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.
