Ai1 Or Ai2 As A Pt100, Pt1000, Ptc Or Kty84 Sensor Input; Diil Input - ABB ACS880-107 Series Hardware Manual

50 Control units of the drive
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.

AI1 or AI2 as a Pt100, Pt1000, PTC or KTY84 sensor input

Sensors for motor temperature measurement can be connected between an analog input
and output, an example connection is shown below. (Alternatively, you can connect the
KTY to an FIO-11 or FAIO-01 analog I/O extension module or FEN-xx encoder interface
module.) At the sensor end of the cable, leave the shields unconnected or ground them
indirectly via a high-frequency capacitor with a few nanofarads, for example 3.3 nF / 630 V.
The shield can also be grounded directly at both ends if they are in the same ground line
with no significant voltage drop between the end points.

T
1 One, two or three Pt100, Pt1000 or PTC sensors; or one KTY84 sensor
2 Set the input type to voltage with J1 for analog input AI1 or with J2 for analog input AI2. Set the appropriate
analog input unit to V (volt) in parameter group 12 Standard AI.
3 Select the excitation mode in parameter group 13 Standard AO.
1)
Set the input type to voltage with the appropriate switch or jumper on the inverter control
unit. Make the corresponding setting in the inverter unit control program in parameter group
12 Standard AI.
2)
Select the excitation mode in parameter group 13 Standard AO of inverter unit control
program.

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.
