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.
￭

Safe torque off (X4)

For the drive to start, both connections (+24 V DC to IN1 and +24 V DC to IN2) must
be closed. By default, the terminal block has jumpers to close the circuit.
Remove the jumpers before connecting an external Safe torque off circuitry to the
drive. See also chapter
