Setting 2220: 2-Wire Initialization
Resets parameters except parameters listed in Table 4.5 to default settings with digital inputs S1 and S2 configured as Forward
run and Reverse run, respectively.
Setting 3330: 3-Wire Initialization
Resets parameters except parameters listed in Table 4.5 to default settings with digital inputs S1, S2, and S5 configured as
Run, Stop, and Forward/Reverse respectively.
Setting 5550: oPE04 Reset
An oPE04 error appears on the digital operator when a terminal block with settings saved to its built-in memory is installed
in a drive that has edited parameters. Set A1-03 to 5550 to use the parameter settings saved to the terminal block memory.
Notes on Parameter Initialization
The parameters shown in Table 4.5 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, 6, or 7.
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
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 Table 4.6 for the input
used.
