John, thank you! I owe you at least few beers! It works with one and also both motors attached to VFD. Thanks to everybody, who shared their thoughts and tried to solve my issue! Yes, I will have separate overcurrent protection relay for each motor to protect them. They have only 3 pairs of contacts - for motor phases, no auxiliary contacts, so I do not see an easy way to turn off/stop VFD, when any of them would trip. But operator will definitely see that material is not passing through normally and stop the device quickly.
