10-10 Axis Judgment: Checking the Reason for a REJECT
When a value falling outside the high and low limit values (falling below the low limit value) of a fastening
parameter is detected during a fastening operation, the REJECT axis judgment is made and the JUDGE
LED of the Unit lights up in red. Also, the reason for stopping of fastening that was detected first can be
confirmed from the indicator.
● Confirmation of the Fastening Parameters (Sequence)
Procedure 1. After the end of fastening, “r.**” is indicated at the PAR No. indication part of the display as
shown in the drawing above, with the numeral indicated at “**” being the parameter No. of
the last parameter used for operation (the parameter No. will not be renewed unless a
fastening operation is performed).
Procedure 2. To confirm the sequence No. used for operation, the D-No. value is changed by operating
the “▲” and “▼” pushbuttons. When “33” is selected as the D-No. indicated at the D-No.
indication part, the numeral indicated at “**” of “S. **” at the upper part of the display is the
sequence No. used for operation (only indicated at the MASTER Axis).
● Confirmation of Reason for Stopping of Fastening
Procedure 1. When after the end of fastening, the “▲” and “▼” pushbuttons are operated to select “09”
as the D-No. indicated at the D-No. indication part, the reason for stopping will be indicated
at the upper part of the display.
Procedure 2. If “REJECT” is indicated, the D-No. of the parameter set value for which stopping occurred
first is indicated at the D-No. indication part “10” as shown in the drawing above. Also, for
each item for which a fastening REJECT (fail) is detected, “H/L” is indicated at the top digit
of the upper stage of the display.
Please refer to PAGE 8-10 concerning the details of the respective items indicated after the
end of fastening.
