5.4 TABLE OF ADJUSTMENTS
The following Table shows the different values that the SEM2 Parameters may be
adjusted to. A suitable acceleration performance assumes: FIELD CURR. NOM is set
to level 5, and MAX SPEED (Fwd or Rev) is set to level 9.

*=
If the current inclines to raise, then also the braking time raises in order to obtain
a smooth
braking action. Therefore, the duration of the braking depends on
the type of motor and the operating conditions (laden, unladen, on plane, on
gradient).
**=
Is a percentage of the field current which is subtracted to the value defined by
the parameters MAX SPEED FORW and MAX SPEED BACK.
