Inspection/Maintenance
9.1
Inspection intervals
The amount of wear depends on many factors and may be high. Inspection intervals
must be determined and documented by the operator during startup.
9.1.1
Cleaning
Excessive dirt, dust or shavings can have a negative impact on the function of servomo-
tors; in extreme cases these factors can cause the servomotor to break down.
Therefore, you must clean the servomotors at regular intervals (after one year at the lat-
est) to ensure a sufficiently large area for heat emission.
Insufficient heat emission can have unwanted consequences. The bearing service life
is reduced through operation at impermissibly high temperatures (bearing grease de-
grades).
9.1.2
Connection cable
Check the connection cable for damage at regular intervals and replace it, if need be.
NOTE
Take the manufacturer’s data into account in the maintenance schedule.
HAZARD!
The servomotor has live parts during and after operation.
Severe or fatal injuries from electric shock!
• De-energize all power, brake and signal cables before unplugging the power or sig-
nal plug connector.
• Safeguard against accidental startup.
• Do not perform temporary repairs on the connection cables. When the cable jacket
is defective, no matter how small the fault, shut down the system immediately and
replace the cable.
