S: Direction switch; anticlockwise when effective
In the terminal control mode, whether single-wire mode ( 1 ) or two-wire mode (2), although they
are both level-effective, the restart of the inverter after a shutdown caused by a shutdown
command originating from other sources requires a shutdown signal prior to the emission of
operation signal.
For Two-Wire Mode 3 or Three-Wire Mode, the start button will be ineffective when the
NORMALLY OFF stop button is switched off.
Even if the operation mode defines the operation direction, the direction lock still overrides.
If the teminal command contains no information about direction, the operation direction will be
determined by the frequency channel settings (Positive/Negative).
CAUTION: When there is an operation signal and Fb-26 “Poweron Self-Restart Enabled”= 1
(factory settings), the inverter will start automatically after connection to power supply.

Debouncing Time of Digital Input Terminal: This function is used to define the debouncing
time of the digitally inputted signals. Signals with duration shorter than the debouncing time are
negligible.
