2-Wire/3-Wire Operation Control

Settings
The VFD-V drive offers six types of external operation control.
Three of six methods include a "Line Start Lockout" feature. When Line
the
start lock out is enabled, the drive will not recognize a RUN command upon
power up. The VFD-V must see the terminal state change from low to high.
This is a safety feature for applications where applying power does not
determine a RUN command.
The Line Start Lockout feature does not guarantee the motor will never start under this
condition. It is possible the motor may be set in motion by a malfunctioning switch.
