9.11.5 TORQUE RATE REJECT conditions
TorquE RAte (RAte) is defined as the change in torque divided by the change in degrees of
rotation (ANgle) during a specific interval.
1ST RATE
1.
A "RED" 1ST RATE Reject LED on the AXIS unit indicates that the Torque Rate, as
measured from Threshold (THR) to 1st TORque, is above the high limit specified in
the PARameters. May cause a LOW TOrque Reject.
2.
AN "ORAnge" 1ST RATE Reject LED on the AXIS unit indicates that the Torque
Rate, as measured from THR to 1st TOrque, is below the low limit specified in the
Parameters. MAy cause a LOW Torque Reject.
2ND RATE
1.
A "RED" 2ND RATE Reject LED on the AXIS unit indicates that the Torque Rate, as
measured from 1st TORque to CROSSOVER RAte 2 Torque, is above the high limit
specified in the Parameters. May cause a LOW TORQUE REJECT.
2.
AN "ORANGE" 2ND RATE Reject LED on the AXIS unit indicates that the torque
RATE, as measured from 1st TORque to CROSSOVER RAte 2 Torque, is below the
low limit specified in the PArameters. MAY cause a LOW TORQUE REJECT.
CAUSES of HIGH RATE Rejects:
Reduced lubrication, thread obstacle, reduced joint compression.
CAUSES of LOW RATe Rejects:
EXcessive lubrication, thread obstacle, excessive joint compression.
