Connection Of The Cu310-2 And The Cua31/Cua32 Adapters - Siemens SINAMICS S120 Function Manual

Setting the temperature sensor
The temperature sensor type is set using p0601[0...n]. When connecting a temperature sensor
to terminal X41 of a chassis unit, you must specify to which power unit the temperature sensor
is to be connected when power units are connected in parallel. The desired power unit is
connected via p0602.
Note
Bimetallic NC contact is only possible for booksize formats
Temperature sensing using a bimetallic NC contact is only possible with Motor Modules in the
booksize format.
Note
PT100 is only possible for the chassis format
Temperature sensing using a PT100 is only possible with Motor Modules in the chassis format.
If r0192.15 = 1 is displayed, then the PT 100 temperature sensor type can be selected with
p0601[0...n] = 5.
A motor temperature offset can be set using p0624 [0...n].
Power Module chassis
A Power Module in the chassis format has one temperature channel and can evaluate PTC,
KTY84, PT1000 and PT100 temperature sensors (r0192.15 = 1).

Connection of the CU310-2 and the CUA31/CUA32 adapters

The Control Unit Adapter CUA31 and CUA32 have one temperature channel. The terminal strip
in the CUA31 has an interface for a motor temperature sensor. The temperature sensor can be
alternatively connected at the CUA32 via the encoder interface.
The Control Unit CU310-2 DP/PN has two independent temperature channels. The motor
temperature sensors can be connected via two interfaces. One of the channels is in the
encoder interface, the second channel is on the terminal strip. PTC or KTY84 temperature
sensors can be connected and evaluated.
