4.11.4 Temperature monitoring of the motor

Three different encoder types can be utilized:
m KTY84/130 (PTC with an almost linear characteristic for precise evaluation of the tem-
m Temperature switch (motor protection thermistor (PTC) conforming to DIN 44080-082)
m PT1000 (PTC with linear characteristic)
The selection is made using Parameter
which have an encoder with an electronic identification plate, the appropriate value is en-
tered at switch-on. On motors without an electronic identification plate, the encoder type
must be entered.
With the KTY84/130 and PT1000 temperature encoders, the current motor temperature
in °C is ascertained (displayed in parameter Z128.3–) and then checked against the two
temperature warning thresholds
ing 710 or 711 is issued. If the switch-off threshold is exceeded, Error 709 "Motor Over-
temperature Detected" is generated. The switch-off threshold in effect is displayed in
Parameter Z107.27–. On motors with an electronic identification plate, the appropriate
value is entered at switch-on. The standard value for Baumüller motors is normally 150°C.
With the temperature switch, the temperature value determined is compared to an inter-
nal permanently set switch-off threshold. This switch-off threshold corresponds to a resis-
tance value of 1100 ohms. If it is exceeded, Error 714 "Motor Overtemperature Detected
by Temperature Switch" is generated.
The temperature encoder can be connected either to the encoder input or to the connec-
tor X101 provided on the power unit. The setting for the connection is made in Parameter
