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.

gradient).
**=
The values in the table indicate how much the brakings (release, inversion,
deceleration) are reduced while H&S function is active.
***=
The values in the table indicate how much the acceleration is reduced while H&S
function is active.
****= Is a percentage of the field current which is subtracted to the value defined by
the parameters MAX SPEED FORW and MAX SPEED BACK.
*****= Indicates the percentage of the armature current (while the machine is at con-
stant maximum speed) that is subtracted to the field current.
