4.15.3 Service Log

The service log function saves detailed log information of a 5-second interval when alarms occur. Service technicians can analyze
this information to troubleshoot and optimize the drive.
The drive can save up to 24 service log records in the flash memory.
Find the list of alarms that trigger a service log record in
trips/alarms, for example, Safe Torque Off, do not trigger a service log record.
Sampling rate
There are 2 periods with different sampling rates:
• Slow samples: 20 samples at a rate of 250 ms resulting in 5 s of history before the trip.
• Fast samples: 50 samples at a rate of 5 ms resulting in 250 ms of detailed history before the trip.
To enable the real-time clock (RTC) stamp, use the real-time clock module. If real-time clock is not available, the operating time in
parameter 15-32 Fault Log: Time is recorded.
