at least 800mA (input) Voltage supply for the FI control unit.
This is essential for the function of
the frequency inverter.

24V ± 25%
max. 200mA (output)
Supply voltage provided by the
frequency inverter for connection to
the digital inputs or the supply of a
10-30V encoder.
The 24V control voltage is
generated by the FI, however it can
also be supplied via the terminals
X12:44/40. Supply via terminal
X5:44 is not possible.
