VI 24V supply
voltage input
18…30V
min. 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. 200 mA (output)
short circuit resistant
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.
