Figure 4 illustrates the command voltage input to current output
relationship for periods of time less than 2.7 seconds.
Figure 4. Input Voltage to Output Current Relationship for Periods
of Time Less Than 2.7 Seconds
Figure 5 shows the command voltage input to current output relationship
for periods of time greater than 2.7 seconds. The maximum current output
corresponds to the continuous current limit, I
cont
. Therefore, command
voltages that would result in a higher current output than I
cont
when the gain
is applied instead result in a current output of I
cont
.
