16 Startup, Operation, and Maintenance
16.1 Startup
The MKD motors may be put into operation only if they have been
carefully and properly mounted and if the electric connection has been
properly established.
Before putting the MKD motors into operation, the following must be
checked and/or ensured:
•
It must be possible to turn the rotor manually with the holding brake
opened; there may be no running noise (e.g. rubbing). If necessary,
the holding brake must be opened by applying a DC voltage of 24 V
±10%.
•
The motor must be mounted and aligned correctly. The motor flange
must be coupled to the machine structure or the gear absolutely
even.
•
It must be ensured that all electric connections (motor and drive
controller) have been established as specified and that the cable
screw unions have been tightened.
•
It must be ensured that the protective conductor and/or the protective
grounding have been executed properly.
•
If the optional holding brake is used, its operational reliability must be
ensured.
•
Shock protection measures against live and moving parts must be
provided for.
MKD motors may be put into operation only with drive controllers by
Rexroth. After the connection has been properly established and the
above requirements are complied with, the MKD motor can be put into
operation via the drive controller.
Note: Startup of the drives is described in the product
documentation of the particular drive controllers. Request the
corresponding product documentation from your local sales
office.
16.2 Operation
Ensure that the ambient conditions described in Chapter 13 “Application
Instructions” , are kept during operation.
