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).
Battery
Motors with absolute encoders need a battery to back-up the encoder
signals. The battery is set into the drive controller (Exception: Rexroth
Cartesian Motion Systems (CMS)).
The drive controller observes voltage of battery and gives just in time a
warning “F248 Low battery voltage".
The service life of the battery depends on the ratio of switch-ON-duration
to switch-OFF-duration:

Thus, the longer the drive controller is switched on, the longer is the
service life of the battery.
