We are experiencing high-frequency electrical noise affecting nearby 4-20mA pressure transmitter signals whenever our 45kW ABB ACS580 drive accelerates. The motor power cable is 4-core shielded. Should the braided copper shield be grounded at both the VFD PE terminal and the motor frame, or at the VFD side only to avoid ground loop currents?
