7-3. Axis Judgment: Checking the Contents of the REJECT
When a value falling outside the high and low limit range (falling below the low limit value) of a
fastening parameter is detected during a fastening operation, the REJECT axis judgment is made and
the NG LED of the controller 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 Parameter
Procedure 1. After the end of fastening, “r.**” is indicated at the WORK indication part of controller
indicator 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).
●Confirmation of Reason for Stopping of Fastening
Procedure 1. After the end of fastening, operate the “▲” and “▼” switches to select COUNT/D-No.: “09.”
The reason for stopping of the controller is indicated at the upper part of the indicator.
Procedure 2. If “REJECT” is indicated, the D-No. of the parameter set value for which stopping occurred
first is indicated at the COUNT/D-No. indication part “10” as shown in the drawing above.
Also, for each item for which a fastening NG (failure) is detected, “H/L” is indicated at the
top digit of the upper stage of the indicator.
