Functional Description Special Functions
The diameter signal is evaluated within the range of 0% to 100%. Values < 0% are set
to 0%, values > 100% are limited to 100%.
The diameter signal of 0% corresponds to the minimum diameter of the reel bale
(d
min
). The output speed of the ramp generator is not changed in this case. A diameter
signal of 100% corresponds to the maximum diameter of the reel bale (d
max
). In order
to be able to calculate the speed change the program requires the ratio of minimum to
maximum diameter (d
min
/d
max
).
The ratio of minimum to maximum diameter (d
min
/d
max
) 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 frequency of the ramp generator is determined as follows:
fn_Ramp: Output freqency/speed of ramp generator
fn_presetting: Corrected output frequency/speed
DS: Diameter signal 0 - 100% (0 to 1)
oP.49: (d
min
/d
max
)
The rate of change of the diameter signal can be limited by a ramp generator. By way
of oP.46 the time can be preset within the range of 0.0...20 s, which is required for a
signal difference of 0...100%.
