This term:

Has the following definition:

bandwidth

Bandwidth is the frequency range from

ω = 0 to the point at which the magnitude response of the speed

regulator is 0.707 of (or 3db below) its zero frequency (steady-state) value. The bandwidth indicates the rise
time or speed of response of the speed regulator.

ω = 2πf, where f is Hz or cycles per second.

destination parameter (read
and write parameters)

Destination parameters accept data from other parameters. The drive uses this data to perform the desired
functions. An example of a destination parameter is Speed Ref 1 (parameter 29), which can accept a speed
reference from a device such as a PLC. Throughout this manual, the following symbol indicates a destination
parameter:
Destination parameters may also be called sink parameters.

display units

Display units are the units that are displayed on the Human Interface Module (HIM). Display units are units such
as Hz, volts, and rpm, and are converted to and from drive units by the HIM.

drive units

Drive units are the actual values of the parameters as stored within the drive parameter table. The drive units
are converted to display units that are shown on the Human Interface Module (HIM). Drive units may also be
called internal units.

See non-volatile memory.

frame size

A single-letter designator used to identify the various drive sizes. Frame sizes are frequently referred to instead
of the kW or horsepower rating they represent. Refer to Chapter 1, Overview, to determine the frame size for
your drive.
