4.5 Basic OperationThis section explains the basic settings required for initial drive operation. Checking thesebasic parameter settings during start-up will help to ensure a successful drive start-up.If more information is required for parameters not listed in this section, Refer to ParameterList on page 197 as required for a complete listing of drive parameters.u Initialize Parameter Values: A1-03Parameter A1-03 (Initialize Parameters) resets all parameters to the original default values.Note: Record all the changed settings before initializing parameters.n Different Methods of Drive initialization2220: 2-Wire InitializationReturns all parameters to factory default values for 2-wire control.3330: 3-Wire InitializationReturns all parameters to factory default values for 3-wire control.u Frequency Reference Source: b1-01This section explains how to assign the frequency reference. Parameters b1-01 and b1-02 canbe 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 = 0When b1-01 = 0 the frequency reference will be provided by the LED operator. Refer to TheDrive and Programming Modes on page 78 for information on how to set the frequencyreference.n Frequency Reference from the Analog Input Terminal: b1-01 = 1When b1-01 = 1, analog input A1 provides the frequency reference.Note: Set H3-01 (Terminal A1 Function Selection) to “0” to configure Terminal A1 for the main analog frequencyreference.Voltage InputWhen entering the frequency reference with a voltage signal, set parameter H3-01 to “0” for0 to 10 Vdc with lower reference limit. Set H3-01 to “1” if 0 to 10 Vdc input without lowerlimit is required. Set DIP Switch S1 for voltage input (position “V”).4.5 Basic OperationYASKAWA ELECTRIC TOEP C710606 25B YASKAWA AC Drive J1000 Installation & Start-Up Manual 874 Start-Up Programming& Operation
