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.
• Parameter 1 shows the share of samples that have fallen in range 0... 10%
of the reference value during the time that the logging has been active.
• Parameter 2 shows that share of samples that have fallen in range
10...20% of the reference value during the time that the logging has been
active
• etc.
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
max
). The maximum output current values are listed in the section
Ratings
in the
Hardware manual
of the drive. The measured current is logged
continuously. The distribution of samples is shown by parameters
