Configuration #5:
•
[Anlg In Config], bit 0 = “0” (Voltage)
•
[Speed Ref A Sel] = “Analog In 1”
•
[Speed Ref A Hi] = 60 Hz
•
[Speed Ref A Lo] = 0 Hz
•
[Analog In 1 Hi] = 5V
•
[Analog In 1 Lo] = 0V
This configuration is used when the input signal is 0-5 volts. Here, minimum
input (0 Volts) represents 0 Hz and maximum input (5 Volts) represents 60 Hz.
This allows full scale operation from a 0-5 volt source.
