Motor components
3.2 Cooling
Two temperature sensor types are integrated:
Table 3- 1
Type
Resistance when cold
(20° C)
Resistance when hot
(100° C)
Connection
Response temperature Prewarning < 150° C
High short-term overload conditions require additional protective measures as a result of the
thermal coupling time of the temperature sensor.

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
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.
