VI 24V supply
voltage input
18…30V
at least 800mA (input)
Voltage supply for the FI control unit. Is
essential for the function of the
frequency inverter.
Size 5 and above
VO 24V supply
voltage output
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 alternatively be
supplied via the terminals X12:44/40
(size 8 and above: X15:44/40). Supply
via terminal X5:44 is not possible.
