Three-line control
The terminal determines three-line control of the AC drive. For
details, see the description of P4-11.

Forward JOG
（
FJOG
）
FJOG indicates forward JOG running, while RJOG indicates
reverse JOG running. The JOG frequency, acceleration time and
deceleration time are described respectively in P8-00, P8-01 and
P8-02.

Terminal UP
If the frequency is determined by external terminals, the terminals
with the two functions are used as increment and decrement
commands for frequency modification.
When the frequency source is digital setting, they are used to
adjust the frequency.

Terminal DOWN
8
IGBT Enable
In all elevator applications, an Output Contactor is installed
between the inverter output U, V, W and the motor. In an
emergency, the Safety Line is opened due to an unsafe condition
and the Output Contactor disconnects the power from the inverter
to the motor (the motor brake is also applied at the same time).
When the Output Contactor opens with current flowing through to
the motor (inverter IGBTs are active), there will be arcing in the
Output Contactor depending on the motor inductive energy. Arcing
of the Output Contactor can reduce the lifetime of the contactor
and in some severe cases can damage the contacts poles.
Therefore it is recommended to electronically switch off the
inverter IGBT firing circuits before opening the Output Contactor
(milliseconds later).
9
Fault reset (RESET)
The terminal is used for fault reset function, the same as the
function of RESET key on the operation panel.
Remote fault reset is implemented by this function.
10
RUN pause
The AC drive decelerates to stop, but the running parameters are
all memorized, such as PLC, swing frequency and PID
parameters. After this function is disabled, the AC drive resumes
its status before stop.
11
Normally open (NO) input
of external fault
If this terminal becomes ON, the AC drive reports Err15 and
performs the fault protection action. For more details, see the
