4.6 Basic Drive Setup Adjustments
b1-01: Frequency Reference Selection 1
n
Selects the frequency reference source 1 for the REMOTE mode.
Note: 1. If a Run command is input to the drive but the frequency reference entered is 0 or below the minimum frequency, the RUN indicator
LED on the digital operator will light and the STOP indicator will flash.
2. Press the LO/RE key to set the drive to LOCAL and use the operator keypad to enter the frequency reference.
No.
b1-01
Setting 0: Operator keypad
Using this setting, the frequency reference can be input by:
• switching between the multi-speed references in the d1-oo parameters.
• entering the frequency reference on the operator keypad.
Setting 1: Terminals (analog input terminals)
Using this setting, an analog frequency reference can be entered as a voltage or current signal from terminals A1, A2, or A3.
Voltage Input
Voltage input can be used at any of the three analog input terminals. Make the settings as described in
used.
