IS-300CA INVERTER POWER SUPPLY
B-12 990-418
Internal I/O Terminal Block
Pin No. Name
EtherNet/IP TM
Model
Description
1 INT.24V
24 V DC present.
When using a contact, open collector (sink type), or PLC
(programmable logic controller) as an input signal (e.g., for startup or
schedule selection), connect pins 1 and 2 together.
Note: Do not use pin 1 unless it is connected to pin 2 or 3. Failure to
observe this precaution will result in a malfunction.
2 EXT.COM
When using a contact, open collector (sink type), or PLC
(programmable logic controller) as an input signal (e.g., for startup or
schedule selection), connect pins 1 and 2 together.
When using an external power supply as an input signal, open pin 1
and connect pin 2 to the positive pin of the DC power supply or the
COM pin.
3 STOP
Normally, connect pins 3 and 1.
Closing this pin will cause an error message to appear, stopping
operation.
Open this pin when you wish to stop the sequence halfway through
when using starting signal self-hold input. Open for 20ms or more
when stopping.
4 COM COM pin. This pin is internally connected to the GND chassis.

WE1 STOP/
PARITY
YES
WE1 stop input or Parity input pin.
Switch between functions via the mode select settings (
refer to
Chapter 3, Section 10, Mode Select Screen
).
When WE1 STOP is selected
Closing this pin during the WELD1 sequence will switch the sequence
to COOL1.
The interrupt error occurs when the WELD1 STOP signal is input
before the start signal is input.
When this pin is closed before WELD1 welding start after startup, the
current is supplied for at least a control cycle and WELD1 is stopped
to switch the sequence to COOL1.
When PARITY CHECK is selected
This pin allows for detection of failure resulting from a wire break in
the schedule selection signal lines. Be sure that the total number of
closed schedule selection and parity signal lines is always odd.
