3-3. Start stop of the VFD
3-3-1. Start stop signal
There are three kinds of start stop signal sources of frequency converter, which are panel start stop, terminal
start stop and communication start stop. They are selected by function parameter P0-02.
3-3-1-1. Panel start stop
The key on the panel is used for command control, and the run key on the keyboard is pressed to start the
operation of the frequency converter; while the frequency converter is running, the stop key on the keyboard is
pressed to stop the operation of the frequency converter.

3-3-1-2. Terminal start stop
VH6 inverter provides a variety of terminal control modes. The switch signal mode is determined by function
code P2-10, and the input port of start stop control signal is determined by function code P2-00 ~ P2-09.
Example 1: Two-wire control, forward signal connected to X1, reverse signal connected to X2.
Example 2: 3-wire control, forward signal connected to X1, reverse signal connected to X2, stop signal
connected to X3.
3-3-1-3. Communication start stop
VH6 supports Modbus-RTU mode to communicate with the host computer. The built-in communication port of
frequency converter is Modbus-RTU slave protocol, and the host computer must use Modbus-RTU master
protocol to communicate with it.
