Event 35: Watchdog
The drive controller is interrupted:
§
The power unit is disabled and axis movement is no longer controlled by the drive controller

Number
Cause
Check and action
1: Core 0 – 2: Core 1
Microprocessor at full load
Check the runtime utilization using the scope
image (E191) and reduce it using a longer cycle
time if necessary (A150)
Microprocessor faulted
Check the connection and shielding and correct
them if necessary; replace the drive controller
if necessary
