1S-series with Built-in EtherCAT Communications and Safety Functionality User's Manual (I621)
Assumed cause
• Inrush current prevention
circuit failure
• There is a short circuit
between B2 and N2/N3.
• Regeneration circuit failure
• Noise into wiring of the
external regeneration resis-
tor.
• Error of the EtherCAT slave
communications controller
or false detection when the
AL status code is 0051 hex
• Error access from the
non-OMRON EtherCAT
master when the AL status
code is 0050 hex
• There is a short-circuit,
ground fault, or contact fail-
ure on the U, V, or W motor
cable
• There is a short-circuit on
the wiring of External
Regeneration Resistor or
the resistance value is small
• The insulation resistance
failed between the U, V, or
W motor cable and the
motor ground wire
• Servo Drive failure
• False detection due to a
data read error that was
caused by excessive noise
• Hardware failure
