Over
voltage of the main power
circuit.
Check the main power
voltage or the regeneration module.
Specify the Weight/Inertia setting.
Check the load.
Check the robot. (Smoothness, backlash,
non-
smooth motion, loose belt tension,
brake)
Check the interference w
ith the
peripheral equipment. (Collision,
contact)
Check the model setting.
Check the power cable connection.
Check the robot power wiring. (Missing
pin, disconnection, short-circuit)
Check the power supply voltage. (Low
power supply voltage)
Replace the motor driver.
Replace the DMB.
Replace the motor.
5049
Over
current of the motor driver.
Check the power cable connection or
the robot internal wiring.
Check the short-circuit and earth fault of
the power line.
Replace the motor driver.
Replace the DMB.
5050
Over
speed during torque control.
Check the work motion speed range.
Check the motion speed during torque
control.
5051
15V PWM drive power supply failure.
Reboot the controller. Replace the
15V power supply.
Check the 15V power supply and cable
connection.
Replace the motor driver.
Replace the DMB.
5054
Overload of the motor. Decrease the
motion duty and the Accel.

5072
Servo alarm B.
5080
Motor is overloaded. Decrease the
duty and the Accel.
Lower the motion duty.
Check the Weight/Inertia setting.
Check the robot. (Backlash, large load,
loose belt tension, brake)
5098
High temperature of the encoder.
Decrease the duty.
Check the
reduction gear unit of the robot.
Wait until the temperature of the encoder
decreases.
Lower the motion duty.
Check the Weight/Inertia setting.
Check the robot. (Backlash, large load,
loose belt tension, brake)
5099
High temperature of the motor driver.
Clean the controller fan filter. Check
the ambient temperature. Decrease
the duty.
Clean the cooling fan filter.
Lower the motion duty.
Check the Weight/Inertia setting.
Lower the ambient temperature.
