- If P0552≠6 and any DI is configured for "Trace Function", the trigger will never occur as a result of the DI activation.
- These three programming options do not prevent the inverter from being enabled.
P0553 – Trace Sampling Period
Adjustable 1 to 65535
Range:
Properties:
Access groups 01 PARAMETER GROUPS
via HMI:
Description:
It defines the sampling period (time between two sampling points) as a 200 µs multiple.
For P0297 = 1.25 kHz, it defines the sampling period as a 400 µs multiple
P0554 – Trace Pre-Trigger
Adjustable 0 to 100 %
Range:
Properties:
Access groups 01 PARAMETER GROUPS
via HMI:
Description:
It is the data percentage that will be recorded before the occurrence of the trigger event.
P0559 – Trace Maximum Memory
Adjustable 0 to 100 %
Range:
Properties:
Access groups 01 PARAMETER GROUPS
via HMI:
Description:
It defines the maximum of memory that the user wished to reserve for the Trace Function points. The setting range,
from 0 to 100 %, corresponds to a reserve request of 0 to 15 KB for the Trace Function.
Each point stored by the Trace Function takes 2 bytes of memory. This parameter defines indirectly the number of
points that the user wishes to store with the Trace Function.
The memory area used by the Trace Function is shared with the memory for the SoftPLC applicative. When there is a
SoftPLC applicative in the inverter, the amount of memory actually available for the Trace Function may be smaller
than the value adjusted in P0559. The indication of the memory amount actually available is done by the read only
parameter P0560. For more details refer to the parameter P0560 description.
As the factory setting, P0559 = 0 %. In this case, there is no memory available for the Trace Function, because the
available 15 KB are reserved for the SoftPLC applicative.
