11 Operation and Maintenance
To keep a machine as safe as possible, it is necessary to perform tests regularly. Some of them can be done during
operation, others have to be done during the maintenance window. Problems detected during operation must be
evaluated if the safe operation can still be guaranteed.
11.1 Operation
During the operation different tests must be done. The following list shows what item must be checked and which action
has to be followed:
Item
Recommended test
interval
Action required
Brake Test
According to configuration
When the flag SBT Request (UPID 1A61h) becomes active, a brake test must be
performed as soon as it is possible (e.g. next finished production cycle, within the
next hour, …)
If the brake test is failed a soon maintenance must be planned.
Errors reported
Cyclically read by PLC
If the drive reports an error, it will stop and enter a safe state. The error has to be
checked and adequate measures have to be done.
Warnings reported
Cyclically read by PLC
A warning gives the possibility to react as long as full operation is still available. It is
advisable to react on warnings adequately. E.g. if a temperature warning is present,
slow down the machine or increase cooling.
