One, two or three Pt100, Pt1000 or PTC sensors; or one KTY84 sensor 1
Set the input type to voltage with the appropriate switch or jumper on the control unit. Make the
corresponding setting in the control program in parameter group 12 Standard AI. 2
Select the excitation mode in parameter group 13 Standard AO. 3
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.
WARNING!
Make sure that the excitation current does not exceed the maximum permitted
current of the Pt100/Pt1000 sensor.

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 a high-quality shielded twisted-pair cable for the wiring, fro exmple, Belden 9842.
The nominal impedance of the cable should be 100…165 ohm. You can use one pair
for the data wiring and another pair or a wire for the grounding. Avoid unnecessary
loops and parallel runs near power cables.
The following diagram shows the wiring between control units.
