 [Minimum Output Frequency]
value, on the keypad will flash. Check 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.
Use and on the keypad to change the frequency reference.
1 : Analog Input
Use MFAI terminals A1, A2, and A3 to input an analog frequency reference with a voltage or current input signal.
• Voltage Input
Refer to Table 11.22 to use a voltage signal input to one of the MFAI terminals.
