keep inverter running on cancel

[rbresca]

Good morning,

I have an vacuum pump driven by an inverter (Axis object + Rexroth xFC01 peripheral). This inverter should keep running always.

I would like to switch on at ControlOn (or after a specific command) and keep it alwasy on.

Now I'm using Axis.POS_SETVELO to start the pump. The problem is that, as soon as I change mode, the inverter stops.

Is there a way to prevent this behaviour with the Axis Object like with the BasMove.OutputResetOnCancel ?

Should I throw away the Axis object and drive the inverter via binary and analog output?

The xFC peripheral by Bosch Connected Industry only has a drive interface, so I think there is no alternative than the Nexeed drive object (beside programming something new by your own).

The latest Application Guideline includes some examples how to exclude an unit from the cancel etc.
Keep in mind that the unit will then never be stopped automatically - also not in case of emergency stop.
