Travel to fixed stop

The function can be used to move the motor to a fixed stop at a specified torque without a
fault being signaled. The specified torque is built up and remains applied after the motor
reaches the fixed stop.
The desired torque derating is brought about by scaling the upper torque limit and the lower
torque limit.
Function behavior in speed (S) control mode
When SINAMICS V90 PN is working in the speed (S) control mode, the "travel to fixed stop"
function can be used in all the telegrams except the standard telegram 1, because the
function through telegram is part of STW2 and ZSW2 and they are not included in standard
telegram 1.
The function can be enabled by the PROFINET control word STW2.8 and the drive status
can be indicated by the status word ZSW2.8:

When PROFINET telegrams 2, 3, and 5 are used, no torque reduction is transferred. When
the "Travel to fixed stop" function is activated, the motor ramps up to the torque limits.
When PROFINET telegrams 102 and 105 are used, the torque can be reduced by the
control word MOMRED.
