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 CMMT-AS.
3. Save settings in the CMMT-AS.
4. Switch off CMMT-AS.
5. Connect new encoder type.
6. Switch CMMT-AS back on.

[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).

[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

Controller

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

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. 28: 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 the network. This method is suit-
able 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
