Example # 3: Input an end-of-travel potentiometer voltage:
Calculate the Analog Input Scale Factor using the formula below.
Analog Input Scale Factor = 100
×
F
÷
P
•
If the potentiometer is connected to Analog Input 1, then enter the result into
parameters 43 and 44.
If the potentiometer is connected to Analog Input 2, then enter the result into
parameters 45 and 46.
Refer to page 17 for more information about setting these parameters.
F = Full-scale input range (volts).
•
If the potentiometer is connected to Analog Input 1, then the value of F is determined
by parameter 41, as shown in Table 2 on page 53.
If the potentiometer is connected to Analog Input 2, then the value of F is determined
by parameter 42, as shown in Table 3 on page 53.
P = Potentiometer scale factor (volts-per-inch).
•
If the potentiometer is part of an AccuWeb actuator assembly and is connected to the
controller’s +5V REF and SIG GND terminals, then refer to Table 4 for the specific
potentiometer scale factor value.
