Inspection/maintenance
Maintenance intervals
Operating Instructions – Stainless Steel Servo Gearmotors
37
Factors that can shorten the inspection and maintenance intervals include:
• Number of real emergency stop braking operations
• Particularly high number of cycles with high motor acceleration
• Especially high cyclic duration factor at high speed
• Changing direction of rotation (reversing operation)
• Vertical mounting positions and pivoted mounting positions
• High mass moments of inertia due to the motion of the drive, e.g. in mobile drives
or drives subject to high impact and vibration load
• Application-related generative torques or torsional vibrations
• External environmental factors, such as moisture, high degree of UV exposure,
low ambient temperatures, etc.
Unit / part of
unit Time interval What to do?
Servomotor • Every 10 000 operating hours
1)
Inspect the servomotor:
• Check ball bearing.
BH.. brake
• depending on loading circumstances,
at the latest
after 3 months
Inspect the brake:
• Connect the brake to a regulated power
supply unit. Determine the opening
voltage (clicking of the brake) by in-
creasing the voltage from 10 to 24 V.
• Check the braking torque. Loop in the
brake, see chapter "Startup after stor-
age".
• Contact SEW‑EURODRIVE Service
when maintenance is required
1) The periods of wear are affected by many factors and may be shorter than the recommendation above.
