4.15.4 Clearing the Service Log

The flash memory stores up to 24 records. To save more logs, clear the service log memory.
Save the service log records using the VLT® Motion Control Tool MCT 10 before clearing the service log.
Clear the service log after a commissioning to remove any alarms that occurred during testing.
