Notes on Parameter Initialization
The parameters shown in Table i.33 will not be reset when the drive is initialized by setting A1-03 = 2220 or 3330. Although
the control mode in A1-02 is not reset when A1-03 is set to 2220 or 3330, it may change when an application preset is selected.

b1-01: Frequency Reference Selection 1
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. However, the RUN indicator LED will light in zero speed
control when A1-02 is set to 3, 4, or 6.
2. Press the LO/RE key to set the drive to LOCAL and use the operator keypad to enter the frequency reference.
No. Parameter Name Setting Range Default
b1-01 Frequency Reference Selection 1 0 to 4 1
Setting 0: Operator keypad
Using this setting, the frequency reference can be input by using 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.
Switching between Main/Auxiliary Frequency References
The frequency reference input can be switched between the analog terminals A1, A2, and A3 using multi-speed inputs. Refer
to Multi-Step Speed Selection on page 74 for details on using this function.
Setting 2: MEMOBUS/Modbus Communications
This setting requires entering the frequency reference via the RS-485/RS-422 serial communications port (control terminals
R+, R-, S+, S-).
Setting 3: Option card
This setting requires entering the frequency reference via an option board plugged into connector CN5-A on the drive control
board. Consult the option board manual for instructions on integrating the drive with the communication system.
Note: If the frequency reference source is set for Option PCB (b1-01 = 3), but an option board is not installed, an oPE05 operation error will be
displayed on the digital operator and the drive will not run.
Setting 4: Pulse Train Input
This setting requires a pulse train signal to terminal RP to provide the frequency reference. Follow the directions below to
verify that the pulse signal is working properly.
Verifying the Pulse Train is Working Properly
• Set b1-01 to 4 and set H6-01 to 0.
