Note!
If integrated safety is not to be used for an axis, the safe inputs SIA and SIB of
the axis must be fixedly assigned with "HIGH" potential (24 V).
The wiring should not give the impression of connected safety sensors, or
should be provided with adequate labelling.
)
Note!
Earth the motor separately (see basic circuit diagram).
Earthing only via the motor cable does not provide sufficient protection
because the mains fuse does not protect the motor cable.
ƒ In the drive system, the supply feeder is usually designed more strongly
than the motor cables. Therefore, in the event of an error (e.g. earth fault),
the mains fuse is able to protect the motor cable and thus also the PE in the
motor cable.
