Two temperature sensor types are integrated:
Table 3- 1 Features and technical data
Type KTY 84-130 Pt1000
Temperature sensors KTY 84 are
ESD components. When delivered,
they are short-circuited with a termi-
nal.
Pt1000 temperature sensors are not
ESD components.
Resistance when cold
(20° C)
Approx. 580 Ω Approx. 1090 Ω
Resistance when hot
(100° C)
Approx. 1000 Ω Approx. 1390 Ω
Connection Via signal cable Via signal cable
Response temperature Prewarning < 150° C
Alarm/trip at max. 170° C ±5° C
Prewarning < 150° C
Alarm/trip at max. 170° C ±5° C
High short-term overload conditions require additional protective measures as a result of the
thermal coupling time of the temperature sensor.
3.2 Cooling
Note
The manufacturer of the motor spindle is responsible for the design and construction of the
cooling.
Information about the materials and components in the cooling circuit is contained in the
Configuration Manual.
Please observe the spindle manufacturer's project requirements.
Equipotential bonding
WARNING
Danger to life by incorrectly routing cooling water pipes
If electrically conductive cooling water pipes come into contact with live parts, this can
cause an electric shock leading to death or severe injury.
• Ensure adequate insulation.
•
Securely fasten the pipes.
● Provide all components in the cooling system (motor, heat exchanger, piping system,
pump, pressure equalization tank, etc.) with equipotential bonding.
● Implement the equipotential bonding using a copper rail or finely stranded copper cable
with the appropriate conductor cross-sections.
