[Classification] Contact signal input
LDI01 to LDI04 can be switched between 24 V
common voltage and 0 V common voltage. LDI05
and LDI06 are tied to 24 V common voltage.
[Function] Six input signals are provided as interface signals.
These can be used, for example, for checking whether
the hand mounted on the tip of the loader is open or
closed. These signals can be used for general purpose
applications, depending on the function demanded of
the mechanical unit of the loader. When an
incremental pulse coder is used, and a reference
position return operation is needed, LDI01 to LDI04
are used as deceleration signals *DEC1 to *DEC4.
These signals are directly referenced by the CNC that
exercises loader control. When, however, skip
operation is not required, the PMC can use these
signals for general purpose applications.
[Classification] Common voltage selection
[Function] When COMLD is connected to 0V, LDI01 to LDI04
function as 24 V common voltage input signals.
When COMLD is connected to +24E, LDI01 to
LDI04 function as 0 V common voltage input
signals. Note that the signal polarity also changes
accordingly. That is, when LDI01 to LDO04 are
functioning as 24 V common voltage signals, logic
1 corresponds to the contact being closed; when
LDI01 to LDO04 are functioning as 0 V common
voltage signals, logic 0 corresponds to the contact
[Classification] Transistor sink output, 24 V/200 mA load
[Function] For the control of operations such as opening/closing
the hand mounted on the tip of the loader and air
blow, 8 output signals are provided. These signals
can be used for general purpose applications as
