If the motor temperature sensor has a reinforced insulation vs. the motor windings, you can
connect it directly to the drive IO interface. This section shows the connection. If the sensor
has no reinforced insulation, you must use another type of connection to fulfill the safety
requirements. See Implementing a motor temperature sensor connection (page 48).
You can connect temperature measurement sensors (one, two or three Pt100 sensors; one,
two or three Pt1000 sensors; or one Ni1000, KTY83 or KTY84) between an analog input
and output as shown below. Leave the sensor end of the cable shield unconnected.
See the firmware manual for information on the related Motor thermal protection function.
1…3 × (Pt100 or Pt1000) or 1 × (Ni1000 or KTY83 or KTY84)1
Analog input. Set the analog input type to V (volt) in parameter group 12 Standard AI. Define the temper-
ature sensor type, signal source, etc. with parameters 35.11. to 35.24. Set the analog input type to V
(volt) in parameter group 12 Standard AI.

Analog output. Select the Excitation mode for the analog output in parameter group 13 Standard AO.

Auxiliary voltage connection
The drive has an auxiliary 24 V DC (±10%) auxiliary power supply terminals both on the
base unit and on the RIIO-01 module. You can use it:
• to supply auxiliary power from the drive to external control circuits or option modules
• to supply external auxiliary power to the drive in order to keep the control and cooling
in operation also during a drive input power break.
See the technical data for the specifications for the auxiliary power supply terminals
(input/output).
If you want to supply power to external control circuits or option modules:
1. Connect the load either to the auxiliary power output on the base unit, or on RIIO-01
module (+24V and DGND terminals).
2. Make sure that you do not exceed the load capacity of the output, or the sum load
capacity of both outputs.
If you want to connect an external auxiliary power supply to the drive:
1.
Install a BAPO-01 power extension module to the drive. See Installing options (page 66).
2. Connect an external power supply to the +24V and DGND terminals of the base unit.
For more information on the BAPO-01 module, see BAPO-01 auxiliary power extension
module (page 165).
