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
