6. Selection of RUN/STOP/FWD/REV control command
Before start running the inverter, the most important step is to select the
Control Command Source
. You can choose
whether the control command will
come from panel or terminal.
If the control command should come from terminal, then the two input terminals
RUN
and
REV
are used for controlling the
inverter.
These two input terminals are
OFF
when left open and will be
ON
when connected to
DCOM
terminal.
Parameter Pr.39 is used to select the source of Control Command.
CMD_SELECT Pr.39 = a. b, is composed of two selections "a" and "b" in one parameter,
If DIx(89) or DIx(90) is ON, then CMD_SELECT="b", else CMD_SELECT="a".
Refer to DIx(89) and DIx(90).
If CMD_SELECT=0
The RUN and REV terminals are disabled.
Control Command will come from the
keypad panel
.
Push
FWD key
, the inverter will run forward direction.
Push
REV key
, the inverter will run forward direction.
If CMD_SELECT=1
The
RUN
terminal will start the inverter running, and
REV
terminal controls the
running direction.
If CMD_SELECT=2
The
RUN
terminal is equivalent to
FORWARD-RUN
.
The
REV
terminal is equivalent to
REVERSE-RUN
.
If CMD_SELECT=3
Similar to mode-1, but will check
RUN terminal at OFF
position while power on.
If CMD_SELECT=4
Similar to mode-2, but will check
RUN & REV at OFF
position while power on.
If CMD_SELECT=5 (for PDAN series only)
When RS485 port is defined as JPS protocol, RUN/STOP command comes from RS485 Serial Port.
Note: Refer to Sec.7 concerning how to determine the running frequency.

Similar to Mode-1, When after RESET, if RUN terminal is not in OFF position, the inverter will
show "--on”, warning the user to remove the control signal.
4
Similar to Mode-2, When after RESET, if RUN and REV terminals are not in OFF position, the
inverter will show "--on”, warning the user to remove the control signals.

When RS485 port is defined as JPS protocol, RUN/STOP command comes from RS485 Serial Port.
(For PDAN series using JPS protocol only)
