Stober PK - Connection to Siemens Drive Controllers; EIB 3392 S Interface

13.3 Connection to Siemens drive controllers
This chapter contains the information for connecting STOBER synchronous servo motors to drive controllers
of the above-named manufacturer which differs from connecting to STOBER drive controllers. You can find
all other information about STOBER synchronous servo motors in the respective chapter of this catalog.
STOBER has taken the following measures to minimize the effort of commissioning STOBER motors con-
nected to SINAMICS S120 drive controllers and avoid errors during parameterization:
• The commutation offset of the motor was set so that calibration by the customer is not necessary.
• Parameter lists are provided on request.
13.3.1 EIB 3392S interface
The EIB 3392S interface made by Heidenhain enables the connection of EnDat 2.2 encoders to Siemens
SINAMICS S120 drive controllers using the powerful DRIVE-CLiQ system interface. STOBER offers the EIB
3392S interface with the ID 1250663-01. In this design, the connector and the terminal assignment on the
EnDat 2.2 side are adapted to STOBER synchronous servo motors so that the interface can be connected and
commissioned without additional work.
Advantages
• Support for all DRIVE-CLiQ interface options
• Compact and robust industrial design
• Easy, fast commissioning
• No space or wiring necessary in the control cabinet
• Because the DRIVE-CLiQ electronics are located outside of the motor, it is not necessary to reduce the
performance data of the motor based on the temperature.
Features
Feature Description
Surrounding temperature for operation 0°C to 60°C
Protection class IP 65
Bending radius of the interface connection cable 75mm, freely movable
20mm, permanently installed
The EIB 3392S interface is connected to the plug connector of the motor on the EnDat 2.2 side. On the
DRIVE-CLiQ side, an original Siemens encoder cable with a length of up to 30m can be connected.
The EIB 3392S interface may only be connected to motors with a Pt1000 temperature sensor. The tempera-
ture sensor is connected to the EnDat 2.2 encoder inside the motor. The EIB 3392S interface transmits the
values from the temperature sensor over the DRIVE-CLiQ interface unchanged.
The housing of the EIB 3392S must be attached at the installation location. A cable clip can be used for this
purpose (see dimensional drawing).
Functional safety
Depending on the connected encoder and the downstream electronics, the EIB 3392S can be used in safety-
oriented applications up to Safety Integrity Level (SIL) 2 in accordance with EN 61508-1 / EN 61800-5-2 or up
to Category 3, PL d in accordance with EN ISO 13849-1.
The probability of a failure per hour (PFH) is 26 × 10
-9
for an installation altitude ≤ 1000m above sea level.
The EIB 3392S interface does not have any effect on the safe position that can be implemented by the mo-
tor encoder and the downstream electronics.
