SMC30 Sensor Module Cabinet-Mounted (option K50)

4.11.22.1

Description

The SMC30 Sensor Module is used for determining the actual motor speed. The signals
emitted by the rotary pulse encoder are converted here and made available to the closed-
loop controller via the DRIVE-CLiQ interface for evaluation purposes.
In conjunction with SINAMICS G150 the following sensors can be connected to the SMC30
Sensor Module:
● TTL encoder
● HTL encoder
● KTY or PTC temperature sensor

Table 4- 66
Note
Because the physical transmission media is more robust, the bipolar connection should
always be used for HTL encoders. The unipolar connection should only be used if the
encoder type does not output push-pull signals.
NOTICE
Only one encoder system may be connected to the encoder module, either at X520 or at
X521/X531. The corresponding unused interface must not be used.
