Insert torque [Torque] In order to reach the mechanical end position accurately and
stop free of play, the torque can be reduced to the insert
torque when the nominal position is reached (torque switch
ing). The torque switching can be set for all positioning sets
with absolute position specification.
Operation without torque switching
If a precise mechanical end position is not required, you can
shorten the pulse time (travel time) by setting the insert
torques in the positioning set table to zero. No torque switch
ing then takes place. When controlling the end positions
(Pos0, Pos 1), the drive does not move to the stop, but posi
tions itself with rated motor torque in the nominal position
and remains there controlled. No torque switching then takes
place. Advantage: shorter travel time and therefore higher
pulse rate.
Operation with torque switching
In operation torque switching means:
The drive positions itself at first at the set speed [Velocity]
and with the rated torque. When the nominal position is
reached, the torque will be reduced to the value set with
[Torque]. The drive moves torque−controlled at a constant,
factory−specified speed to the stop (= mechanical end posi
tion) and presses" torque−controlled against the stop. At the
next positioning command the drive positions itself again
with the rated motor torque.
