4.6 Basic Drive Setup Adjustments
2220: 2-Wire Initialization
Returns all parameters to factory default values for 2-Wire control. A 2-Wire sequence
assigns functions to input terminals S1 and S2.
3330: 3-Wire Initialization
Returns all parameters to factory default values for 3-Wire control. A 3-Wire sequence
assigns functions to input terminals S1, S2, and S5.
5550: Uploads Parameter Data from the Removable Control Circuit Terminal Board
Replacing either the removable control circuit terminal board or the drive and applying
main power may result in an oPE04 fault. If parameter setting data in the removable
control circuit terminal board is correct, set A1-03 to “5550” to upload the data to the
drive.
Note: Refer to Run Command Input Selection: b1-02 on page 103 for more information on a 2-Wire and 3-
Wire sequence.
Note: Initializing the drive for 2-Wire sequence (A1-03 = 2220) returns all drive parameters to factory settings.
Back up all parameters in the event of accidental initialization. the data with 2-Wire sequence returns all
the set parameters to the factory settings.

Frequency Reference Source: b1-01
This section explains how to assign the frequency reference. Parameters b1-01 and b1-
02 can be used to select the source of the run command and the frequency reference
independently (e.g., set the reference from the operator and set the run command from
the terminals).
■
Frequency Reference from the LED Operator: b1-01 = 0
When b1-01 = 0 the frequency reference will be provided by the LED operator. Refer
to The Drive and Programming Modes on page 81 for information on how to set the
frequency reference.
■
Frequency Reference from the Analog Input Terminal: b1-01 = 1
When b1-01 = 1, analog inputs A1 and A2 provide the frequency reference.
Note: Set H3-02 (Terminal A1 Function Selection) to “0” to congure Terminal A1 for the main analog frequency
reference.
Using a Single Analog Signal (V or I) as the Frequency Reference
Control Circuit Terminal A1 (Voltage Input):
When entering the main frequency reference with a voltage signal, use the voltage input
set up in control circuit terminal A1.
