Event Counters; Operational Monitoring; Canopen Abort Code - Sevcon Gen4 Applications Reference Manual

You can access the FIFO using objects 41X1
and the data is read from 41X2

Event counters

The controller provides 10 event counters at 4200
information about occurrences of one event. The allocation of event counters to events is user-
configurable however Gen4 will automatically count important events in unused counters. The
information recorded in each event counter is:

The time of the first occurrence

The time of the most recent occurrence

The number of occurrences

Operational monitoring

At objects 4300 and 4301
h
these quantities:

Battery voltage

Capacitor voltage

Motor current

Motor speed

Controller temperature
Two instances of the operational monitoring log are maintained. Service engineers can access
and clear the first log; the second is accessible and clearable only by Sevcon engineers. The
Customer copy is normally recorded and reset each time the vehicle is serviced. The Sevcon
copy records data over the controller's entire working life.

CANopen abort code

The controller will sometimes respond with a CANopen General Abort Error (08000000
