Description
The Regeneration Load
Ratio (4150-81 hex)
exceeded 85%.
The motor vibration, which
was higher than or equal to
the level set in the Vibra-
tion Detection - Detection
Level (3B70-01 hex), was
detected.
A command could not be
executed.
An EtherCAT communica-
tions error occurred more
than one time.
Restart was performed.
The safety input OFF state
was detected via the safety
input signal or EtherCAT
communications.
Assumed cause
• The regeneration process-
ing is set inappropriately
• The Regeneration Resistor
is selected inappropriately
• The Regeneration Resistor
is used for continuous
regenerative braking
• The applied power supply
voltage is higher than the
specified value
• Regeneration Resistor fail-
ure
• The control parameter is set
inappropriately
• The rigidity decreased due
to mechanical looseness or
wear
• The Switch ON command
was received
• The Enable operation com-
mand was received
• An operation command in
the prohibition direction was
received after the immedi-
ate stop by the Drive Prohi-

Position Limit
• Homing started
• The positioning start com-
mand was received in the
Profile position mode
• An EtherCAT communica-
tions cable is disconnected,
broken, short-circuited, or
has a contact failure in a
daisy chain configuration.
• In a ring topology configura-
tion, the ring disconnection
status occurred.
• In a ring topology configura-
tion, the ring disconnection
status was fixed.
• Noise
• Failure of the EtherCAT
physical layer of a Servo
Drive
• Restart was performed
• The cable is disconnected
or broken
• The STO input was turned
OFF via EtherCAT commu-
