SK CU4-IOE / SK TU4-IOE- …
Connection of a KTY-84 to either of the two analog inputs of the relevant option is possible. In the following
examples, analog input 2 of the particular optional module is used.

Parameter settings (Analog input 2)
The following parameters must be set for the function of the KTY84-130.
1. The motor data P201-P207 must be set according to the rating plate.
2. The motor stator resistance P208 is determined at 20°C with P220 = 1.
3. Function analog input 2, P400 [-04] = 30 (Motor temperature)
4. The mode for analog input 2, P401 [-02] = 1 (negative temperatures are also measured)
5. Adjustment of analog input 2: P402 [-02] = 1.54V and P403 [-02] = 2.64V (with R
V
= 2.7 kOhm)
6. Adjust time constants: P161 [-02] = 400ms (Filter time constant is at a maximum)
Parameter (P161) is a module parameter. This cannot be set on the frequency inverter, but rather directly on the I/O-module.
Communication is carried out e.g. via the direct connection of a ParameterBox to the RS232 interface of the module or by the
connection of the frequency inverter via the system bus. (Parameter (P1101) object selection

7. Motor temperature control (display): P739 [-03]
NOTE
To determine the stator resistance of the motor, the temperature range 15 … 25°C should not
be exceeded.
Excess temperature of the motor is also monitored and at 155°C (switching threshold for the
thermistor) causes the drive unit to shut down with error message E002.
