Load analyzer

Peak value logger


The user can select a signal to be monitored by a peak value logger. The logger
records the peak value of the signal along with the time the peak occurred, as well as
line current, DC voltage and power at the time of the peak. The peak value is sampled
at 2 ms intervals.

Amplitude loggers


The control program has two amplitude loggers.
For amplitude logger 2, the user can select a signal to be sampled at 200 ms
intervals, and specify a value that corresponds to 100%. The collected samples are
sorted into 10 read-only parameters according to their amplitude. Each parameter
represents an amplitude range 10 percentage points wide, and displays the
percentage of the collected samples that have fallen within that range.
Amplitude ranges (parameters 136.40...136.49)
Amplitude logger 1 is fixed to AC current
With amplitude logger 1, 100% corresponds to the maximum current of the drive.
The measured current is logged continuously. The distribution of samples is shown
by parameters 136.20...136.29.
