9.6 Replacing a motor or encoder

9.6 Replacing a motor or encoder
Warning
!
After hardware and/or software components have been changed or replaced, it is
only permissible to boot the system and activate the drives when the protective
devices are closed. Personnel shall not be present within the danger zone.
Depending on the change or replacement, it may be necessary to carry out a new,
partial or complete acceptance test (see Chapter 9.5 Acceptance test).
Before persons may re--enter the hazardous area, the drives should be tested to
ensure that they exhibit stable behavior by briefly moving them in both the plus
and minus directions (+/--).
It is especially important to carefully observe this for high--dynamic linear and
torque motors.
Warning
!
After the measuring system has been replaced -- regardless of whether it is a
direct or an indirect system -- the relevant axis must be re--calibrated.
Note
After SI relevant hardware has been replaced, this must be acknowledged using
softkey "Acknowledge SI HW" The procedure is logged in file
"Confirm_SI_HW.log" -- and is saved in the HMI file system
under.../user/sinumerikhmidatasafety.
Example for the structure and content of Confirm_SI_HW.log:

Description
The following information essentially refers to replacing a motor encoder. The
limitations that apply as well as the procedures are essentially the same when
replacing a direct measuring system.
