The Gen4 also looks at a number of internal temperature measurements and estimates. These
can also influence the thermal cutback operation, depending on installation and operating duty
cycle
Circuit configuration
Once motor size is determined the application circuit configuration can be defined. A basic single
traction configuration (Figure 13) is provided as a starting point for new designs. Given the
flexibility of the I/O it is possible to configure a wide range of systems. Refer to ‘Signal
connections’ on page 3-14 to see what each I/O signal is capable of doing as you design your
system. For pump applications a basic single pump system is shown in Figure 14.
