"0 .. Max" control characteristic
Alternatively, the "Min .. Max" control characteristic can
be switched to "0 .. Max" by a change in parameter.
• In the "0 .. Max" control characteristic, in addition to
the DI1 (X13: 2) start command, a setpoint signal of
> 1% (0.1 V) is required for starting the compressor.
The setpoint signal presets the frequency to a value
between 0 Hz and the maximum frequency. If the
signal is > 1% but lower than the minimum frequency
of the compressor, the compressor will run at the
minimum frequency.
Graphical explanation of the "0 .. Max" control charac-
teristic, see figure 12, page 54.
