CU310-2 DP / CU310-2 PN
The Control Unit 310-2 has an integrated SMC30 encoder interface. This encoder interface
is accessed via the 15-pin Sub-D-contact X23 and is evaluated as temperature channel 1.
There are three options available to evaluate the temperature:
1. Temperature channel 1 via the SMC30 encoder interface X23.
2. Temperature channel 1 via terminal X120, for example, if an encoder is being used.
3. Two temperature channels via X23 and X120. Encoder interface X23 is assigned to
The following parameter settings must be made:
For 1. One temperature channel 1 via encoder interface X23:
● p0600[0..n] = 1: Selects the encoder (1, 2 or 3), which is assigned to encoder interface
● p0601[0..n] = 1 or 2: Selection of the temperature sensor type, n = motor data set
● r0035: Display of the temperature value.
For 2. One temperature channel 1 via terminal X120:
● p0600[0..n] = 11: Activation from temperature channel 1 via terminal X120
● p0601[0..n] = 1 or 2: Selection of the temperature sensor type, n = motor data set
● r0035: Display of the temperature value.
For 3. Two temperature channels via X23 and X120:
● p0600[0..n] = 1: Selects the encoder (1, 2 or 3), which is assigned to encoder interface
● p0601[0..n] = 10: Evaluation via several temperature channels
● p4600[0..n]: Selection of the temperature sensor type from temperature channel 1, n =
● p4601[0..n]: Selection of the temperature sensor type from temperature channel 2, n =
● r4620[0...3]: Reading the temperature values.
● r0035: Display of the higher temperature value of temperature channels 1 and 2.
CUA31
The parameterization of the temperature evaluation via terminal X210 can be performed
using the STARTER screen (signals and monitoring \ motor temperature). "Temperature
sensor via Motor Module (11)" should be selected in the "Temperature sensor selection"
field. The temperature of the sensor is displayed in r0035.
