2-12 Analog Inputs
Configuration #4:
• [Minimum Speed] = 0 Hz.
• [Maximum Speed] = 60 Hz.
• [Analog In 1 Lo] = 100%
• [Analog In 1 Hi] = 0%
This configuration is used to invert the operation of the input signal. Here,
maximum input (100% of 10 Volts = 10 Volts) represents [Minimum Speed]
of 0 Hz and minimum input (0% of 10 Volts = 0 Volts) represents
[Maximum Speed] of 60 Hz.
Configuration #5:
• [Minimum Speed] = 0 Hz.
• [Maximum Speed] = 60 Hz.
• [Analog In 1 Lo] = 0%
• [Analog In 1 Hi] = 50%
This configuration is used when the input signal is 0-5 volts. Here,
minimum input (0% of 10 Volts = 0 Volts) represents [Minimum Speed] of
0 Hz and maximum input (50% of 10 Volts = 5 Volts) represents [Maximum
Speed] of 60 Hz. This allows full scale operation from a 0-5 volt source.
