Special functions
The diameter signal of 0% corresponds to the minimum diameter of the reel bale (dmin).
The output speed of the ramp generator (ru.02) is not changed in this case.
A diameter signal of 100% corresponds to the maximum diameter of the reel bale (dmax).
The ratio of minimum to maximum diameter (dmin/dmax) must be known in order to be able to calculate the
required speed change.
The ratio of minimum to maximum diameter (dmin/dmax) is preset by way of oP.49 and can be adjusted within
the range of 0,010...0,990 with a resolution of 0,001.
The corrected output speed of the ramp generator is determined as follows:
fn_Ramp
fn_Setting: = –––––––––––––––
1+DS • (1/oP.49-1)
fn_Ramp: Output frequency/speed of ramp generator
fn_presetting: Corrected output frequency/speed
DS: Diameter signal 0…100 % (0…1)
oP.49: (d
min
/d
max
)
Rate of change of the diameter signal
The rate of change of the diameter signal can be limited by a ramp generator.
Parameter oP.46 „ext. funct. acc/dec time“ defines a time within the range of 0.00...20.00 s, which is required
for a change of the diameter signal of 0...100%.
7.15.8 Analog setting of parameter values
With this function it is possible to preset parameter values analog. The AUX-function or the motor-poti function
can be adjusted as source.
Analog parameter setting source (An.53)
This parameter determines whether the analog parameter setting occurs via the motor-poti or the aux-function.

The bus address of the parameter, that is to be adjusted in analog mode, is adjusted here (see chapter 11.1).
Following parameters can be adjusted.
