Description
Fastening cycle time exceeds programmed Cycle Abort time value.
Spindle stopped by either the operator or other device.
Spindle stopped due to torque achieving greater than 115% torque limit for the
tool.
The tool shutoff due to a Fault. "See Chapter For your safety [} 10]".
Spindle stopped due to a stall.
Spindle failed fastening cycle due to a synchronization error.
Primary and secondary redundant transducer values are outside comparative
limits.
Primary and secondary redundant angle values are outside comparative limits.
Spindle stopped due to torque dropping below Torque Drop Threshold
Spindle stopped due to bailout on detecting yield during an Angle Control strategy.
A torque/angle window violation for the Torque Monitoring portion of the fastening
cycle.
Torque Rate has exceeded the High Limit or not achieved the Low Limit during a
Rate
Current value exceeds the high limit or not achieved the low limit.
That Led to Solution
Torque Target is close to
High Torque
No downshift
SC Series Controllers
Troubleshooting
To Clear/Reset from
Fault Condition
Increase High Torque
Add a within step
downshift or turn on ATC
or ATC+ to the audit step
