B.2 Historical Logger
The NXGPro+ provides a historical log for continuously logging a series of records consisting of
10 entries. The entries consist of the drive state, seven user programmable variables, and two
fault data words. This information is sampled every speed loop update cycle, and is stored in a
circular bu󹪜er. When a fault condition occurs, 491 pre-fault samples and 20 post-fault samples
are recorded along with the current sample (for a total of 512 samples) in nonvolatile memory
along with the time/date stamp. This information stays in nonvolatile memory until the next
fault occurs, at which time the old information is overwritten. To preserve multiple records of
historical logs, the user can enable (default is enabled) saving the historical logs into the event
log 󹪝le. To prevent overrunning the event log with too much historical log information, the
number of pre-fault samples is reduced to 57 samples. The user-de󹪝ned variables are to be
selected from a prede󹪝ned pick list of variables for historic log. The fault information is stored in
the four fault data words.
