Allen-Bradley PowerFlex User Manual

Analog Inputs 2-11
Configuration #3:
• [Speed Ref A Sel] = “Ana In 1”
• [Minimum Speed] = 0 Hz.
• [Maximum Speed] = 60 Hz.
• [Analog In 1 Lo] = 20%
• [Analog In 1 Hi] = 100%
This configuration is referred to as offset. In this case, a 2-10 volt input
signal provides 0-60 Hz output, providing a 2 volt offset in the speed
command.
