0: no function
Indicates that the terminal is invalid. If the terminal function is idle, it is recommended to set it to "0" to prevent
misoperation.
1: Forward running
When the running command is given by the terminal, if [F02.23] is set to "0: two-wire system 1", the inverter will run
forward when the terminal is valid. For other control modes, see parameter [F02.23]; Start the protection feature
reference parameter [F02.24].
2: Reverse running
When the running command is given by the terminal, if [F02.23] is set to "0: two-wire system 1", the inverter will run
in reverse when the terminal is valid. For other control modes, see parameter [F02.23]; Start the protection feature
reference parameter [F02.24].
3: Three-wire operation control (Xi)
When the running command is given by the terminal, if [F02.23] is set to "2(3): three-wire system 1(2)", the terminal
is the three-wire operation control terminal (Xi). For details, see parameter [F02. 23]; At the same time, the startup
protection feature is invalid. For details, see parameter [F02.24]
4: Forward turning
5: Reverse jog
Positive and negative jog command input port. When this terminal is valid, the inverter will jog. The terminal jog
command has the highest priority. See [F01.38~F01.40] for detailed setting of jog parameters and reference parameter
[F02.24] for jog protection characteristics.
6: Free parking

AC300 Series Vector Control Inverter Manual
When the terminal is valid, the inverter immediately blocks the output, and the motor is in free running state.
When the free stop terminal is always active, the drive will not accept any start command and remain stopped.
When the keyboard, RS485, optional card and terminal three-wire control are running, after the free stop
terminalcommand is released, the original operation command will not be restored. If the inverter needs to be started,
the operation command must be re-entered.

7: Emergency stop

If an emergency stop command is input during the operation of the inverter, the inverter will decelerate to a stop with
the deceleration time set by [F01.27]. For details, please refer to [F01.27] Emergency stop deceleration time.
After entering the emergency stop command, it cannot be re-run until the inverter has completely stopped. If the stop
mode [F01.10] is set to free stop, the inverter will still perform emergency stop deceleration according to the emergency
stop time.
When the emergency stop terminal is always active, the inverter will not accept any start command and keep the
stop command status. When the terminal two-wire control is running, whether the original operation command is
restored after the emergency stop terminal command is released, refer to the parameter setting of [F02.24].
When the keyboard, communication, optional card and terminal three-wire control are running, the original stop
command is not restored after the emergency stop terminal command is released. To start the drive, you need to
re-enter the run command.
Emergency stop command diagram
Notes: Sudden deceleration can cause the inverter to generate an overvoltage fault. When an overvoltage fault
occurs, the output of the inverter will be cut off and the motor will run freely, which will cause the motor to be
out of control. Therefore, when using the emergency stop function, set the appropriate deceleration time in
[F01.27] or use it with the energy consumption brake function.

8: Fault reset

When the inverter has a fault alarm, the fault can be reset through this terminal. When the two-wire control of the
terminal is running, whether the original operation command is restored after the fault is reset, refer to the parameter
setting of [F02.24].

9: External fault input

Through this terminal, the fault signal of the external device can be input, which is convenient for the inverter to
