18.3

Additional drive element

18.3.1

Rated torque loss is exceeded

18.3.2

Min. ratio (K) is higher than max. ratio (K)

Note!

The constant torque loss at the output end of the additional drive component is xxx. Thus the rated torque

loss of yyy is exceeded.

Cause

Effects

Possible remedies

The general ratio is characterised by

the "permissible torque". The effi-

ciency in this operating point defines

the max. constant loss of yyy. Accord-

ing to this definition, the constant

torque loss exceeds the limit value.

Constant torque loss ( 345)

The entered values are not consist-

ent. The calculation leads to wrong

results.

Correct the entries.

Stop!

The ratio range of the additional drive element has not been entered correctly.

The minimum value is greater than the maximum value.

With these values, dimensioning is not possible.

Cause

Effects

Possible remedies

The entered min. ratio (i

min,K

) of the

"additional drive element" is higher

than the entered max. ratio (i

max,K

).

Drive dimensioning cannot be car-

ried out.

Exchange the entered values for i

m-

in,K

and i

max,K

.
