Danfoss VLT Integrated Servo Drive ISD 510 System, Design Manual

Page: 16 / 86

2.3.3.2 EtherCAT ®
To connect additional SAB units in the same EtherCAT
®
network, use an RJ45 to RJ45 network cable from the
Ethernet X2 connection on the 1 st SAB to the Ethernet X1
connection on the 2
nd
SAB, and so on.
2.4 EtherCAT ®
with Redundancy
Ring redundancy can be achieved using a special cabling
scheme. Connect the fieldbus extension cable to the last
servo drive on the line and connect the other end of the
cable with an Ethernet CAT5 cable. Settings must also be
made in the engineering environment; see the
corresponding online help for further information.

Component Description
ISD 510 servo
drive Motors with integrated signal and power
electronics. They are mounted decentrally in the
application and have advanced motion control
functionality on board.
Servo Access
Box (SAB) Central supply and access unit for mounting
inside a control cabinet. The SAB is the power
supply for the ISD 510 servo drives and is the
central access point for the fieldbus.
Hybrid cable There are 2 types of hybrid cable:
•
Feed-in cable: Connects the SAB to the 1
st
servo drive.
•
Loop cable: Connects the servo drives in an
application in daisy-chain format. Speed
connectors minimize installation time, cost,
and risk of failures.
Local Control
Panel (LCP) Graphical user interface for diagnostic and
operating purposes. The LCP is mounted on the
SAB but can be removed and connected to the
servo drive via connector X5 (advanced version
only). The LCP can be used for the ID
assignment of the advanced servo drives. The ID
assignment is started via LCP and the LCP also
indicates if the procedure is finished.
External
encoder An external encoder can be connected to each
SAB and servo drive in the system.
PLC
PLC with Ethernet POWERLINK
®
and EtherCAT
®
fieldbus master functionality.
STO Safe torque off feature can be provided via
external safety circuits.
Analog/Digital
Sensor Connection to the servo drives is possible.
