FAQ

1. What is the main function of the VW3M5102R150 power cable?
The VW3M5102R150 is a dedicated servo motor power cable designed to establish the electrical connection between a compatible servo motor and servo drive. It provides the conductors required for transferring motor power and associated connections within the servo system. With a 15-meter cable length and a preconfigured M23 connector on the motor side, it can simplify installation in industrial automation and motion-control applications. The cable is particularly useful where the servo motor and drive need to be installed at a considerable distance from each other while maintaining a suitable factory-compatible connection arrangement.

2. What conductor configuration does the VW3M5102R150 use?
The VW3M5102R150 uses a conductor configuration of 4 × 2.5 mm² + 2 × 1 mm². This configuration provides dedicated conductors for the different electrical requirements of the servo connection. The larger-section conductors are intended for the main motor power circuit, while the additional conductors support the associated electrical connections required by the compatible motor system. When replacing an existing cable, the conductor configuration should be checked carefully rather than selecting a replacement based only on cable length or connector appearance.

3. What type of connector is installed on the motor side of the VW3M5102R150?
The motor side of the VW3M5102R150 is equipped with an M23 circular industrial connector. This type of connector is commonly used in industrial motion-control applications because it provides a robust mechanical connection and supports reliable electrical contact in demanding installation environments. During installation, the connector should be fully inserted and properly secured according to the equipment requirements. The connector and cable should also be inspected for damaged contacts, contamination, deformation, or other conditions that could affect electrical continuity.

4. How should the VW3M5102R150 be installed in a servo system?
Before installation, the servo drive and motor system should be completely isolated from the power supply, and all applicable electrical safety procedures should be followed. The M23 connector should be connected securely to the corresponding motor interface, while the free-wire end should be connected to the appropriate drive terminals according to the system wiring diagram. The cable should be routed without excessive pulling, crushing, twisting, or sharp bending. It is also important to keep the motor power cable properly separated from sensitive communication and low-level signal cables where required by the installation design.

5. Why is shielding important when using the VW3M5102R150 in an industrial automation system?
The VW3M5102R150 uses a shielded cable construction to help control electromagnetic interference generated during servo motor operation. Servo drives can produce rapidly changing currents and switching signals, which may create electromagnetic noise that can affect nearby encoder, communication, sensor, or control circuits if the installation is poorly designed. Correct handling of the cable shield therefore plays an important role in maintaining electromagnetic compatibility. The shielding connection should be installed according to the servo system’s wiring requirements, and unnecessary interruptions or improper termination of the shield should be avoided.

6. What should be checked if a servo motor does not run after installing the VW3M5102R150?
The first step is to verify that the M23 motor-side connector is correctly installed and securely locked. Next, check the free-wire connection at the drive side against the applicable wiring diagram and confirm that each conductor is connected to the correct terminal. The cable should also be inspected for mechanical damage, severe bending, cuts, crushed sections, loose connections, or signs of overheating. If the wiring appears correct, electrical testing can be performed using appropriate equipment after ensuring that the system is safely isolated. The servo drive alarm history, motor status, and configuration parameters should also be checked because a motor fault is not necessarily caused by the cable itself.

7. Can the VW3M5102R150 be replaced with another servo cable having the same length?
A cable should not be selected solely because it has the same 15-meter length. Servo cables can differ in conductor cross-section, shielding construction, connector configuration, electrical characteristics, and compatibility with specific motor and drive combinations. A replacement should therefore have specifications that are appropriate for the original application. In particular, the conductor configuration, motor-side connector, drive-side termination, current requirements, shielding arrangement, and system compatibility should all be considered. Using an unsuitable replacement cable may result in connection problems, excessive voltage drop, electromagnetic interference, or unreliable servo operation.

8. What precautions should be taken when routing the VW3M5102R150?
Proper cable routing is important for maintaining both electrical reliability and mechanical service life. The cable should not be installed under excessive tension, and it should not be sharply bent or compressed by cable trays, machine covers, brackets, or other components. Where the cable is installed on moving machinery, the routing method should take the machine’s movement and the applicable cable-bending requirements into account. It is also advisable to keep the servo power cable away from sensitive signal and communication wiring when practical. Before commissioning the system, the complete cable route, connector condition, terminal connections, grounding and shielding arrangements should be inspected carefully.
