CU310-2/CUA31/CUA32

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.
CUA32
Setting the temperature measurement and the temperature channels:
● p0600[0...n] = 10 sets the temperature sensing via BICO interconnection.
● p4600[0...n] sets the sensor type for temperature channel 1 (encoder interface).
● p4601[0...n] sets the sensor type for temperature channel 2 (terminal strip).
CU310-2 DP/PN (AC Drive)
Setting the temperature sensing and the temperature channels:
● p0600[0...n] = 10 sets the temperature sensing via BICO interconnection.
● p4600[0...n] sets the sensor type for temperature channel 1 (encoder interface).
● p4601[0...n] sets the sensor type for temperature channel 2 (terminal strip).
