SMW RT-5CL motor not functioning properly, seeking repair service urgently. Please respond if you can assist.

Our SMW System 30 Rotary Indexer is experiencing operational issues that have been increasingly disruptive to our production line. The unit seems to intermittently lose its ability to accurately position workpieces, resulting in misalignments that affect our machining precision. There are times when the rotary table doesn't rotate at all, stalling unexpectedly, which halts the entire manufacturing process. These problems suggest potential issues with the internal gearing or the control system, both of which are critical to the indexer's main functionalities.Given the importance of this equipment in our operations, we are evaluating both repair and replacement options. The estimated cost for replacing the unit with a new SMW System 30 Rotary Indexer is approximately $15,000, factoring in not just the price but also installation and potential downtime. However, understanding the source of these issues could guide us in deciding whether a repair might be both effective and more economically viable. Your expertise in diagnosing and repairing such problems would be greatly appreciated.
