Mitsubishi Spindle Feedback

High-precision signal transmission: It can accurately transmit the position, speed and other feedback signals from the spindle motor encoder, so that the driver can control the operation of the spindle to meet the demand for high-precision processing. For example, in precision mould processing, it can ensure that the spindle positioning accuracy is within a very small range to ensure the dimensional accuracy and surface quality of the processed mould.

Strong anti-interference ability: usually using twisted shielded wire structure, and the shielding layer is well grounded, can effectively resist external electromagnetic interference. In the industrial environment, the surrounding frequency converter, motor and other equipment generated by electromagnetic interference is strong, the anti-interference characteristics of the feedback harness can ensure the stability and accuracy of the signal, to avoid the spindle speed fluctuations or positional deviation caused by interference.

High flexibility and durability: The use of highly flexible cable materials can adapt to the frequent vibration and small displacement of the spindle motor during operation, and it is not easy for the cable to break. At the same time, it has the performance of wear-resistant, oil-resistant and corrosion-resistant, which can work stably for a long time in the harsh industrial production environment, such as in the machining workshop with oil and dust, and can maintain good electrical performance and physical properties.

Main function

Realisation of closed-loop control: The closed-loop control system is formed by feeding back the actual running status of the spindle motor to the driver. The driver adjusts the output in real time according to the feedback signal, so that the spindle speed, position and other parameters are consistent with the commanded values, improving the control accuracy and stability of the spindle, ensuring the consistency of the machining process and the stability of product quality.

Fault diagnosis and protection: When the spindle is abnormal, the signals transmitted by the feedback harness can help the control system to quickly detect the faults, such as motor overload, encoder failure, etc., and send out alarm signals in time to take corresponding protective measures to avoid equipment damage or machining accidents.

Models and specifications

Different Mitsubishi spindle motor and drive models need to be matched with the corresponding feedback harness. Common models include feedback harnesses for MDS - D - SVJ3 series drives, whose connector types and pin definitions match the encoder interfaces of these drives, as well as spindle signal cables for M70 systems, etc.45 In terms of specifications, there are a variety of choices for cable lengths, such as 1 m, 3 m, 5 m, etc., to meet the installation space requirements of different equipment.

Application Scenarios

Mainly used in CNC machine tools, machining centres and other metal processing equipment. In these equipments, high precision control of spindle is crucial to the quality of machined parts. For example, in the processing of automotive engine block, the spindle is required to control the speed and position of the tool in order to process the inner wall of the cylinder barrel with high precision; in the processing of aerospace parts, the control precision of the spindle is required to be higher, and the Mitsubishi Spindle Feedback Harness ensures the accuracy and reliability of the machining process and meets the high-precision machining needs of aerospace parts.
