5 Fieldbus (FBProcessDataIN2)
This signal will adjust the maximum motor current between 0 and Motor current limit
(ID107).
400 SCALING OF DC-BRAKING CURRENT 6 (2.2.6.2)
Use this parameter to select the signal to adjust the DC-braking current.
See parameter ID399 for the selections.
DC-braking current can be reduced with the free analogue input signal between zero current
and the current set with parameter ID507.

401 SCALING OF ACCELERATION AND DECELERATION TIMES 6 (2.2.6.3)
Use this parameter to select the signal to adjust the acceleration and deceleration times.
See parameter ID399.
Acceleration and deceleration times can be reduced with the free analogue input signal
according to the following formulas:
Reduced time = set acc./deceler. time (parameters ID103, ID104; ID502, ID503) divided by the
factor R from Fig. 62.
