A.2.2 Statistic data
Statistic data group together the operating states from the past that are relevant to the load.
Examples of statistic data
The following values are examples of statistic data:
• Operating hours
– Motor operating hours
– Operating hours of the device (3RW5 Soft Starter)
• Number of motor overload trips
• Number of starts motor CW
• Number of starts motor CCW
A complete overview of the statistic data can be found in chapter Data set 95: Statistic data
(Page 174).
A.2.3 Maximum pointer
Maximum pointers are stored extreme values of measured values from the past and are used for
preventive diagnostics. Maximum pointers are stored in the device and can be deleted at any
time.
Examples of maximum pointers
The following values are examples of maximum pointers:
• Number of motor overload trips
• Minimum and maximum phase current I L1, I L2, I L3
• Minimum and maximum line voltages
• Minimum and maximum line frequency
A complete overview of the maximum pointers can be found in chapter Data set 96: Maximum
pointer (Page 175).
A.3 Process data and process images
The basic functions of the 3RW5 soft starter are controlled and monitored in the process data in
the process images.
The process images can be transferred as follows:
• Cyclically in the eldbus protocol
• Acyclically using data sets
