1 RevisionNew temperature sensor /PK
Revision – Synchronous Servomotors6
1.5 New temperature sensor /PKThe temperature sensor /PK replaces the previous temperature sensor /KY.
INFORMATIONMake sure the used inverter has the relevant evaluation electronics for the PK(PT1000) temperature sensor.
1.5.1 Type designation/PK
1.5.2 DescriptionThermal motor protection in combination with the corresponding evaluation electronicsprevents the motor from overheating and consequently from being damaged. A tem-perature sensor provides only indirect protection as only one sensor value is determ-ined.The /PK design consists of a platinum sensor PT1000 installed in one of the three mo-tor windings. Unlike the /KY semiconductor sensor, the platinum sensor has an almostlinear characteristic curve and is more accurate. The frequency inverter can take onthe function of motor protection via the /PK, when it is used in combination with a fre-quency inverter containing the thermal motor model.

Revision – Synchronous Servomotors 7
1.5.3 Technical dataThe PT1000 temperature sensor continuously detects the motor temperature.
PT1000Connection red – black
Total resistance at 20 – 25 °C 1050 Ω < R < 1150 Ω
Test current < 3 mA
INFORMATIONThe temperature sensor is unipolar which means that interchanging the incomingcables does not change the measurement result.

1RevisionBrake controls with functional control input
Revision – Synchronous Servomotors 9
1.7 Brake controls with functional control inputIn addition to the voltage supply, the optional brake controls of the BMK., BMKB. andBMV. series offer a control input for a DC 24 V signal with which the brakes can beswitched via a PLC.It is a purely functional input that is not "functionally safe" with respect to safety tech-nology.Due to their operating principle, fault statuses may occur with these devices that leadto unintentional ongoing brake release, even if the control voltage has been switchedoff.
WARNINGUnintentional ongoing brake release due to unrecognized malfunction of the brakecontrol.Severe or fatal injuries, e.g. due to falling hoist or extended coasting.• Always disconnect all poles of the supply and control voltage for hoists and hoist-
like applications.• Ensure that a malfunction of the control input can be detected through additional,
suitable diagnostic measures e.g. by monitoring the braking current to meet highsafety and reliability requirements.
• Use the BST.. brake control for functional safety applications.• If you have any questions regarding the handling of the control input, contact
SEW‑EURODRIVE.
