PIN NAME DESCRIPTION
14
WE2 STOP/
WELD COUNT
WE2 stop input or Weld count input pin.
When WE2 STOP is selected
Closing this pin during the WELD2 sequence will switch the sequence to COOL2.
Closing this pin in the sequence other than WELD2 is neglected. The sequence will
switch to COOL2 if this signal is closed during the WELD2 sequence operation.
When this pin is closed before WELD2 welding start after startup, the current is
supplied for at least a control cycle and WELD2 is stopped to switch the sequence to
COOL2.
When WELD COUNT is selected
This pin allows you to determine whether or not the number of deposited welds has
reached the WELD COUNT setting.
20ms or more is required for receiving the WELD COUNT input signal.
15
INT +24VDC GND
(I/O COM)
COM pin. This pin is internally connected to the +24VDC GND
16 STAGE1
1ST STAGE input pin. Closing this pin will close SOL1 of pin 36 or SOL2 of pin
37. Since the welding sequence does not start, you can adjust or check the position.
When the 2ND STAGE pin is closed after this, a welding can be done.
17 STAGE2 2ND STAGE input pin. Closing this pin will start the sequence.
18
THERMOSTAT
COM
Common input for Transformer Thermostat through the XFMR Sense connector
For Internal Sink operation, connect to INT +24VDC GND (I/O Com)
For internal Source operation, connect to INT+24VDC
For External Sink, connect to PLC COM For External source, connect to PLC +24V
19
WELD ON/OFF
Weld ON pin. Close this pin to turn ON the WELD ON/OFF signal, and open it to
turn it OFF.
Leaving this pin open will shut off welding current even when the sequence
operation is performed. Use this pin, for example, to start the sequence
experimentally.
20 THERMOSTAT
If the XFMR Sense connector is not used, this pin should be connected to the
appropriate voltage (Sink or Source) If the Sense connector is used this pin should
be left open.
21 FLOWSWITCH Flow switch input pin. Opening this pin will result in a flow rate error.
22
INT +24VDC GND
(I/O COM)
COM pin. This pin is internally connected to the +24VDC GND.
23
ERROR RESET
Error/caution reset input pin.
Eliminate the cause of error or caution and close this pin to reset the error or caution
indication.
20ms or more is required for receiving the input signal.
24 STEP RESET
Step reset input pin. Closing this pin while the STEPPER is ON will reset the STEP
number to 1.
20ms or more is required for receiving the input signal.
