AI1 and AI2 as Pt100, Pt1000, Ni1000, KTY83 and KTY84 sensor inputs
(X1)
One, two or three Pt100 sensors; one, two or three Pt1000 sensors; or one Ni1000, KTY83
or KTY84 sensor for motor temperature measurement can be connected between an
analog input and output as 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.
1...3 × (Pt100 or Pt100) or
1 × (Ni1000 or KTY83 or KTY84)

1. Set the input type to voltage with switch S1 for analog input AI1or with S2 for analog input AI2. Set the
appropriate analog input unit to V (volt) in parameter group 12 Standard AI.
2. Select the excitation mode in parameter group 13 Standard AO.
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.
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.

Note: Only 24 V DC can be used for STO. Only PNP input configuration can be used.
Connecting a control panel
With door mounting kit (option +J410), connect the control panel to the control unit as
shown in DPMP-02/03 mounting platform for control panels Installation guide
(3AUA0000136205 [English]).
Note 1: When a PC is connected to the control panel, the control panel keypad is disabled.
In this case, the control panel acts as a USB-RS485 adapter.
