7-3. Spindle Judgment: Checking REJECT Reason
When a value falling outside the high and low limit range (Lower than the low limit or higher than the
high limit value) of a fastening parameter is detected during a fastening operation, the REJECT
judgment is made and the NG LED of the controller lights up red.
The reason for stopping that was detected first can be confirmed from the display.
●Confirmation of the Fastening Parameter
Procedure 1. After the end of fastening, “r.**” is indicated on the WORK Display of controller display
as shown in the figure above, with the numeral indicated at “**” being the parameter No. of
the last parameter used during operation (the parameter No. will not be updated unless a
fastening operation is performed).
●Confirmation of the Reason for Fastening Stoppage
Procedure 1. After the end of fastening, press the “▲” and “▼” buttons to select COUNT/D-No.: “09.”
The reason for the fastening stopping is indicated in the upper part of the display.
Procedure 2. If “REJECT” is indicated, the D-No. of the parameter set value for which the stop occurred
first is indicated at the COUNT/D-No. “10” as shown in the drawing above. Also, for each
item which a fastening REJECT (failure) is detected, “H/L” is indicated at the top digit of the
upper stage of the indicator indicating High or Low limit reject.
