This parameter is enabled when H1-xx = 2 [MFDI Function Selection = External Reference 1/2 Selection] is
activated.
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 or equal to the value set in E1-09 [Minimum 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 more than
or equal to 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 A1 and A2 to input an analog frequency reference with a voltage or current input signal.
