Explanation:

The filter time constant digital filtering process on the input signal, in order to prevent the influence of the
interference signal on the system stablility.

If the filter time constant is too large, the control is stable, but control response is bad; if the filter time
constant is small, the response is fast, but the control may not be stable. If the best setting value is unknown,
you can appropriately adjust the setting value according to the unstable or response delay.

Notes:
 Only when the inverter operation command control mode (P0.07) is terminal control mode, two-wire 1 and 2,
three-wire 1 and 2 are meaningful.
 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
stop. If P2.38 is 0 (Prohibit reverse operation disabled), the inverter will run reverse. If FWD and REV are
valid or invalid at the same time, the inverter will stop. Terminals wiring is shown in Figure.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 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 Figure.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 Figure.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 Figure.4.
 In Figure. 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 Figure.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 SB1 to stop the inverter output.
