
b1-01: Frequency Reference Selection 1
Use parameter b1-01 to select 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.
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
Input the frequency reference using the operator keypad with this setting.
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
input used.
