IL•1F CANopen DS301 9 Glossary
Fieldbus interface 95
9.2 Terms and Abbreviations
AC Alternating current
CAN (Controller Area Network), standardized open fieldbus as per ISO
11898, allows drives and other devices from different manufacturers to
communicate.
CANopen Device- and manufacturer-independent description language for com-
munication via the CAN bus
CiA CAN in Automation, CAN interest group, standardization group for CAN
and CANopen.
COB ID Communication OBject IDentifier; uniquely identifies each communica-
tion object in a CAN network
DC Direct current
Default value Factory setting.
DriveCom Specification of the DSP402 state machine was created in accordance
with the DriveCom specification.
DS301 Standardizes the CANopen communication profile
DSP402 Standardizes the CANopen device profile for drives
E Encoder
EDS (Electronic Data Sheet); contains the specific properties of a product.
Electronic gear Calculation of a new output speed for the motor movement based on the
input speed and the values of an adjustable gear ratio; calculated by the
drive system.
EMC Electromagnetic compatibility
EMCY object Emergency Object
Encoder Sensor for detection of the angular position of a rotating component. In-
stalled in a motor, the encoder shows the angular position of the rotor.
Error Discrepancy between a computed, observed or measured value or con-
dition and the specified or theoretically correct value or condition.
Error class Classification of errors into groups. The different error classes allow for
specific responses to faults, for example by severity.
Fault Operating state of the drive caused as a result of a discrepancy between
a detected (computed, measured or signaled) value or condition and the
specified or theoretically correct value or condition.
Fault reset A function used to restore the drive to an operational state after a de-
tected error is cleared by removing the cause of the error so that the er-
ror is no longer active (transition from operating state "Fault" to state
"Operation Enable").
I/O Inputs/outputs
Input device A device that can be connected via the RS232 interface; either the hand-
held HMI device or a PC with commissioning software.
Limit switch Switches that signal overtravel of the permissible range of travel.
