Getting Started 1-3

Figure 1.2 TPO timing diagram

The TPO duty cycle (Y) must be considerable shorter in time than

the system dead time. For additional information, Refer to Autotune

a Loop on page 5-2.

The following memory map shows you how the SLC processor’s

output and input image tables are defined for the module. See Table

9.A: BTM201.rss N7 Data Table on page 9-2.

TPO bit

Off

CV% = (40%)

X = on time (2.0 sec)

Y = TPO period (5.00 sec)
