Driver Proportional Gain / Driver Integral Gain
The 1356 /1356P uses a Proportional/Integral (PI) controller to minimize the
error between the command and the actual output in Constant Current mode
and Constant Voltage mode. The PI controller works with two parameters,
proportional gain (Kp) and integral gain (Ki). Normally, the default settings
of these gains are sufficient to control the load. However, there may be times
when they need to be adjusted to increase or decrease the responsiveness of
the 1356 /1356P.
If the 1356 /1356P over-reacts to changes in battery or load, lower these
gains. If it is too slow to react, increase them. If the gains are set too high, the
output may oscillate. Normally, the Proportional and Integral gains are increased
or decreased together. It is not recommended to have one gain very high while
the other is very low.
