Table 2.14 Servo Amplifier Error List (2000 to 2799) (Continued)
Error Cause
Description
• Error in data received from the servo
system CPU
• There is excessive variation in the
position commands from the servo
system CPU; commanded speed is too
high.
• Noise has entered the commands from
the servo system CPU.
• Fault in communication with the servo
system CPU
• Encoder signal fault
• The heat sink in the servo amplifier is
overheated.
• Amplifier error (rated output exceeded)
• Power repeatedly switched ON/OFF
during overload.
• Cooling fault
• The servomotor is overloaded.
• The servomotor and regenerative option
are overheated.
• The thermal protector incorporated in
the encoder is faulty.
• An overload current of about 200% has
been continuously supplied to the servo
amplifier and servomotor.
• The servo amplifier and servomotor
were overloaded at a torque close to
the maximum torque (95% or more of
the current control value).

Corrective Action
• Check the connection of the motion bus cable.
• Check if there is a disconnection in the motion
us cable.
• Check if the motion bus cable is clamped
correctly.
• Check the commanded speed, and the number
of pulses per revolution and travel value per
revolution in the fixed parameters.
• 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.
• 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.
• Replace the servomotor.
• 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.
• If the effective torque of the servomotor is high,
reduce the load.
• Check the ambient temperature of the
servomotor (range: 0 to +40°C).
• Replace the servomotor.
• Check if there has been a collision at the
machine.
• If the load inertia is very large, either increase
the time constant for acceleration and
deceleration or reduce the load.
• If hunting occurs, adjust the position loop gain in
the servo parameters.
• Check the connection of U, V, W of the servo
amplifier and servomotor.
• Check for disconnection of the encoder cable.
• Replace the servomotor.
• Check if there has been a collision at the
machine.
• If the load inertia is very large, either increase
the time constant for acceleration and
deceleration or reduce the load.
• If hunting occurs, adjust the position loop gain /
position control gain 1, 2, speed loop gain/
speed control gain 1, 2 in the servo parameters.
• Check the connection of U, V, W of the servo
amplifier and servomotor.
• Check for disconnection of the encoder cable.
• Replace the servomotor.
• If the voltage of the bus in the servo amplifier
has dropped (charge lamp has gone out),
replace the servo amplifier.
