Pressing the right arrow key accesses the next (third) segment
ramp rate display. The segment #3 ramp rate is set to a value of
0.05 A/sec.
Pressing the right arrow key accesses the segment #3 current
range display.
NOTE
If there is more than one segment, the upper bound of the last
segment is always the Current Limit
18
and it will be displayed as
“±Limit” as shown below and cannot be edited.
Now, when current is in the range of 0 to ±55 A, ramping will be
controlled at ±0.2 A/sec. When current is in the range of ±55 to
±58 A, ramping will be controlled at ±0.1 A/sec and when current
is greater than ±58 A (up to the limit of 60 A), ramping will be
controlled at ±0.05 A/sec.
If ramp rate of a ramp segment is being edited while the Model
430 is ramping and the system current/field transitions from the
currently edited segment to the next before the adjustment has
been committed with the
ENTER
key, the adjusted value
will be
discarded
. The display will update to show the new segment
ramp rate, and the fine adjust knob will apply to the new segment
(assuming the
ENTER
key is pressed before the segment has
completed).
If at some later time it is desired to set the Current Limit to a
value less than 58 A, only the first two ramp segments would
remain active since the new “limit” falls within the range of
segment #2. The display for segment 2 range would then appear
as follows
19
.
18. Refer to page 88.
19. If the Current Limit were to be set below 55 A, only segment #1 would be active, and would
display the upper bound of “±Limit”.
