An example of a three-wire sensor/transmitter supplied by the drive auxiliary voltage
output is shown below.The sensor is supplied through its current output and the drive
feeds the supply voltage (+24 V DC). Thus the output signal must be 4…20 mA, not
0…20 mA.

DI5 as frequency input
For setting the parameters for the digital frequency input, see the firmware manual.
￭
DI6 as PTC input
If DI6 is used as a PTC input, see firmware manual for how to set parameters
accordingly.
Note: If DI6 is used as a PTC input, the wiring and the PTC sensor need to be double
isolated. Otherwise the CMOD-02 I/O extension module must be used.

Sensors for motor temperature measurement can be connected between an analog
input and output. An example connection is shown below. Leave the other end of the
shield unconnected or ground it indirectly via a few nanofarads high-frequency
capacitor, 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.
