Peak Current Suppression Function

This function suppresses the peak current by automatically changing the values of the upper limit output limiter of each
channel and dividing the timing of the transistor output. The timing can be divided into two to four parts.

Since all the transistor outputs used
turn on at the same time, the peak
current becomes high.
