40: Deceleration DC braking
The terminal is used to make the AC drive decelerate to the start frequency of DC braking during stop
(F6-11) and then enter the DC braking state.
41: External stop terminal 1
When the running command source is the operating panel (F0-02 = 0), this terminal is used to stop the
AC drive.
42: External stop terminal 2
The terminal is used to make the AC drive decelerate to stop in any control mode (operating panel,
terminal, or communication control). In this case, the deceleration time is fixed to deceleration time 4
(F8-08).
43: Running pause
When the terminal is active, the AC drive decelerates to stop with all running parameters memorized
(such as the PLC, wobble, and PID parameters). When the terminal is inactive, the AC drive resumes
its status before stop.
44: Coast to stop
When the terminal is active, the AC drive stops output, and the motor coasts to stop under the action
of mechanical inertia.
45: Emergency stop
When the system is in the emergency state, the AC drive decelerates according to the deceleration
time for emergency stop set in F8-59, and it decelerates according to the minimum unit time when
the deceleration time for emergency stop is 0s in V/f mode. The input terminal does not need to be in
the closed state continuously. Even if it is closed for only an instant, an emergency stop will be
performed immediately.
Different from general deceleration, the emergency stop action prevents the AC drive from restarting
even if the emergency stop input terminal is opened after the deceleration time for emergency stop
expires and the run signal is still valid on the AC drive terminal. To restart the AC drive in this case,
disconnect the running terminal and input the run command.
46: Motor selection
The terminal is used to select the motor. When the terminal is active, motor 2 is selected. When the
terminal is inactive, motor 1 is selected.
47: Clear the current running time
The terminal is used to clear the current operation time of the AC drive.
If the current operation time is less than the setpoint (greater than 0) of F8-57 (current running time
threshold) and the terminal is active during this process, the current operation time is cleared.
If the current running time threshold is greater than the setpoint (greater than 0) of F8-57 and the
terminal is active, the current operation time is not cleared.
48: Switchover between two-wire and three-wire control
The terminal is used to switch between two-wire and three-wire control.
If F4-17 is set to 0 (two-wire mode 1), the AC drive switches to three-wire mode 1 when the terminal is
active.
If F4-17 is set to 1 (two-wire mode 2), the AC drive switches to three-wire mode 2 when the terminal is
active.
If F4-17 is set to 2 (three-wire mode 1), the AC drive switches to two-wire mode 1 when the terminal is
active.
If F4-17 is set to 3 (three-wire mode 2), the AC drive switches to two-wire mode 2 when the terminal is
active.
49: PLC state reset
The terminal is used to restore the AC drive to the initial state of the simple PLC.
