6.5.3.4 Min Torque Restriction
Parameters
: Threshold torque TStart, Min torque limit MinT
Function
:
The restriction starts when the measured torque passes TStart. After this the step is
stopped immediately if the measured torque falls below the level MinT. The restriction is
only active until the control function of the step has shut off, since the torque normally drops
when the spindle is stopped.
Note that the restriction is not active during the torque spike elimination phase in the
beginning of the step. The search for TStart starts then the torque spike elimination is
finished.
