Ethernet POWERLINK
®
Ethernet POWERLINK
®
is a deterministic real-time protocol for standard
Ethernet. It is an open protocol managed by the Ethernet POWERLINK
®
Standardization Group (EPSG). It was introduced by Austrian automation
company B&R in 2001.
F
Feed-in cable
Hybrid connection cable between the Decentral Access Module (DAM 510)
and ISD 510/DSD 510 servo drive.
Feedback system
The feedback system measures the rotor position.
Fieldbus
Communication bus between controller and servo axis and system mod-
ules; in general between controller and field nodes.
Firmware
Software in the unit; runs on the control board.
Function block
Device functionalities are accessible via the engineering environment soft-
ware.
I
IGBT
The insulated-gate bipolar transistor is a 3-terminal semiconductor device,
primarily used as an electronic switch to combine high efficiency and fast
switching.
IRT
Isochronous Real-Time.
ISD
Integrated Servo Drive
ISD servomotor
Designates the ISD servomotor (without the drive electronics).
Installation elevation
Installation elevation above normal sea level, typically associated with a de-
rating factor.
L
LCP
Local control panel.
Loop cable
Hybrid connection cable between 2 decentral servo drives, with 2 M23 con-
nectors.
M
M12 connector
Connector (X4) for connecting I/O and/or encoder on the B side of the ad-
vanced version of the ISD 510/DSD 510 servo drive.
M23 connectors
Connectors (X1 & X2) for connecting the hybrid feed-in and loop cables on
the B side of the standard and advanced version of the ISD 510/DSD 510
servo drive.
M8 connectors
Fully functional real-time Ethernet port (X3) on the B side of the advanced
version of the ISD 510/DSD 510 servo drive. Connector (X5) for connection
of the LCP to the B side of the advanced version of the ISD 510/DSD 510
servo drive.
MSD
Multi-axis Servo Drive
Motor shaft
Rotating shaft on the A side of the servo motor, typically without a key
groove.
Multi-turn encoder
Describes an absolute encoder, in which the absolute position remains
known after several revolutions.
P
PELV
Protected extra low voltage is an electricity supply voltage in a range which
carries a low risk of dangerous electrical shock.
