Run forward 2 -- FWD2 (Function code data = 88)

Turning the FWD2 ON runs the motor in the forward direction; turning it OFF decelerates it
to a stop.
The FWD2 can be assigned by any of E01 to E07, E98 and E99.
Run reverse 2 -- REV2 (Function code data = 89)

Turning the REV2 ON runs the motor in the reverse direction; turning it OFF decelerates it to
a stop.
The REV2 can be assigned by any of E01 to E07, E98 and E99.
Run forward -- FWD (Function code data = 98)

Turning the FWD ON runs the motor in the forward direction; turning it OFF decelerates it to
a stop.
The FWD can be assigned by E98 or E99 only.
Run reverse -- REV (Function code data = 99)

Turning the REV ON runs the motor in the reverse direction; turning it OFF decelerates it to
a stop.
The REV can be assigned by E98 or E99 only.
No function assigned (Function code data = 100)

Use this when no function is to be assigned to general-purpose, digital input terminals or the
customizable logic function disables terminal functions.
Flowrate switch -- FS (Function code data = 131)

Turning the FS ON uses the flowrate sensor as a flowrate switch for detecting the dry pump
or the end of curve.
 Refer to J163 through J166.
Filter clogging reverse rotation command -- FRC (Function code data = 132)

Turning the FRC ON activates the filter clogging prevention to run the motor in the forward
and reverse directions repeatedly according to the reverse rotation running time (J194).
 Refer to J188 through J196.
Switch PID channel -- PID2/1 (Function code data = 133)

The PID2/1 switches between PID control 1 (J101 through J131) and PID control 2 (J201
through J231).
 Refer to J101 through J131 and J201 through J231.
Switch to fire mode -- FMS (Function code data = 134)

Turning the FMS this terminal command ON switches to the fire mode to be used in an
emergency, in which the inverter runs the motor at the predetermined speed.
 Refer to H116 through H121.
