Rexroth EcoDrive Cs Drives Motors 8-43
DOK-ECODR3-DKC**.3-CS*-PR02-EN-P
Operation
Ensure that the ambient conditions are kept during operation.
Maintenance
Cleaning
Excessive dirt, dust or shavings may affect the function of the motors
adversely, may in extreme cases even cause a failure of the motors. For
that reason, you should clean
• the cooling ribs of the motors at regular intervals, in order to obtain a
sufficiently large heat radiation surface. If the cooling ribs are dirty in
part, sufficient heat dissipation via the environmental air is not possible
any longer.
An insufficient heat radiation may have undesired consequences. The
bearing service life is reduced by operation at impermissibly high
temperatures (the bearing grease is decomposing). Switchoff caused by
overtemperature despite operation on the basis of selected data, because
the appropriate cooling is missing.
Bearings
The nominal service life of the bearings is 30.000 h, if the permissible
radial and axial forces are not exceeded. Even if the bearings are loaded
with higher forces to a minor degree only, their service life is affected
negatively.
Connection Cable
Check connection lines for damage at regular intervals and replace them,
if necessary.
Check any optionally present energy management chains (drag chains)
for defects.
DANGER
Electrocution by live parts of more than 50 V!
⇒
Do not repair any connection lines provisionally. If the
slightest defects are detected in the cable sheath,
the system must be put out of operation immediately.
Then the cable must be replaced.
Check the protective conductor connection for proper state and tight seat
at regular intervals and replace it, if necessary.
Holding brake
The check can be done by means of a function (brake check) integrated
in the firmware (see Functional Description).
