Example 4: Conguring outputs to drive loads
A vehicle congured as shown in Figure 7, with Driver 3 running a pump. Here the I/O mapping
is such that the li-input on Switch 5 will drive this pump at 100% duty cycle with 0.5 s so start.
For Switch 5 to function as a switch input, the Encoder Enable parameter under 40-Vehicle
Speed must be set to O. For Driver 3 to be used as a low-side driver, 86-Driver 3/4 Actuator and
88/89-Driver 3/4/5 Actuator must be disabled, and 82-Driver 3 Disabled/Low Side must be set to 1
(Low Side).
Switch 5, like all digital signals in the I/O map, takes a value of 0% when O, and 100% when
On, so this signal already generates the specied duty cycle for Driver 3, except for the so start
requirement—which is generated by inserting the 73-Slew Limit 1 function into the signal chain. If
a duty cycle other than 100% is required, generate it by inserting one of the PWM functions (objects
57-61) into the signal chain before the slew limiter.
Both 73-Slew Limiter 1 and 82-Driver 3 have an Enable Input parameter as well as an Input parameter.
For both of these, the Input parameter species the duty cycle, and the Enable Input parameter will
force the output to 0% whenever the mapped signal is 0% (in the case of the slew limiter, by applying
the Rate Down parameter). Because the example does not specify any criteria to enable the output,
map both to Object 100, which is Always On 100%.
