The motor torque displayed by axis data
exceeded rated torque for a long time(a few
seconds - a few minutes). It may have
burned the motor.
• The wrong wiring, the breaking of the
UVW wire for the motor
• The type of motor was not correct.
• The motor was moved by external power.
• It interfered with an outside equipment.
• Defective WRCA01, WRCF01 circuit board
• Defective amplifier
• Defective motor(encoder)Check whether the robot interferes with
the outside equipment. If the robot interferes, remove the cause.
• Check the connection of UVW wire of
motor again. And check the breaking of
the wire.
• There is a possibility the robot moves by extra load.
Check the motion status of
robot again and reduce the teaching
speed. Then confirm the reoccurrence.
