Notes
• The drive controller and encoder codes are a part of the type designation of the motor (see the "Type
designation" chapter).
11.6.5 Temperature sensor
In this chapter, you can find technical data for the temperature sensors that are installed in STOBER syn-
chronous servo motors for implementing thermal winding protection. To prevent damage to the motor, al-
ways monitor the temperature sensor with appropriate devices that will turn off the motor if the maximum
permitted winding temperature is exceeded.
Some encoders feature integrated temperature monitoring, the warning and switch-off thresholds of which
may overlap with the corresponding values set for the temperature sensor in the drive controller. In some
cases, this may result in an instance where an encoder with internal temperature monitoring forces the mo-
tor to shut down, even before the motor has reached its nominal data.
You can find information about the electrical connection of the temperature sensor in the "Connection
method" chapter.
