WARNING!
As the inputs pictured above are not insulated according to IEC/EN 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.
DIIL input
The DIIL input is used for the connection of safety circuits. The input is parametrized to stop
the unit when the input signal is lost.
Note:
This input is NOT SIL or Pl certified.
The XD2D connector
The XD2D connector provides an RS-485 connection that can be used for
•
basic master/follower communication with one master drive and multiple followers,
•
fieldbus control through the embedded fieldbus interface (EFB), or
•
drive-to-drive (D2D) communication implemented by application programming.
See the firmware manual of the drive for the related parameter settings.
Enable bus termination on the units at the ends of the drive-to-drive link. Disable bus
termination on the intermediate units.
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 parallel runs near power cables such as motor cables.
The following diagram shows the wiring between control units.

Safe torque off (XSTO, XSTO OUT)
See chapter
The Safe torque off function (page 167)
Note:
The XSTO input only acts as a true Safe torque off input on the inverter control unit.
De-energizing the IN1 and/or IN2 terminals of other units (supply, DC/DC converter, or brake
unit) will stop the unit but not constitute a true safety function.
