Multi-Speed Select - Hitachi L200 Series Instruction Manual

Multi-Speed Select

The inverter can store up to 16 different target
frequencies (speeds) that the motor output uses for
steady-state run condition. These speeds are acces-
sible through programming four of the intelligent
terminals as binary-encoded inputs CF1 to CF4 per
the table to the right. These can be any of the six
inputs, and in any order. You can use fewer inputs
if you need eight or fewer 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 example with eight speeds in the figure below
shows how input switches configured for CF1–CF3
functions can change the motor speed in real time.
