VLT AutomationDrive FC 301/302
Programming Guide
With the dynamic offset feature, it is possible to distribute execution of relative master offset and marker correction while synchro-
nizing over a specific distance instead of using Ramp 1 (parameter group 3-4* Ramp 1) and parameter 3-28 Master Offset Speed Ref.
With this feature, an offset execution profile is calculated based on:
• Offset execution distance
• Parameter 4-24 Max Speed
• Actual master speed
•
Parameter 7-99 Min Ramp Time
The offset execution distance can be related to the distance traveled by the master or the follower, selected in parameter 17-96
Execution Distance Relation. The execution distance relation is automatically extended if required due to speed/ramp limitation. This
situation can be signaled in the fieldbus status word by selecting [22] Execution distance extended in parameter 8-13 Configurable
Status Word STW.
Parameter 17-96 Execution Distance Relation
Table 965: Parameter 17-96 Execution Distance Relation
17-96 Execution Distance Relation
Default value: [0] Master related
Conversion index: -
This parameter is only available with software version 48.9X.
Select whether the value set in parameter 17-95 Offset Execution Distance is related to the distance traveled by the master or by the
follower.
Option Name
[0]* Master related
[1] Follower related
5.18 Parameter Group 18-** Data Readouts 2
5.18.1 18-0* Maintenance Log
The following parameters are only available in FC 302:
-
Parameter 18-00 Maintenance Log: Item
-
Parameter 18-01 Maintenance Log: Action
-
Parameter 18-02 Maintenance Log: Time
-
Parameter 18-03 Maintenance Log: Date and Time
This group contains the last 10 preventive maintenance events. Maintenance log 0 is the latest and maintenance log 9 is the oldest.
By selecting 1 of the logs and pressing [OK], the maintenance item, action, and time of the occurrence are shown in parameter 18-00
Maintenance Log: Item – parameter 18-03 Maintenance Log: Date and Time.
The alarm log key allows access to both alarm log and maintenance log.
