Pulse encoder:
An external, digital pulse transmitter used for feeding
back information on motor speed. The encoder is used
in applications where great accuracy in speed control
is required.
AWG:
Means American Wire Gauge, i.e., the American
measuring unit for cable cross-section.
Manual initialization:
Press the [CHANGE DATA] + [MENU] + [OK] keys at
the same time to carry out manual initialization.
60° AVM
Switching pattern called 60°
Asynchronous Vector
Modulation.
SFAVM
Switching pattern called
Stator Flux-oriented Asyn-
chronous
Vector Modulation.
Automatic motor adjustment, AMA:
Automatic motor adjustment algorithm, which deter-
mines the electrical parameters for the connected mo-
tor, at standstill.
On-line/off-line parameters:
On-line parameters are activated immediately after the
data value is changed. Off-line parameters are not ac-
tivated until OK has been entered on the control unit.
VT characteristics:
Variable torque characteristics, used for pumps and
fans.
CT characteristics:
Constant torque characteristics, used for all applica-
tions, such as conveyor belts and cranes. CT charac-
teristics are not used for pumps and fans.
MCM:
Stands for Mille Circular Mil, an American measuring
unit for cable cross-section. 1 MCM • 0.5067 mm
