DI6 (XDI:6) as PTC sensor input
One PTC sensor can be connected to this input for motor temperature measurement as
follows. The sum of the sensor resistances must not exceed the threshold resistance of
the digital input at the motor normal operating temperature. Do not connect both ends of
the cable shield directly to ground. If a capacitor cannot be used at one end, leave that end
of the shield unconnected. See the firmware manual for the parameter settings.
DIIL input (XD24:1)
The DIIL input can used for the connection of safety circuits. By default, the input is
parametrized to stop the drive when the input signal is lost.
Drive-to-drive link (XD2D)
The drive-to-drive link is a daisy-chained RS-485 transmission line that can be used for
basic master/follower communication with one master drive and multiple followers
fieldbus control through the embedded fieldbus interface (EFB), and
drive-to-drive (D2D) communication implemented by application programming.
See the firmware manual of the drive for the related parameter settings.
Set termination activation jumper J3 next to this terminal block to the ON position on the
drives at the ends of the drive-to-drive link. On intermediate drives, set the jumper to the
OFF position.
Use shielded twisted-pair cable with a twisted pair for data and a wire or another pair for
signal ground (nominal impedance 100 to 165 ohm, for example Belden 9842) for the
wiring. For best immunity, ABB recommends high quality cable. Keep the cable as short as
possible. Avoid unnecessary loops and running the cable near power cables (such as
motor cables).
WARNING! As the inputs pictured above are not insulated according to
IEC 60664, the connection of the motor temperature sensor requires double or
reinforced insulation between motor live parts and the sensor. If the assembly
does not fulfill the requirement, the I/O board terminals must be protected against contact
and must not be connected to other equipment or the temperature sensor must be
isolated from the I/O terminals.
