Sine Wave Function; Triangular Function - Elektro-Automatik ELR 9000 Betriebsanleitung

► How to start and stop a function
1.
The function can be started either by tapping
currently switched off. The function then starts immediately. In case START is used while the DC input is
still switched off, it will be switched on automatically.
During the progress of the functions sine wave, rectangular wave, triangular wave, trapezoi-
dal wave or ramp no actual values are displayed.
2.
The function can be stopped either by tapping
is a difference:
a) The
b) The "On/Off" button stops the function and switches the DC input off.
Any device alarm (overvoltage, overtemperature etc.) or protection (OPP, OCP) or event with
action = Alarm stops the function progress automatically, switches off the DC input and reports
the alarm in the display.

Description
A = Amplitude of the signal to be generated
Off = Offset, based on the zero point of the mathematic sine
curve, may not be smaller than the amplitude.

Application and result:
A normal sine wave signal is generated and applied to
the selected set value, e.g. current (I). At a constant
input voltage the current input of the load will follow a
sine wave.
For calculating the maximum power input the amplitude
and offset values for the current must be added.
Example: with an input voltage of 100 V and sin(I) se-
lected, set the amplitude to 30 A and the offset to 50 A.
The resulting maximum input power is then achieved at
the highest point of the sine wave and is (30 A + 50 A)
* 100 V = 8000 W.

A = Amplitude of the signal to be generated
Off = Offset, based on the foot of the triangular wave
