L100 Inverter

4–7

Multi-Speed Select

The inverter provides storage parameters for up to 16 different target frequencies (speeds) that the motor output uses for steady-state run condition. These speeds are accessible through programming four of the intelligent terminals as binary-encoded inputs CF1 to CF4 per the table below. These can be any of the five inputs, and in any order. You can use fewer inputs if you need eight or less speeds.

Note: When choosing a subset of speeds to use, always start at the top of the table, and with the least-significant bit: CF1, CF2, etc.

The figure below shows how input switches config- ured with CF1 functions can change the motor speed in real time.
