4.3. Ramps for quick stop / disable ramp function generator / QSP

4.3.1.

Ramp-min function

In the DRIVECOM profile, two ramps are defined for the controller
commands quick stop, disable ramp function generator and the QSP
terminal function (one absolute ramp, one relative ramp). The ramp
min function recognizes the slower ramp and transmits it to the
controller.

Absolute ramp ('speed quick stop')
The ramp flank is determined by the parameters "delta_speed" /
"delta_time". The absolute ramp is deactivated in the factory setting.

Relative ramp ('quick stop time')
The ramp slope 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.

4.3.2.

Speed quick stop (604A

hex

)

The parameter "speed quick stop" corresponds to the absolute
speed ramp of the deceleration for the control commands "quick
stop", "disable ramp function generator" or the QSP terminal
function. The slope is entered indirectly via the parameter
"delta_speed" / "delta_time". The parameter is mapped to the
ramp-min function via the Lenze quick stop ramp (L-C105). If the
parameter "delta_time"=0, the ramp is switched off.
