Detected speed direction –
DSD
(Function code data = 116)
This signal shows the direction of the detected speed. The detected speed is assumed as positive in
FWD operation and negative in REV operation. If the detected speed is higher than F25,
DSD
is
turned ON. If the detected speed is smaller than (- F25),
DSD
is turned OFF.
F25 is the hysteresis
width.
The state is maintained when the detection speed is inside the hysteresis width.

Travel Direction Changes lifetime early warning –
TDCL
(Function code data = 121)
This output function will go from OFF to ON when L113 reaches the level set in L112. Function
L112 is a percentage of the limit set in L111.
When output function is in ON condition, and L113 becomes smaller than L111 percentage of L112,
output will go to OFF condition.
Lifetime early warning terminal function is linked to the light alarm
tCW
.
L112 set to 0% is understood as disabled. So in this case inverter will not show any warning, and
output will not go from OFF to ON even 120 (or 1120) is set.
For details, refer to the descriptions of function codes L109 to L115 (TDC) and L197. For
additional information, refer to related Application Note (AN-Lift2-0004v100EN).
■
Travel Direction Changes pulse –
TDCP
(Function code data = 122)
This ouput function generates a pulse each time that L113 counter is increased. In other words,
digital output generates a pulse each time that RUN command changes from FWD ro REV or from
REV to FWD.
When [EN1]/[EN2] terminal signals are not ON, pulse is not generated, as no real lift travel can be
performed.
This pulse has a duration of 0.5 s.
For details, refer to the descriptions of function codes L109 to L115 (TDC). For additional
information, refer to related Application Note (AN-Lift2-0004v100EN).
■
Short-circuit control –
SCC
(Function code data = 123)
SCC
output function is used to control motor phases short circuit device (mini contactor or power
relay).
This output function has to be wired to the control terminals (for example the coil) of the motor
phases short circuit device. Short circuit contact has to be a normally closed contact. In other words,
when inverter is not supplied, motor phases has to be short circuited. When SCC output function is
in ON state, voltage is applied to the short circuit device control terminals and it opens.
For details, refer to the descriptions of function codes L120 and L121.
