Siemens placement machine STAR motor reports motor encoder count error and motor commutation angle is inaccurate. In fact, this is a common fault problem, but there are still many engineers who are laborious or unable to repair it. In fact, as long as the cause is found, it is relatively simple to repair, unless it is the kind that can only be solved by replacing a new STAR motor. Therefore, today I plan to share with you the root cause and solution of the STAR motor encoder count error of the Siemens placement machine.
The STAR motor reports that the motor encoder counting error and the motor commutation angle are inaccurate may be caused by the following reasons:
1. Encoder failure: The motor encoder is an important component for measuring the rotational position and speed of the motor. If the encoder is faulty, such as damaged, malfunctioning or misaligned, this can result in incorrect counts and inaccurate commutation angles. This may be caused by prolonged use, overload, vibration or electrical failure.
2. Signal interference: The counting and commutation signals of the motor encoder are affected by electromagnetic interference. Such interference may come from other electronic devices, power lines, electromagnetic fields or radiation, etc. Signal interference can cause incorrect encoder counts and inaccurate commutation angles.
3. Driver problem: The driver is a device that controls the operation of the motor. If the drive fails, such as power supply problems, unstable current, wrong drive parameter configuration, etc., it will cause encoder count errors and inaccurate commutation angles.
4. Mechanical problems: If the mechanical parts of the motor, such as shafts, gears and transmissions, are damaged, worn or loosened, it will cause the motor to run unstable, causing encoder count errors and inaccurate commutation angles.
5. Environmental problems: Dirt affects STAR and cannot return to reference. If the position of the grating disk of the STAR motor is not cleaned and maintained for a long time, a lot of dust will be adsorbed on the surface of the grating disk. Over time, dirt will accumulate on the surface of the grating disc, causing STAR to fail to return to the reference, thus reporting a motor encoder count error.
In order to solve these problems, the following measures can be taken:
1) Check the encoder: Check the working status of the motor encoder to make sure it is working properly. If a fault is found, the encoder needs to be repaired or replaced in time.
2) Eliminate signal interference: Take shielding measures, such as using shielded cables, adding filters or isolators, etc., to reduce the impact of signal interference on the encoder.
3) Check the driver: Check whether the power supply stability and parameter configuration of the driver are correct. Make sure the driver is working properly and can provide stable current and control signals.
4) Check the mechanical parts: Check if the mechanical parts of the motor are damaged, worn or loose. Repair or replace faulty parts to ensure stable motor operation.
5) Calibrate and adjust: If none of the above measures solve the problem, you can try to calibrate and adjust the motor. According to the motor model and the manufacturer's instructions, perform corresponding calibration and adjustment operations to ensure that the encoder count and commutation angle of the motor are accurate.
6) Regular maintenance and cleaning: Regularly maintain and clean the equipment and accessories, so that the equipment and accessories are in a high-quality state for operation.
If the counting error of the STAR motor encoder of the Menzi placement machine still exists, it is recommended to contact the technical maintenance team of Xinling Industrial for further help and guidance. They can provide professional advice and solutions to specific problems.
