2-10 Analog Inputs
Configuration #1:
• [Speed Ref A Sel] = “Analog In 1”
• [Minimum Speed] = 0 Hz
• [Maximum Speed] = 60 Hz
• [Analog In 1 Lo] = 0%
• [Analog In 1 Hi] = 100%
This is the default setting, where minimum input (0 volts) represents
[Minimum Speed] of 0 Hz and maximum input (10 volts) represents
[Maximum Speed] of 60 Hz.
Configuration #2:
• [Speed Ref A Sel] = “Analog In 1”
• [Minimum Speed] = 0 Hz
• [Maximum Speed] = 30 Hz
• [Analog In 1 Lo] = 0%
• [Analog In 1 Hi] = 100%
This is an application that only requires 30 Hz as a maximum output
frequency, but is still configured for full 10 volt input. The result is that the
resolution of the input has been doubled, providing only 3 Hz change per
input volt (Configuration #1 is 6 Hz/Volt).
