Maximum number of travel direction changes allowed. Where 0.01
means 10.000 changes and 10.00 means 10.000.000 changes.

Travel direction counter (Warning level) (L112)
A warning level can be set in this parameter ( TDCL ). When counter L113 reaches the percentage set
in this function code, output function TDCL will go to ON state. On the other hand, inverter will
indicate the light alarm tCW (L197 bit0).

Tripping level of TDCL output function and light alarm. Percentage
level is refered to L111 limit.
■
Travel direction counter (Partial number of direction changes) (L113)
Partial number of direction changes is shown in this parameter. When running direction is changed
from FWD to REV , or from REV to FWD , and inverter in enabled (EN terminal ON), L113 counter
is increased one unit.
Data for L113 Action
OFF Disabled
0.01~10.00 Million
direction changes
Maximum number of travel direction changes allowed. Where 0.01
means 10.000 changes and 10.00 means 10.000.000 changes.
This parameter can be modified and has to be set to 0.00 when suspension means has been changed.
When this parameter is modified (value is changed) reset counter (L115) is increased one unit.
By definition, this parameter cannot be bigger than L111 limit. When L113=L111 inverter will trip
with tCA alarm, in this case, please change suspension means and reset the counter.
After modifying L113 counter, make sure function is locked again. To do so, please turn
the power supply of the inverter OFF, wait until keypad is unlit and switch ON again.
In figure 1, a basic time chart of TDC function is shown. In this case, L111 limit is set to 3. As it can
be observed, several travels in forward (up) and reverse (down) direction are shown. When direction
is changed from up to down, or from down to up, L113 counter increases one unit. At the same time,
an output programed with the function TDCP outputs a pulse. On the other hand, even starting a new
travel, if direction is not changed, nothing changes on outputs or counter. In this example L112 is set
to 60%. When L113 counter reaches the value 2, which corresponds to the 66.66% of travel limit, an
output programed with the function TDCL changes from OFF to ON. At same time, light alarm for
pre warning is shown in the keypad ( tCW ). When L113 counter reaches the value 3, inverter is
blocked by the alarm tCA . Even forward or reverse are activated, inverter will not allow any other
travel until suspension means are changed and L113 counter is reset.
