Drive control and features

The figure below shows typical KTY84 sensor resistance values as a function of the
motor operating temperature.
It is possible to adjust the motor temperature supervision limits and select how the
drive reacts when overtemperature is detected.
WARNING!
As the thermistor input on the JCU Control Unit is not insulated
according to IEC 60664, the connection of the motor temperature sensor requires
double or reinforced insulation between motor live parts and the sensor. If the
assembly does not fulfil the requirement,
- the I/O board terminals must be protected against contact and must not be
connected to other equipment
or
- the temperature sensor must be isolated from the I/O terminals.
The figure below shows a motor temperature measurement when thermistor input
TH is used.
