<Peak Torque Check – Torque Control>
Torque checking is a continuous process whenever the System is operating. Peak Torque Check uses
the maximum torque value detected during Fastening.
P
In Torque Control method, the Peak Torque High and Low Limits are set based upon the
engineering specification for the specific fastener. The High Final Angle limit will stop the fastening
process if it is reached before reaching the desired Standard Torque value.
