BACKWARD COMPATIBILITY NOTES

Version 2.3.0 has included some important modifications that could change the system behaviour.

Torque and current loops

The current / torque loop control performance has been improved decreasing the computation time between the input reading and the output generation.

The new implementation allows to reach higher bandwidths and smoother response for the same controller parameters (PI) compared to older FW versions. However, this improvement could slightly modify the behaviour of some already deployed applications. It is highly recommended to review the controller parameters from older motor configurations.

Monitoring

The next features has been modified or added in the monitoring functionality:

The maximum sampling rate is 10 kS/s for all mode of operation
The monitoring is now available in open loop modes
All PDO mappable and read-only registers can be mapped into the monitoring channels.

Refer to EMCL Manual for further information

Macros

Macros execution time has been modified to be more deterministic.

It is highly recommended to review the system behaviour if it is using macros for operation.
