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 terminal 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
Current running duration
clear
The terminal is used to clear the current running duration of the AC
drive.
If the current running duration 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 running duration is cleared.
If the current running duration is greater than the setpoint (greater than
0) of F8-57 and the terminal is active, the current running duration 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.
50
Wobble pause
In the wobble process, when this terminal is active, the wobble function
is paused (the AC drive outputs at the center frequency).

4.3.2 Digital Output (DO)
4.3.2.1 Sources of DO Terminals
The drive unit of this product has no DO terminals and needs to map to output terminals of the power
supply unit or extension card. Therefore, you need to set the DO terminal sources when the drive unit
uses DO/RO terminals.
The DO terminal source is displayed in a way similar to that shown in “
4.3.1.1 Sources of DI Terminals
”
on page 458
when you modify related parameters on the operating panel. There are some differences
in the selection of DIOs of the power supply unit, which are described as follows.
