Representation
For Pin 1 / Pin 8: The associated temperature channel (T1) can be assigned parameters as an individual channel or together
in combination with the second temperature channel (T2) at interface X120.
(For parameterization, see the
For Pin 6 / Pin 9: At an encoder supply of 5 V, the voltage drops on the encoder supply cables are recorded and compensated
by means of the sense cables. For this purpose, the encoder supply is adjusted to the SIMOTION D410.
NOTICE
Motor overheating due to an incorrectly connected KTY temperature sensor
A sensor connected with the incorrect polarity cannot detect the motor overheating.
Connect the KTY temperature sensor with the correct polarity.
For more information on the temperature sensors and how to use them, see the
S120 Commissioning Manual, in Chapter Temperature sensors for SINAMICS components.
