External Output Signals
The following signals can be assigned on the
OUTPUT SELECT
screen to output pins 28 to 32 (OUT1
to 5)
NAME DESCRIPTION
END
Closed each time the sequence is complete and output the END signal.
Output time selection (10 to 200ms, HOLD)
When the off time (OFF) is set and the END signal time is set to time longer than OFF time, the END
signal time will be equal to OFF time.
COUNT
ERROR
Weld count error output.
In the case WELD COUNT is ON, this signal is closed when the weld count terminal is open before
the set number of welds is not deposited. This signal is also closed when the weld count terminal is
open before welds are counted. When the weld count is larger than the set number of welds, this
signal is not output.
To clear the count error signal, you need to input the weld count signal again or add required number
of welds to make up for insufficiency.
The count error signal is not cleared if the error reset signal is input. Also, when required number of
welds are added to make up for insufficiency, the count error signal is output until the insufficient
number of welds is complete.
READY Closed when no error occurs and the WELD ON/OFF is ON.
STEP END
Closed when the last step ends in step-up operation.
Closed until the step reset signal is input or the step setting (value) is changed.
Even if VALVE1 and VALVE 2 are switched, the signal remains closed when the either one reaches
the set number of welds. The error is displayed only when the VALVE where the current is supplied
has reached (reaches) the set number of welds.
WELD SIGNAL
Welding timing signal. Closed during welding. No output at COOL. Closed even if start with the
WELD OFF state (with time set and HEAT not set).
GOOD
Closed when the measured value is judged to be within the range set on the MONITOR SET screen
after the completion of welding sequence.
Output time selection: 10 to 200ms, 0ms (Hold)
COUNT UP
Closed when the count reaches the preset counter value. To cancel the count up output, input the reset
signal to the count reset pin.
OUT I WELD1 weld end output. Closed between the WELD1 weld end and the beginning of HOLD.
OUT II WELD2 weld end output. Closed between the WELD2 weld end and the beginning of HOLD.
