Service Repair, Maintenance And Spare Parts - Bosch Rexroth MS2E Manual

MS2E Synchronous Servomotors
If the cooling fins are partially covered with dirt,
sufficient heat dissipation via the ambient air is
no longer possible.
Insufficient heat dissipation can have undesir-
able consequences. The bearing life is reduced
by operation at inadmissibly high temperatures
(bearing grease decomposes). Overtemperature
switch-off despite operation on the basis of
selected data, because the appropriate cooling
is missing.
Clean the motor with a moist cloth to avoid elec-
trostatic charge only. Rubbing with non-conduc-
tive materials must be avoided to prevent electro-
static charges resulting in ignition hazards.
Connection cables
WARNING
Electric shock due to contact with live parts!
−
Change damaged connection cables and
decommission the plant immediately.
Do not repair any connection lines provi-
sionally.
•
Check the connection cable for damage at
regular intervals and replace it if necessary.
•
Check optionally existing drag chains on
defects.
•
Check the protective conductor connection
at regular intervals for proper condition and
tight fit and replace if necessary.

Replace motor encoder

Replace shaft sealing ring

...
The service lives of motor components, such as
seals and bearings, may vary depending on the
operating conditions, such as operation mode,
speed, vibration and shock load, and frequent
reverse mode. We recommend to change the
bearing after 30,000 operating hours. Shorter
replacement intervals may be necessary; cf.
checks during operation . We recommend reg-
ular visual inspections on shaft sealing rings.
Depending on operating conditions, signs of wear
may appear after 5,000 operating hours. If nec-
essary, replace the shaft sealing rings.
