Hello, I have this kind of problem.
PAC Motion version 1.3 (received with this firmware version . never updated).
3 drives connected in Ethercat fieldbus. 1 virtual encoder.
Ethercat task: External, EVENT_ECM_DC, interval time 1ms
Additional task cyclic 100ms.
The system works fine. Average task time 250us. max 800us.
When I try to connect to the devce with PAC Configurator or Visualizazion using web browser
Ethercat task time goes up to over 8 ms and I have a errorstop because Lost of Synchronicity.
Someone has already found the same problem?
