5.15.4 Clearing the Service Log
The flash memory stores up to 24 records. To save new logs, clear the service log memory.
Save the service log records using the VLT® Motion Control Tool MCT 10 before clearing the service log.
The service log is stored in EEPROM in the control card and will be erased by initialization, that is when changing the power card.
Before changing the power card:
Click the Service Log icon to read the service log from the drive.
Copy parameters to a project in MCT 10.
Save the parameters including the service log in the project.
When loading the parameters back into the drive, the service log is not included.
Clear the service log after a commissioning to remove any alarms that occurred during testing.
Procedure
Select option
[5] Clear Service Log
in
parameter 14-22 Operation Mode
.
Power cycle the drive. Clearing the service log extends the power-up time by approximately 1 s.

Clear logs Service log full: 28 [M26]
.
Bit 25 is set high in
parameter 16-96 Maintenance Word
(0x2000000).
Performing the drive initialization does not clear the service log memory.
5.15.6 Reading the Service Log Information
