9.25.1 About the break line ground judgement function
If the current flowing through the break line exceeds the capacity of the control power
supply unit, the DC 24V power supply will be disconnected by the protective circuit of the
control power supply unit; then an alarm “1683 DC24V POWER SUPPLY FAILURE(SV)”
occurs.
This function identifies the position where the ground fault occurred after arising the alarm
“1683 DC24V POWER SUPPLY FAILURE(SV)”. It is able to identify which axis break line
does the ground fault occur by inspecting the each axis from the programming pendant.
Identify the ground fault of the break line by the following methods.
1) Turn the SERVO ON the group which the ground fault occurs.
2) Discharge the any axis break, and then confirm if the DC 24V power supply will be
disconnected.
