Input Signals
STOP: Emergency Stop Signal
RESET: Reset Signal
REVERSE: Tool Reverse Rotation Signal
START: Fastening Start Signal
SELF CHECK DISABLE: Torque Transducer Self-Check Disable Signal
PAR SELECT BIT 0 to 4: Parameter No. Select Signals (BIT)
SEQ SELECT BIT 0 to 4: Sequence No. Select Signals (BIT)
Please refer to “Description of Input and Output Signals” in Section 4-6 regarding the above signals.
CYCLE COUNT CLEAR: Sequence Cycle Counter Reset Signal
When the CYCLE COUNT CLEAR signal is set to “ON” with the sequence counting method set as
“Signal Input,” the cycle count of the selected sequence No. is cleared. The sequence cycle count is
set to 1 at the start of the next fastening operation. The sequence counting method is changed using
the AFC3000 User Console (the factory setting is “Automatic Count Up”).
CYCLE COUNT UP: Sequence Cycle Counter Increment Signal
When the CYCLE COUNT UP signal is set to “ON” with the sequence counting method set as “Signal
Input,” the cycle count of the selected sequence No. is incremented by 1. Each time the CYCLE
COUNT UP signal is set to “ON,” the sequence cycle count is incremented by 1.
･ If “Automatic Count Up” is set as the sequence cycle counting method, the
cycle count is incremented by 1 when the SEQ judgment is “ACCEPT,”
“REJECT,” or “ABNORMAL” (with the exception of ABN10-*).
･ If the operation ends with a SEQ judgment besides the above, the cycle count
is not incremented and the same cycle count as the previous count is output
when the next sequence operation is started.
