Enable communications link via RS-485 or field bus (option) -- LE
(Function code data = 24)
Turning this terminal command ON assigns priorities to frequency commands or run
commands received via the RS-485 communications link (H30) or the field bus option (y98).
No LE assignment is functionally equivalent to the LE being ON. (Refer to H30
(Communications link function) and y98 (Bus link function.)

Run forward -- FWD (Function code data = 98)
Turning this terminal command ON runs the motor in the forward direction; turning it OFF
decelerates it to stop.
This terminal command can be assigned only by E98 or E99.
„
Run reverse -- REV (Function code data = 99)
Turning this terminal command ON runs the motor in the reverse direction; turning it OFF
decelerates it to stop.
This terminal command can be assigned only by E98 or E99.
