[X3], encoder interface 2
The encoder interface [X3] is located on the front side of the device. The encoder
interface [X3] primarily serves to connect a second position encoder to the axis
(e.g. to enable precise positioning control for the axis or as a redundant meas-
uring system for safe motion monitoring).
Supported standards/protocols
Supported encoders
Digital incremental encoders with square-wave
signals and with RS422-compatible signal out-
puts (differential A, B, N signals)
ROD 426 or compatible
ELGO LMIX 22
Analogue SIN/COS incremental encoders with
differential analogue signals with 1 V
ss
HEIDENHAIN LS 187/LS 487 (20 µm signal
period) or compatible

[X3] is designed to be electrically compatible with [X2] but does not support all
encoders and functions like [X2].

[X10], SYNC IN/OUT
The interface [X10] is located on the front of the device. The interface [X10]
permits master-slave coupling. In the master-slave coupling, the axes of several
devices (slave axes) are synchronised via a device (master axis). The SYNC inter-
face can be configured for different functions and can be used as follows:
Possible functions
Description
Incremental encoder output
Output of a master axis that emulates encoder
signals (encoder emulation)
Incremental encoder input
Input of a slave axis for receiving the encoder
signals of a master axis

[X18], Standard Ethernet
The interface [X18] is located on the front of the device. The following can be
performed via the interface [X18] using the commissioning software:
–
Diagnostics
–
Parameterisation
–
Control
–
Firmware update
The interface is designed to conform to the standard IEEE 802.3. The interface
is electrically isolated and intended for use with limited cable lengths
Requirements for the connecting cable. For this reason, the insulation coordina-
tion approach differs from IEEE 802.3 and must conform instead to the applicable
product standard IEC 61800-5-1.

Tab. 25: Requirements for the connecting cable
The following connections are possible via the Ethernet interface:
Connections
Description
Point-to-point connection
The device is connected directly to the PC via an
Ethernet cable.
Network connection
The device is connected to an Ethernet network.
Tab. 26: Options for connection
The device supports the following methods of IP configuration (based on IPv4):
Methods
Description
Obtain IP address automatically (DHCP client)
The device obtains its IP configuration from a
DHCP server in your network. This method is
suitable for networks in which a DHCP server
already exists.
Fixed IP configuration
The device uses a fixed IP configuration.
The IP configuration of the device can be perma-
nently assigned manually. However, the device
can only be addressed if the assigned IP configu-
ration matches the IP configuration of the PC.
Factory setting: 192.168.0.1
