Frequency Reference Source: B1-01 - YASKAWA V1000 Quick Start Manual

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 109
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).
n Frequency Reference from the LED Operator: b1-01 = 0
When b1-01 = 0 the frequency reference will be provided by the LED operator.

reference.
n 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 configure 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.
