Defines the Sercos bus cycle time in ns.
In V1.31.10.0, only 1 ms CycleTime is permissible.
For versions V1.32.X.0, the cycle time can be set to either 1, 2 or 4 ms. The values must be entered in ns (1000000 ns, 2000000 ns, 4000000 ns).
If any deviating numerical values are entered, they are corrected automatically as follows:
|
Entering |
Cycle time |
|---|---|
|
From 0000000 to 1999999 ns |
Is turned into 1000000 ns |
|
From 2000000 to 3999999 ns |
Is turned into 2000000 ns |
|
From 4000000 to 9999999 ns |
Is turned into 4000000 ns |
The CPU load (AvailableLoad) is a determining factor when choosing the cycle time.
NOTE: If the CycleTime is changed, the controller must be reset. In V1.32.6.0, download of the application is followed by a message indicating that a cold start-up of the controller has to be executed in order to apply the values.
Proceed as follows: Transfer the program to the controller (download) and then execute a cold start-up of the controller.
The maximum number of real Sercos slave devices depends on the:
oPacDrive controller type
oSercos slave device type
oConfigured functions (DriveIO or DriveTouchprobe)
