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.
