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. 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.
• 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 (

). The maximum output current values are listed in the section
