Problem 1: The reason why the servo motor alarms the overload

If the drive resistance is too great, check the drive system.

Q2: What is the difference between stepper motor and servo motor overload capacity?

Question 3: Is the servo motor overload necessarily related to the current?

As an element of motor torque output, its overload must be due to the large shaft torque of the mechanical part, which exceeds the allowable value of the motor and has nothing to do with the current. However, this phenomenon is characterized by an increase in current, or equal to or exceeding the rated current. Typically, when configuring and designing the motor, the electrical torque chosen is 10-15% greater than the mechanical shaft torque. Therefore, when the operating current of the motor reaches or slightly exceeds 85% of the rated current, it can basically be considered that the mechanical load has been reached, and when it exceeds 90%, it can be regarded as mechanical (equipment) overload.

Problem 4: The problem that occurs when the servo motor is overloaded

If protection doesn't work; The motor does not rotate, the temperature of the motor rises, and after reaching a certain temperature, this state remains unchanged.

This is how servo motors are designed. Its principle is equivalent to that of an electric mattress. When the temperature rises to a certain value, the heat dissipation is balanced, and it will not change. This is a common form of compensation.

Q5: What causes the servo overload alarm?

If the motor is operated in excess of the rated torque for an extended period of time, an overload will be reported. Generally, the load is too heavy, but when the phase sequence of the UVW is not correct or the phase sequence is not equal, an error will also be reported.

Question 6: What is the fault of servo motor overload?

Power line failures, improper parameters, and mechanical problems can all lead to overloads.

Problem 7: Servo motor overload protection

It can be adjusted by numerical control. If the load is too large, it can stop on its own.

Q8: Why is the AC synchronous servo motor overload capable?

The overload capacity is strong, on the one hand, the motor is mainly determined by the IGBT size of the servo drive.

Q9: What causes the servo motor to stop working out of control?

If the motor does not move, see if the servo amplifier alarms. If yes, find the solution through the error code. Generally, it may be an overload alarm. Try increasing the stiffness parameter.

Problem 10: The servo motor has not moved, and the servo overload alarm is caused by severe heating when it is stationary. What happened?

It should be that the servo motor begins to receive the operation instruction and starts to run, but the motor cannot operate normally, so the electrical energy to the motor is converted into heat energy and released, causing the motor to overheat.
