Frequency Reference
Selection 1
Sets the input method for the frequency reference. 1
(0 - 3)
Note:
• Push on the keypad to set the input mode to HAND 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. Examine the setting for the frequency reference input and enter a value ≥ E1-09.
0 : Keypad
The bypass uses the keypad to enter the frequency reference and also switches the PID setpoint to YA-01 [Setpoint 1].
Use and on the keypad to change the frequency reference.
1 : Analog Input
The bypass uses MFAI on the bypass board to input an analog frequency reference with a voltage or current input
signal.
• Voltage Input
Refer to Table 5.18 to use a voltage signal input to one of the MFAI terminals.
