Overview
SMC30 Sensor Module Cabinet-Mounted
The SMC30 Sensor Module Cabinet-Mounted is required to
evaluate the encoder signals of motors without a DRIVE-CLiQ
interface. External encoders can also be connected via the
SMC30.
以下encoder signals can be evaluated:
•
Incremental encoders TTL/HTL with and without wire break
detection (wire break detection is only available with bipolar
signals)
•
SSI encoders with TTL/HTL incremental signals
•
SSI encoders without incremental signals
The motor temperature can also be detected using KTY84-130/
PT1000 or PTC.
■
Design
The SMC30 Sensor Module Cabinet-Mounted features the
following connections and interfaces as standard:
•
1 DRIVE-CLiQ interface
•
1 encoder connection including motor temperature detection
(KTY84-130/PT1000 or PTC) via SUB-D connector or terminals
•
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 via a multi-color LED.
The SMC30 Sensor Module Cabinet-Mounted can be snapped
onto a TH 35 standard mounting rail in accordance with
EN 60715 (IEC 60715).
The maximum signal cable length between SMC30 modules and
encoders is 100 m (328 ft). For HTL encoders, this length can be
increased to 300 m (984 ft) 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.,
Phoenix Contact type SK8 or Weidmüller type KLBÜ CO 1.
The shield connection terminal must not be used as a strain relief
mechanism.
