◆2-wire control mode 2
In this mode, both function RUN (Run command) and F/R (Running direction) are used:
If RUN is enabled, the inverter will startup. If F/R is selected but disabled, the inverter
will run forward. If F/R is selected and enable, the inverter will run reverse. When F/R
is not selected, the running direction is defined by function code. If RUN is disabled,
the inverter will stop. Terminals wiring is show in Fig.2
◆3-wire control mode 1
FWD, REV: Run at preset direction. FWD means running forward, and Rev means
running reverse. You can control the motor’s running direction by switch terminal
FWD and REV. If FWD is enabled, the inverter will run forward; If REV is enabled, the
inverter will run reverse. If FWD and REV are enabled or disabled, the inverter will
stop.
If HLD is ON, FWD and REV signal will self-hold. If HLD is OFF, the inverter will
release self-holding and stop. Terminals wiring is show in Fig.3
◆3-wire control mode 2
In this mode, both function RUN (Run command) and F/R (Running direction) are used:
If RUN is enabled, the inverter will startup. If F/R is selected but disabled, the inverter
will run forward. If F/R is selected and enable, the inverter will run reverse. When F/R
is not selected, the running direction is defined by function code. If RUN is disabled,
the inverter will stop. If HLD is ON, RUN signal will self-hold. If HLD is OFF, the
self-holding will be released. Terminals wiring is show in Fig.4.
◆In Fig. 3, SB1 is Stop button, SB2 is running forward button. Press SB2 or SB3 to
startup the inverter, and switch SB2, SB3 to change the running direction. Press SB1 to
stop the inverter output.
◆In Fig.4, SB1 is Stop button, SB2 is running button, and K is running direction button.
Press SB2 to startup the inverter. Press switch K to change the running direction. Press
