Maintenance Intervals
Diligent regular inspections and maintenance help to detect malfunctions early and remedy them before consequential damage occurs. If malfunctions, unusual loads or conditions occur that might negatively affect the drive system, e.g. overload, short circuit or mechanical damage, the components of the drive system have to be checked immediately.
The intervals for maintenance tasks are very dependent on the local conditions at the location where the drive system is in use, e.g. dirt, load, how frequently it is switched on, etc.
The following table gives a general overview of the maintenance measures and intervals. The measures and the specified intervals have to be adapted to the respective conditions and supplemented as necessary.
|
Measures |
Maintenance interval |
|---|---|
|
Cleaning the surfaces |
Directly dependent on the degree of soiling; heavy soiling interferes with the proper heat dissipation of the components. |
|
Visual inspections, e.g. of the housing, cable, connections, leaks |
|
|
Exchanging the bearings |
If the motor is run with the rated data, we recommend exchanging the bearings after 40,000 operating hours. If the bearing is subjected to axial and radial forces, the service life is reduced as shown by the characteristic curve on the motor data sheet. In vertical installation position, the grease service life stated in the data sheet is reduced by half. |
|
Relubrication intervals |
You can find a reference value for the relubrication intervals of the axial bearings on the motor/motor data sheet. The relubrication intervals heavily depend on the motion profile actually traversed and the cycle times. The B-side bearing is lubricated for life and needs no maintenance. |
|
Replacing the encoder belt, if applicable |
20,000 h |
|
Lubrication change, performed by AMK |
If motors were in storage for more than 2 years, we recommend a lubrication change. |
Regularly check connection cables for damage, and replace if required. Do not make provisional repairs to the connection lines. If any damage is visible on the sheathing, no matter how small, immediately shut down the system and renew the cables.
