87 Hz
characteristic
Expanded manipulating range of the motor for con-
stant torque delivery. A motor with 400 V / 50 Hz in
star configuration can be expanded to 87 Hz in delta
configuration at this voltage.
Abscissa (Latin: abscissus = torn off, separated)
Horizontal axis in coordinates system
Actual value Return value of the external signal acquisition in
loop-controlled systems. In open-loop control sys-
tems the value calculated on the basis of preset
conditions.
Address coding
plug
Address coding of a device in a bus system by
means of a plug connector. An address in a bus
system must be unique within a fixed address
range.
ADS Application data set; data sets with preset solutions
for typical standardized applications, which also
serve as the basis for customizations. A customized
application data set can only be saved to one user
data set.
Analog/digital
ground
The analog and digital grounds are isolated from
each other in order to avoid transient currents. The
analog ground is connected directly to the inverter
module processor. It serves as the reference poten-
tial for analog reference input. The digital inputs and
outputs are isolated from it.
Application data
set (ADS)
Factory predefined parameter data set to solve typi-
cal applications.
