oP.27, Bit 8
If the function is activated, oP.10 is considered as reference value for the modes "constant ascent" and "ogive
run" for forward direction and oP.11 for reverse direction. The specified reference value applies furthermore in
the mode for constant time.
Limitations:
The scaling factor of the ramp time is very comprehensive. Therefore all involved parameters are accepted
neither for analog setting nor as process data.
Since this is not valid for oP.10 and oP.11, there are the following restrictions for compatibility reasons:
- Analog setting of oP.10
- oP.10 or oP.11 as process write date
The calculation of the ramp times is not executed with these settings, even if it is adjusted in oP.27. The pre-
vious adjustment remains. The calculation is executed only after power on, at set copying and direct writing of
the parameters.
- POSI function with Pn.63
The variable reference value must be deactivated for a correct calculation of the constant run time!
7.4.8.2 Ramp with constant ascent
This mode is the KEB factory setting. The acceleration / deceleration values are defined with parameters oP.28
to oP.31.
The jerk (i.e. the permissible acceleration / deceleration change) is defined with parameters oP.32...oP.35 and
oP.70... oP.73.
