Interface to the motor
Motor temperature monitoring
Either PTC thermistors or linear temperature sensors (KTY84-
130) can be connected. One input is provided on the Standard
CUD and one input on the Advanced CUD option for this pur-
pose. An alarm or fault message can be parameterized for PTC
thermistors. When using a KTY84-130, one threshold can be
entered for an alarm and one threshold for shutdown (trip). The
limit values are displayed and entered in °C.
In addition, a thermo switch can be evaluated by the Advanced
CUD (option). A parameterizable alarm or fault message can be
output when the thermo switch responds (this is a binary switch-
ing signal). The evaluation is realized via a binary user-assign-
able input.
Brush length monitoring
The brush length is monitored using a floating microswitch; the
shortest brush is evaluated. If the useful brush life has expired,
then the microswitch opens; an alarm or fault message can be
parameterized. The evaluation is realized via a binary user-as-
signable input.
Monitoring the motor fan airflow
The airflow is monitored by an airflow monitor integrated in the
airflow circuit of the motor fan. When this responds, an alarm or
fault message is issued. The evaluation is realized via a binary
user-assignable input.
Siemens DC motors
Although the end of DC technology has been forecast now for
many years, we will keep hold of our DC technology and it will
remain in our portfolio. When all is said and done, DC motors
have proven themselves in daily use for decades now and they
are essentially indispensable.
In conjunction with the SINAMICS DC MASTER converters, they
always form the ideal team – wherever favorably-priced drive
technology and the highest degree of availability are demanded.
These motors can also be used where space is restricted thanks
to their compact and modular design.
Further, an extensive range of equipment and devices for mount-
ing on the motor is available. A wide range of monitoring and
diagnostic options facilitate reliable and disturbance-free
operation.
Detailed specifications regarding quality assurance and im-
provement are integrated in all of the various operations and
processes – from motor development through to production
and service. Quality management coordinates the interaction
between all of the company processes to ensure error-free and
smooth processes.
It goes without saying that our stringent quality requirements
also apply to our suppliers. All of the suppliers must seamlessly
integrate themselves into our quality management system.
The result: Only fault-free and high quality materials are released
for use in our motor production.
