Internal power and ground connections of VSD-E and XE

VSD-E and VSD-XE internal power wiring illustrated.

  • A,B,C and D - the motor output phases
  • GND - ground or 0V potential
  • FG - frame ground (cable shields connect here)
  • 12V - logic supply voltage
  • HV+ - high voltage supply of 12-160VDC

Frame ground[edit | edit source]

FG is internally connected to GND via RC circuit. The capacitor in the circuit passes high frequency interference to ground and resistor prevents static voltage build-up.
