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

Monitoring and protective functions
9.5 Thermal motor protection
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 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.

Setting the temperature measurement and the temperature channels:
● p0600[0...n] = 11 sets the temperature channel via CU terminals.
● p0601[0...n] = 0/1/2/3/5 sets the temperature sensor type and the response.
