FEC HFC3000 - NG Judgment

Chapter 6 Description of Operations
PAGE 6-26
6-5-2. NG Judgment
Judgments by the high and low limit values of torque, angle, time, and rundown revolutions are
performed during the fastening operation or after the end of fastening. The REJECT axis judgment is
made if a fastening result falls outside the high or low limit range.
* High and Low Limit Standard Values for Output Judgment
The high and low limit values of the HFC3000 System are as follows.
・High limit standard value (REJECT): A value exceeding the high limit standard value
・High limit standard value (ACCEPT): A value that is no more than the high limit standard value
・Low limit standard value (REJECT): A value less than the low limit standard value
・Low limit standard value (ACCEPT): A value that is no less than the high limit standard value
REJECT < Low Limit Standard Value ≤ ACCEPT ≤ High Limit Standard Value < REJECT
Be careful as the output judgment is not performed regardless of the high and low
limit set values when the settings of the fastening parameters D-No. 003 “Judge
Item 1” and D-No. 004 “Judge Item 2” are 0.
