15 CREEP SPEED = Minimum Speed. This Parameter sets the minimum voltage
applied to the motor at the start of travel.
16 SEAT MICRO DELAY = Delay time after Seat Microswitch has opened.
17 HYDRO TIME = Operating time for Steering Contactor after controller has oper-
ated. This Parameter is configured in the SET OPTION Menu.
18 BACKING TIME = Operation time of the BACKING Function.
19 BACKING SPEED = Drive Motor Speed during the BACKING function. The chart
on Page 23 shows the different values to which the parameters may be adjusted.
5.3 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).
