ground

There is fault in the
current detection
circuit
 Check if the
connection of the

control panel
ETH2 Grounding shortcut fault 2

The output of the
inverter is short
circuited with the
ground
 There is fault in the
current detection
circuit
 Check if the
connection of the
motor is normal or not
