Hello,

I'm new to the forum and directly have my first question :-)
I'm using UCCNC with an AXBB-E controller and a Sourcetronic ST500 2,2kW VFD with Modbus.

Currently the VFD is controlled via analog output 0-10V and digital pins to control the VFD.
In case of an error of the VFD a VFD internal relais will be switched and the UCCNC e-stop is triggered.

I thought about trying to use Modbus to control the VFD and also get more information like output current, etc. to be displayed in UCCNC. I checked and there are two possibilities to use Modbus as plugin. The UCCNC built-in Modbus Master and the MODBUSEZ plugin from Dan.
I like the MODBUSEZ plugin because it's much less work to setup Modbus communication.

My biggest concern is, how to handle failure cases like e.g. communication break down or VFD error during execution of a job.
Do these plugins offer failure handling and can they be linked to e.g. the e-stop?

Would be nice if somebody has some experience with this!

Thank you,
Tobias
