Note:
• Push on the keypad to set the input mode to LOCAL and use the keypad to enter the frequency reference.
• If the frequency reference is 0 Hz or less than the value set in E1-09 [Min Output Frequency] and the drive receives the Run command,
the RUN LED on the keypad will flash. Examine the setting for the frequency reference input and enter a value ≥ E1-09.
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 AI1 and AI2 to input an analog frequency reference with a voltage or current input signal.
• Voltage Input
Refer to Table 12.6 to use a voltage signal input to one of the MFAI terminals.
