Overview
The SMC30 Sensor Module Cabinet-Mounted is required to
evaluate the encoders 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
following interfaces as standard:
•
1 DRIVE-CLiQ interface
•
1 encoder connection, including motor temperature detection
(KTY84-130 or PTC) via SUB-D connector or terminals
•
1 connection for the electronics power supply via the 24 V DC
power supply connector
•
1 PE/protective conductor 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 standard mounting rail acc. to EN 60715
(IEC 60715).
The maximum encoder cable length between SMC30 modules
and encoders is 100 m (328 ft). For HTL encoders, this length
can be increased 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

.
The signal cable shield can be connected to the SMC30 Sensor
Module Cabinet-Mounted via a shield connection terminal, e.g.,
Phoenix Contact type SK8 or Weidmüller type KLBÜ CO 1.
■
Integration
SMC30 Sensor Modules Cabinet-Mounted communicate with a
Control Unit via DRIVE-CLiQ.

More information
Risk of encoder failures by encoder signal disturbances
Frictional (static) electricity can occur if the belt and belt pulley
materials are unfavorably matched. This static electricity can
discharge over the motor shaft and encoder and cause spurious
encoder signals. A belt made of anti-static material (conductive
polyurethane compound) can be used to mitigate this risk.
