3 System Description
3.1 Overview
The VLT
®
Integrated Servo Drive ISD
®
510 system is a high-
performance decentral servo motion solution.
It comprises:
•
A central power supply VLT
®
Servo Access Box
(SAB
®
).
•
VLT
®
Integrated Servo Drives ISD
®
510.
•
Cabling infrastructure.
The decentralization of the drive unit offers benefits in
mounting, installation, and operation. Depending on the
application, the SAB can power up to 64 drives in a servo
drive system when using 2 hybrid lines. It generates a DC-
link voltage of 565–680 V DC
±
10% and guarantees high
power density. It has a removable local control panel (LCP),
and is based on the proven quality of a Danfoss frequency
converter.
The motion control is integrated into the servo drive so
that the motion sequences can take place independently.
This reduces the required computing power of the central
PLC and offers a highly flexible drive concept. Danfoss
offers libraries for various IEC 61131-3 programmable PLCs.
Due to the standardized and certified fieldbus interfaces of
the ISD devices, any PLC with an EtherCAT
®
master
functionality or Ethernet POWERLINK
®
managing node
functionality according to the standards can be used.
Hybrid cables are used to connect the drives, making
installation fast and simple. These hybrid cables contain
the DC-link supply, the Real-Time Ethernet, U
AUX
and STO
signals.
3.2 Servo Drive
ISD is the abbreviation of integrated servo drive, which is a
compact drive with an integrated permanent magnet
synchronous motor (PMSM). This means the entire power
drive system consisting of motor, position sensor,
mechanical brake, and also power and control electronics
is integrated into 1 housing. Additional circuits, such as
main low voltage supply, bus drivers, and functional safety
are implemented within the servo drive electronics. All
servo drives have 2 hybrid connectors (M23) that connect
power and communication signals from a hybrid cable. The
advanced version has 3 additional interfaces for external
encoder or I/Os, fieldbus devices, and for the local control
panel (LCP) to be connected directly.
LEDs on the top of the servo drive show the current status
(see
chapter 7.2 Operating Status Indicators for further
information). Data transfer takes place via Real-Time
Ethernet.
