Example # 2: Input a voltage from a third-party sensor:
Calculate the Analog Input Scale Factor using the formula below.
Analog Input Scale Factor = 100 ×
F ÷ S
• If the sensor is connected to Analog Input 1, then enter the result into parameters 43
and 44.
If the sensor 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 sensor is connected to Analog Input 1, then the value of F is determined by
parameter 41, as shown in Table 2.
If the sensor is connected to Analog Input 2, then the value of F is determined by
parameter 42, as shown in Table 3.
S = Sensor output scale factor (volts-per-inch).

Note: If parameter 2 (end-of-travel mode) is set to 1, then F = 5. If parameter 2 is not set
to 1, then input 2 is off.
