8. Operating modes
196
Festo P.BE-CMMP-CO-SW-EN 0708NH
The parameters ramp steepness
torque_slope
and ramp shape
torque_profile_type
must
be specified for the ramp generator.
If bit 8
Halt
is set in the
controlword
, the ramp generator falls down to zero. It rises
correspondingly again to the nominal torque
target_torque
when bit 8 is deleted again.
In both cases, the ramp generator takes into account the ramp steepness
torque_slope
and the ramp shape
torque_profile_type
.
All definitions within this document refer to rotatable motors. If linear motors have to be
used, all "torque" objects must refer to a "force" instead. For simplicity, the objects do
not appear twice and their names should not be changed.
The operating modes positioning mode (profile position mode) and velocity controller
(profile velocity mode) need the torque controller to work. That is why it is always
necessary to set its parameters.
