Table 8- 17 Example: Electrical components for the suggested circuit
F 3RV10 circuit-breaker with current paths
connected in series (if required with mounted
auxiliary contact 3RV1901 to provide a feed-
back signal for the drive).
or Miniature circuit-breaker 5SX21 (if required with
mounted auxiliary contact to provide a feedback
signal for the drive).
Auxiliary contactor 3RH11
Varistor SIOVS14K30 (EPCOS)
Signal connection / motor protection
The motors can be connected to the converter system as follows.
Via the DRIVE-CLiQ interface
M17 round connector, 10-pin
M23 round connector, 17-pin
Identifier at the 14th digit of the article number
The connection is established using a MOTION-CONNECT cable
Additional information on connecting signals with DRIVE-CLiQ is provided at "Motors with
DRIVE-CLiQ interface (Page 389)".
Additional information on connecting signals without DRIVE-CLiQ is provided at "Motors
without DRIVE-CLiQ interface (Page 392)".
Motors with DRIVE-CLiQ interface
Motors designed for SINAMICS drive systems have an integrated encoder and temperature
evaluation system as well as an electronic rating plate.
The motors are connected to the converter system via a DRIVE-CLiQ interface.
The DRIVE-CLiQ interface supplies the motor encoder with power via the integrated 24 VDC
power supply. The DRIVE-CLiQ interface transfers the motor encoder and temperature
signals and the electronic rating plate data, e.g. a unique identification number, rating data
(voltage, current, torque) to the Control Unit.
