Glossary
Access Level
The degree of authorization a user has when using SED2
parameters. Also see User Access Level parameter P0003 in the
Parameter Reference Guide (125-3214).
ADC
Analog to Digital Converter; refers to analog inputs.
AOP
Advanced Operator Panel.
Boost
Applies an offset relative to the rated motor current. Boost is useful for
loads with high inertia. Also see Continuous Boost parameter P1310;
Acceleration Boost parameter P1311; Starting Boost parameter
P1312 in the Parameter Reference Guide (125-3214).
BOP
Basic Operator Panel.
CDS
Command Data Set.
Control Mode
Controls relationship between speed of motor and voltage supplied by
SED2. Also see Control Mode parameter P1300 in the Parameter
Reference Guide (125-3214).
DAC
Digital to Analog Converter; refers to analog outputs
DC Braking
Causes the motor to stop rapidly by applying a DC braking current
(current applied also holds motor shaft stationary). When the DC
braking signal is applied, the SED2 output pulses are blocked and the
DC current is not applied until the motor has been sufficiently
demagnetized. Also see Enable DC Braking parameter P1230.
