Name Description
When Error Checked Error Processing Corrective Action
• The command speed is too high. • Reconsider the command speed.
A
• Servo system CPU fault. • Change the servo system CPU.
• There is excessive variation in the
position commands from the servo
system CPU; commanded speed is
too high.
• Check the commanded speed, and the
number of pulses per revolution and
travel value per revolution in the fixed
parameters.

M
Data error
• Noise has entered the commands
from the servo system CPU.
• Check the connection of the motion bus
cable connector.
• Check if the motion bus cable is
clamped correctly.
• Check if the motion bus cable is
clamped correctly.
• Check if any relays or valves are
operating in the vicinity.
A
• Servo system CPU fault. • Change the servo system CPU.
2036
M
Transmission error
• Fault in communication with the
servo system CPU
• Check the connection of the motion bus
cable connector.
• Check if there is a disconnection in the
motion bus cable.
• Check if the motion bus cable is
clamped correctly.
2042
M
Feedback error
• Encoder signal fault • Replace the servomotor.
• The ADU fan is at a stop. • Change the ADU fan.
• The continuous output current of
the ADU is exceeded.
• Reduce the load.
A
Amplifier fin
overheat
• ADU's thermal sensor fault. • Change the ADU.
2045
M
Fin overheating
• The heat sink in the servo amplifier
is overheated.
• Amplifier error (rated output
exceeded)
• Power repeatedly switched
ON/OFF during overload.
• Cooling fault
• If the effective torque of the servomotor
is high, reduce the load.
• Reduce the frequency of acceleration
and deceleration.
• Check if the amplifier's fan has
stopped.
(MR-H150B or higher)
• Check if the passage of cooling air is
obstructed.
• Check if the temperature inside the
panel is too high
(range: 0 to +55°C).
• Check if the electromagnetic brake was
actuated from an external device during
operation.
• Replace the servo amplifier.
• The thermal protector built in the
servo motor malfunctioned.
• Change the servo motor.
A
• The continuous output of the servo
motor is exceeded.
• Reduce the load.
• The servomotor is overloaded. • If the effective torque of the servomotor
is high, reduce the load.
• The servomotor and regenerative
option are overheated.
• Check the ambient temperature of the
servomotor (range: 0 to +40°C).
2046
M
Motor overheating
• The thermal protector incorporated
in the encoder is faulty.
At any time during operation Immediate stop
• Replace the servomotor.
