Voltage supply for the FI control unit. Is
essential for the function of the
frequency inverter.
Supply voltage provided by the
frequency inverter for connection to the
digital inputs or for 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 (Size 8 and
above: X15:44/40). Supply via terminal
X5:44 is not possible.
