(1) Check the circuit condition (including the connection of power supply, controller, wiring and measuring instrument, etc.), check whether the spring of the starter is flexible and whether the contact is good.
(2) When the constant voltage power supply is supplied, it needs to be started with a starter. Close the power switch, under the load of the motor, turn the starter, stay on each contact for about 2S, until the last point, the rotating arm is attracted by the electromagnet.
(3) When the motor is powered by a separate adjustable power supply, the excitation winding is energized first, and the power supply voltage is reduced to a minimum, and then the armature circuit contactor is closed, and the voltage is gradually increased to the rated value or the required speed.
(4) The motor is connected with the coupling of the production machinery first, and the rated armature voltage of less than 10% is input to determine whether the speed direction of the motor and the production machinery is consistent, and when it is consistent, it means that the wiring is correct.
(5) When the motor commutator is equipped with a tachogenerator, after the motor starts, the output characteristics of the tachogenerator should be checked, and the polarity should be consistent with the polarity of the control screen.
(6) After the motor is started, observe whether there is a spark on the commutator and whether the spark level exceeds the standard.

FAQs about Estun servo motor (1-6)
1. Will the servo motor lose steps or walk inaccurately?
The servo motor is controlled in a closed loop by the driver through the feedback of the encoder. After receiving each pulse command, the driver drives the motor to rotate at an angle, and checks whether the motor is rotated to a given point by the encoder

Estun Servo Motor - AC Servo Motor Vibration Fault Analysis
Mechanical
1. Bearing
The bearing clearance on the lead screw housing is too large after wear, or the bearing roller elements and cages are severely worn due to the lack of grease in the bearing, resulting in excessive loads. After bearing wear, the clearance is too large, which will cause the coaxiality error between the center of the motor rotor and the center of the lead screw.
