Tripping currents at short-circuit
The tripping current must also be reliably reached in the event of
short-circuit. In operation, observe that the total current of all
motors (including the starting currents) or the charging current of
all connected speed control units RA-SP remains below the
tripping current when mains voltage is applied.
With the disconnect control unit RA-DI you can achieve long cable
lengths and high total currents.
Information to EMC
For information about EMC, see the following sections of this
manual. See also the engineering notes in manual “Frequency
inverter DF5” (AWB 8230-1412G)
Loads
Consumers can be any three-phase asynchronous motor. Pole-
changing (Dahlander) three-phase motors, slipring motors and
reluctance-, induction-type synchronous or servo motors can also
be connected, provided their electrical and connection
characteristics correspond with asynchronous motors and are
approved for the application by their manufacturer.
With user-assembled motor connection plugs the length of the
screened motor supply cable with servo cable for the speed control
unit RA-SP and the motor supply cable for the motor control unit
RA-MO is limited to 25 m.
Addressing slaves
(with hand-held addressing unit PG2-105-AD2)
With the addressing unit PG2-105-AD 2 suitable for specification
2.1 you can address the slaves:
• to specification 2.0 with 31 possible stations
• to specification 2.1 with 31 or 62 possible stations.
X
Plug the M12 plug of the function modules into the socket of
the addressing unit and press button ADR.
On the display the currently set address is now shown. The factory
settings are:
• For RA-DI and RA-SP: 00 (31 possible stations)
• For RA-MO: 00A (62 possible stations)
With the arrow keys you can select a new address.

supply 400 V AC” on page 13.
