8.8.3 [X2], Encoder interface 1
The encoder interface [X2] is located on the front of the device. The encoder inter­
face [X2] primarily serves to connect the position sensor integrated into the
motor.

NOTICE!
Damage to the sensor when sensor type is changed.
The servo drive can provide 5 V or 10 V sensor supply. Through configuration of
the sensor, the supply voltage is established for the sensor. The sensor can be
damaged if the configuration is not adjusted before connection of another sensor
type.
•
When changing the sensor type: Comply with specified steps.
Change of encoder type
1. Disconnect encoder from the device.
2. Set up and configure new encoder type in the CMMT­AS.
3. Save settings in the CMMT­AS.
4. Switch off CMMT­AS.
5. Connect new encoder type.
6. Switch CMMT­AS back on.

Connecting the encoder cable shield
1. On the device side, connect the encoder cable shield to the plug housing.
2. On the motor side, connect the encoder cable shield to the encoder or
encoder plug.
8.8.4 [X3], Encoder interface 2
The encoder interface [X3] is located on the front of the device. The encoder inter­
face [X3] primarily serves to connect a second position sensor to the axis (e.g. to
enable precise positioning control for the axis or as a redundant measuring sys­
tem for safe motion monitoring).

encoders and functions like [X2].
8.8.5 [X10], SYNC IN/OUT
The interface [X10] is located on the front of the device. The interface [X10] per­
mits master­slave coupling. In the master­slave 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
Pulse direction input Input of a slave axis for receiving the pulse direc­
tion signals or count signals containing up­
count/down­count pulses

8.8.6 [X18], Standard Ethernet
The interface [X18] is located on the front of the device. The following can be per­
formed 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
è
Tab. 25 Requirements for the connecting cable. For this reason, the insulation
coordination approach differs from IEEE 802.3 and must conform instead to the
applicable product standard IEC 61800­5­1.
Requirements for the connecting cable
Characteristics CAT 5, patch cable, double shielded
Max. cable length 30 m
Tab. 25 Requirements for the connecting cable
The following connections are possible via the Ethernet interface:
Connections Description
Point­to­point 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 per­
manently assigned manually. However, the
device can only be addressed if the assigned IP
configuration matches the IP configuration of the
PC.
Factory setting: 192.168.0.1
