Motor Types
Functional Safety with SMU can be used for all
LINAX®, ELAX® and ROTAX® motor families, as well as
rotary brushless motors with different A/B/Z encoder
signals. Rotary brush type DC motors are not subject
to the functional safety.

compensation must be used for safety functions SS2
and SLS. The safety function SBC (Safe Break Control)
is not available.
Note2: Rotative motors operating suspended loads
are excluded from SS2 and SLS safety functions.
Commissioning
The configuration assessment has to be warranted by
the client for each modification of the functional
safety and its parameters through commissioning.
Period of use
The maximum period of use for operating with
functional safety with SMU is 20 years.
Continuous operation
The XENAX® servo controller must be switched off at
least once a year.
Wiring
The length of the connection cables must not exceed
