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
motor current, DC voltage and motor speed at the time of the peak.
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
when the drive is running, 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 fall within that range.
Amplitude ranges
(parameters 36.40...36.49)
Amplitude logger 1 is fixed to monitor motor current, and cannot be reset. With
amplitude logger 1, 100% corresponds to the maximum output current of the drive
(I ). The distribution of samples is shown by parameters 36.20...36.29.
