Data cable RS485
Baud rate
9600…38400Baud
Termination resistor
R=120Ω
BUS connection parallel to RS485 on
RJ12 plug
NOTE: The termination resistance of
DIP switch 1 (see RJ12/RJ45) can also
be used for terminal 73/74.

With inductive loads:
provide protection via free-
wheeling diode.
For evaluation in a control system. The
scope of functions corresponds to that of
the relay (P434).

VI 24V supply
voltage input
18…30V
min. 800 mA (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 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 X7:44 is not possible.
