Hi everyone,
The network include 4 remote control panels, every panel include at least 10-15 danfoss VLT-FC300 ethernet drives linked to the network with an AB switch and controlled by Controllogix 5000. Sometimes, a motor stops for few seconds (see minutes) and restart by itself. no fault on the display. but for some reason, i read a small negative value in the drive feedback Hz (-1,...) if the motor is still stopped.
Thanks for your help
