◆The listed functions above are only valid when P0.04 is set to 1, 2 or 5 (terminal
control).
◆2-wire control mode 1
FWD, REV: Running 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 valid, run forward; if REV is valid and P2.26 is set to 1
(Prohibit reverse operation enabled), The ac drive will stop. If P2.26 is 0 (Prohibit
reverse operation disabled), the ac drive will run reverse. If FWD and REV are valid or
invalid at the same time, the ac drive will stop. Terminals wiring is shown in Fig.1
◆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 ac drive will startup. If F/R is selected but disabled, the ac drive
will run forward. If F/R is selected and enable, the ac drive will run reverse. When F/R
is not selected, the running direction is defined by function code. If RUN is disabled,
the ac drive 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 ac drive will run forward; If REV is enabled, the
ac drive will run reverse. If FWD and REV are enabled or disabled, the ac drive will
stop.
If HLD is ON, FWD and REV signal will self-hold. If HLD is OFF, the ac drive 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 ac drive will startup. If F/R is selected but disabled, the ac drive
will run forward. If F/R is selected and enable, the ac drive will run reverse. When F/R
is not selected, the running direction is defined by function code. If RUN is disabled,
the ac drive 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.
