Overview
SMC30 Sensor Module Cabinet-Mounted
The SMC30 Sensor Module Cabinet-Mounted is required to eval-
uate the encoder signals of motors without a DRIVE-CLiQ inter-
face. External encoders can also be connected via the SMC30.
The following encoder signals can be evaluated:
•
Incremental encoders TTL/HTL with/without open-circuit
detection (open-circuit detection is only available with bipolar
signals)
•
SSI encoder with TTL/HTL incremental signals
•
SSI encoder without incremental signals
The motor temperature can also be detected using KTY84-130
or PTC thermistors.
■
Design
The SMC30 Sensor Module Cabinet-Mounted features the fol-
lowing connections and interfaces as standard:
•
1 encoder connection including motor temperature detection
(KTY84-130 or PTC) via SUB-D connector or terminals
•
1 DRIVE-CLiQ interface
•
1 connection for the electronics power supply via the 24 V DC
supply connector
•
1 PE connection
The status of the SMC30 Sensor Module Cabinet-Mounted is
indicated using a multi-color LED.
The SMC30 Sensor Module Cabinet-Mounted can be snapped
onto a TH 35 mounting rail according to EN 60715 (IEC 60715).
The maximum encoder cable length between SMC30 modules
and encoders is 100 m. For HTL encoders, this length can be in-
creased to 300 m if the A+/A- and B+/B- signals are evaluated
and the power supply cable has a minimum cross-section of
0.5 mm
2
.
The signal cable shield can be connected to the SMC30 Sensor
Module Cabinet-Mounted via a shield connection terminal, e.g.
type SK8 from Phoenix Contact or type KLBÜ CO 1 from Weid-
müller. The shield connection terminal must not be used as a
strain relief mechanism.
■
Integration
SMC30 Sensor Modules Cabinet-Mounted communicate with a
Control Unit via DRIVE-CLiQ.
■
Selection and ordering data
For the SINAMICS S150 and SINAMICS S120 Cabinet Modules,
the SMC30 Sensor Module Cabinet-Mounted can be ordered as
an option by specifying order code
