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 age points wide, and displays the age of the
collected samples that have fallen within that range.
You can view this graphically with the assistant panel or the Drive composer PC tool.
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 ), which is listed in the Hardware manual. The measured current is logged
max
continuously. The distribution of samples is shown by parameters 36.20...36.29.
