Overview
SMC20 Sensor Module Cabinet-Mounted
The SMC20 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
SMC20.
The following encoder signals can be evaluated:
•
Incremental encoder sin/cos 1 V
pp
•
Absolute encoder EnDat 2.1
•
SSI encoder with incremental signals sin/cos 1 V
pp
(as of firmware version V2.4)
The motor temperature can also be detected using KTY84-130/
PT1000 or PTC.
■
Design
The SMC20 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
•
1 connection for the electronics power supply via the
24 V DC supply connector
•
1 PE connection
The status of the SMC20 Sensor Module Cabinet-Mounted is
indicated via a multi-color LED.
SMC20 Sensor Modules Cabinet-Mounted can be snapped onto
a TH 35 standard mounting rail in accordance with EN 60715
(IEC 60715).
The signal cable shield is connected via the encoder system
connector and can also be connected to the SMC20 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.
■
Integration
SMC20 Sensor Modules Cabinet-Mounted communicate with a
Control Unit via DRIVE-CLiQ.
