Signal Ground and HV Com are all connected in the drive. The HV and PWM outputs carry high currents, and
the signal circuits and I/O are low-current circuits. Circuits highlighted in green in the graphic below are isolated
from Signal Gnd to avoid ground-loops with external equipment.
User equipment connecting to the drive’s non-isolated circuits should have a circuit ground that is at the same
potential as the drive’s Signal Ground.
