15 Commissioning, Operation and Maintenance
15.1 Commissioning
Proper, careful assembly and a proper electrical connection are required
for commissioning.
Before MKE motors are commissioned, the following must be
checked/ensured:
· It must be possible to turn the runner manually when the brake is
released; running noises (e.g. scraping) must not exist. If necessary,
the brake must be opened by applying a 24V ±10% direct current.
· The motor must be properly assembled and aligned. The attachment
of the motor flange to the machine construction / transmission must be
according to the plan.
· Ensure that all electrical connections (motor and drive control device)
are made according to regulations and that the screwed connections
are tight.
· Ensure that the grounded conductor / protection ground is properly
executed.
· Ensure that any optionally existing brake functions safely.
· Measures for protection against accidental contact must exist for parts
that are under power or that move.
Commissioning of MKE motors is permitted only with Rexroth Indramat
drive control devices. After proper connection and maintenance of the
requirements mentioned above, the drive control device of the MKE motor
can be put into operation.
Note: Commissioning of the drives is described in the corresponding
product documentation of the drive control devices. Request
the corresponding product documentation from the
responsible sales branch.
15.2 Operation
During operation, make sure that the ambient conditions described in Ch.
12 “Notes Regarding Application” are maintained.
15.3 Maintenance
Cleaning
Excess dirt, dust or filings can negatively influence the functioning of the
motors; in extreme cases, the motors may break down. Therefore, you
should maintain the motor regularly as follows:
· Clean the radiator fins of the motors in order to obtain a sufficiently
large heat dissipation surface. If some of the radiator fins are covered
by dirt, heat dissipation using the ambient air is no longer sufficient.
Insufficient heat dissipation can have undesired results. The bearing
durability is decreased due to operation at unacceptably high
temperatures (bearing lubrication decomposes). This can lead to
switching off due to excess temperature, despite operation according to
the selection data, because the corresponding cooler is missing.
