￭ Connection examples of two-wire and three-wire sensors to analog
input (AI2)
Note: The maximum capability of the auxiliary voltage output (24 V DC [250 mA]) must not
be exceeded.
An example of a two-wire sensor/transmitter supplied by the drive auxiliary voltage output
is shown below. Set the input signal to 4...20 mA, not 0...20 mA.

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.
