The drive is getting hotter than usual – is this still normal?

Correctly assess warning signs

No matter how high-quality or precisely a product is manufactured, errors can still occur during operation. Depending on the issue, a simple re-lubrication may be sufficient, or in the case of serious deviations, continued operation could lead to complete product failure. In this topic group, you will find information on potential fault symptoms, their causes, and possible corrective measures.

FAQs

A block drive describes the execution of the lift against a fixed stop. In this process, the lifting element is 'blocked' by the fixed counterpart.

Mechanical drives are very sensitive to movement against fixed stops. Depending on the force of the motor, a block drive typically results in damage to the spindle-nut system.

Overheating, unusual noises, or a noticeable decrease in performance can be signs of insufficient lubrication. Pay attention to these symptoms for timely maintenance.

Inspect moving parts for signs of wear and increasing play. If wear is detected, consideration should be given to inspection or replacement.

Yes, the maintenance and operating manual provides valuable guidance on the procedure. You can find the documentation here.

Is the motor correctly wired and the brake releasing? Do you have sufficient lubricant on the spindle? Are the drives installed without tension? If so, you've already eliminated the most common sources of malfunction. If the issue persists, please call us at +49 7261/9263-0.

The environment can affect maintenance intervals. High levels of dust or humidity may require shorter maintenance intervals. Regularly check the environmental conditions and adjust the maintenance schedules accordingly.

Check the power supply, brake wiring, and the condition of the control unit. If necessary, contact our customer support. Also, ensure proper wiring of the limit switch. Most blockages occur during setup operations.

Check for dirt or worn-out parts. Thorough cleaning and, if necessary, replacement of damaged components may solve the problem. If the Linear Chain is noisy after acquisition, system tensions could be responsible.

Check the connection to the control system and the programming. Ensure all safety precautions are accounted for.

Check the power supply. For 24V DC drives, fluctuating loads can also cause varying speeds. Additionally, ensure that potentiometers, encoders, and brakes are correctly controlled.

A thorough familiarization with the operating manual is advisable. However, in case of uncertainty or complex maintenance tasks, specialized personnel should be consulted. You can reach us anytime at +49 7261/9263-0.
