Extension Slots (EXT1 & EXT2)
The controller provides two extension slots (
Figure 3-43) located underneath the plastic lid at the control-
ler housing’s top face. They host optionally available extension cards (
Table 3-64) and thereby expand
the controller’s comprehensive motion control functionality even further.
•
EXT1
provides connectivity for a communication extension card, such as for EtherCAT.
With the optionally available «EPOS4 EtherCAT Card», the controller serves as slave in an
EtherCAT network, provides access for EtherCAT master control (such as Beckhoff TwinCAT), and
offers real-time operation in an Ethernet master/slave network. For further details see separate
document
«EPOS4 Communication Guide».
•
EXT2
provides connectivity for advanced signal extension cards, such as for additional absolute
sensors or customized signal extensions.
Using the respective optionally available EPOS4 cards, additional functions can be directly
accessed via the connector
“Extension Signal (X16)” on page 3-53.

Extension slots
An inserted extension card mechanically interlocks in both horizontal and vertical direction.
To insert or remove an extension card, proceed as follows (explained using an «EPOS4 EtherCAT Card»):
Hot plugging/hot swapping the card may cause hardware damage
Switch off the controller’s power supply before removing or inserting an extension card.
Electrostatic sensitive device (ESD)
• Wear working cloth and use equipment in compliance with ESD protective measures.
• Handle device with extra care.
