The Up direction is automatically selected internally when a
speed input is given and the digital input for the down
direction will have priority. When the speed input is dropped at
the floor, the direction is internally dropped. This function is

When Up and Down functions are programmed to digital
inputs (LI04-11), the digital hardware input AND the Control
Word (serial speed control, FB01) direction bit must be set for
the direction to be active. The hardware direction must match
the software direction. If both Up and Down are signaled, a
Although the actual direction is determined by the signed
serial speed command (FB02 Field Bus Speed), the sign must
match the direction when utilizing LC01 Control Mode with

Control Type = Binary Speed Selection (1). This parameter must be adjusted as a
hexadecimal number using the NUM function on the keypad operator when editing.
To select this function, set LI03 Speed Input Decoding = Decode with LI16. Speeds are
