96 Program features
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
(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 36.20…36.29.
