Checkt the values for TI and TO time on the bus. Also check that OB Servo is configured as syncronous to the bus and not with a free cycle. Regards Christoph

I have two drive on the machine in isochronous mode. One has no problem. Attachment TIA V15.1-2019-12-19-12-03-23.png (103 Downloads)

Do you use both inverters with the same configuration (SERVO/IPO) and the same controller cycles? Regards Christoph
