Black Box Feature

La función Black Box puede utilizarse para ayudar a encontrar la fuente de una perturbación. Los datos se guardan de forma automática cuando
se produce una perturbación que provoca la detención del variador. Los datos registran los momentos precedentes a la perturbación y el estado
del variador cuando esta se produce. Los datos se transfieren a una tarjeta SD para su análisis fuera de línea.

BLACK BOX FILE FORMAT

When copied to an SD card, the black box feature creates one file for each trip event, or record. The files are called "blackbox_xxxx.csv" where
xxxx is replaced with a decimal number that is incremented automatically by the drive every time a trip occurs.
The data recorded in the lead up to the trip is:
•
Up to four user defined parameters
•
Output Current in phases U and V expressed as a percent of motor rating
•
The rotor electrical frequency in Hz.
•
The demanded electrical frequency in Hz
•
The DC Link volts, (parameter 0392 DC Link Voltage)
•
The temperature of the control card PCB in centigrade, (parameter 0406 CM Temperature)
•
The temperature of the heatsink in centigrade, (parameter 0407 Heatsink Temperature)
•
The sequencing control word, (parameter 0644 Control Word)
•
The sequencing status word, (parameter 0641 Status Word)
•
The input and output digital signals on the stack, words 1 and 2.
•
The control card digital output and input latches.
•
Various digital inputs to the micro-controller.
•
Trip latch state
•
