8.1 Important notes
Danger!
Hazardous voltage on the power connections even when disconnected
from mains: residual voltage >60 V!
Before working on the power connections, always disconnect the drive
component from the mains and wait until the motor is at standstill.
Verify safe isolation from supply!
Shaft sealing rings and roller bearings have a limited service life.
Regrease bearings with relubricating devices while the low−voltage machine is running.
Only use the grease recommended by the manufacturer.
If the grease drain holes are sealed with a plug, (IP54 drive end; IP23 drive and nondrive
end), remove plug before commissioning. Seal bore holes with grease.
8.2 Maintenance intervals
Inspections
¯ If the machine is exposed to dirt, clean the air channels regularly.
8.2.1 Motor
¯ Only the bearings and shaft sealing rings become worn.
– Check bearings for noise (after approx. 15,000 h at the latest).
¯ In order to prevent overheating, remove dirt deposits on the drives regularly.
¯ We recommend carrying out an inspection after the first 50 operating hours. In
this way, you can detect and correct any irregularities or faults at an early stage.
8.2.2 Encoder
The guarantor of the engine is a component for use with security features.
Danger!
If not properly performed work on the guarantor of the motor lead to the loss of safety
functions.
Possible consequence: Property damage and / or personal injury.
Protection measure: Repair or replacement of the collateral provider is allowed only by
Lenze Service or its empower people.
After a service life of 10 years, an inspection of the metal elastomer torque plate is
required for the AS1024−8V−K, AS1024−8V−K2; AM1024−8V−K, and AM1024−8V−K2
encoders. If no replacement is required, an inspection interval of max. 5 years has to be
observed.
