7.8.4 PVT compensate
In the Pset Programming + branch,
select PVT compensate.
Via the PVT compensate function, PF allows the P111 First target, P113 Final target and P114 Final tq max to
be compensated for the prevailing torque during the rundown phase.
The PVT compensation value is calculated at P116 Rundown complete as an average torque from an
interval preceding the P231 PVT comp point. The PVT compensation value is used as a base reference for
the torque used during tightening, and the torque levels can change dynamically for each new tightening.
When setting P231 PVT comp point larger than the total performed angle at rundown
complete, the tightening will be aborted and the error PVT compensate overflow is
triggered.
As default, the tightening results are presented with the compensation value subtracted, but can be
presented with PVT compensation value added by checking the box C503 Torque with PVT comp.
