4.7.11. Ramps
4.7.11.1. Ramp-min function
In the DRIVECOM profile, there are each two ramps for the nominal
speed, one absolute and one relative ramp.
For the absolute ramp, the slope of the ramp is determined by the
parameter "delta_speed / "delta_time". Absolute ramps in the
DRIVECOM profile are "speed acceleration" and "speed deceleration".
For the relative ramp, the slope of the ramp is determined by the
parameter "delta_time", referred to the speed reference (L-C011). This
corresponds to the Lenze ramp function of L-C012 and L-C013.
Relative ramps in the DRIVECOM profile are acceleration and
deceleration time.
The ramp-min function determines the slower ramp and transmits it to
the controller. The absolute ramps are deactivated in the factory
setting.
4.7.11.2. Speed acceleration (6048
hex
)
The parameter "speed acceleration" corresponds to the absolute
speed ramp of the acceleration. The slope is entered indirectly via
the parameters "delta_speed" / "delta_time". The parameter is
mapped via the ramp-min function to the Lenze acceleration ramp
(L-C012). If the parameter "delta_time" = 0, the ramp is switched
off.
