8.2 Sensors
8.2.1 Connection temperature sensor
All primary parts - except frame size MCP015 - are equipped with a PTC tem‐
perature sensor KTY84-130. The temperature sensor is fixed within the motor
winding and serves for winding temperature measuring. The temperature
sensor itself offers no safe protection of the winding from thermal overload.
The thermal monitoring of the motor must additionally be done via a working
temperature modell in the controller.
Heed the right polarity of the connection wires when connecting the
KTY84-130 . The wire designation can be found under Fig. 8-1 .
For additional information on the temperature sensor, please refer to chapter
9.10 "Motor temperature monitoring" on page 107 .
● Temperature sensor KTY84-130 is a component that might
by damaged by ESD! For this reason, the wires of the sen‐
sor are protected by a protective foil at the connection cable.
Before connecting the sensor, take measures regarding
ESD protection.( ESD = electrostatic discharge).
● The used temperature sensors are double or reinforced in‐
sulated according to DIN EN 50178, so separation exists ac‐
cording to DIN EN 61800-5-1.
8.2.2 Connection Hall unit
Motors with Hall unit have an additional cable to connect the sensor. This ca‐
ble is beside the connection cable for the power. After motor installation, the
cable of the Hall unit can be shortened to the required length and be assem‐
bled with a D-sub connector, 9-pole (pin), for example. Also refer to Chap.
