Compatibility of SM301/SM300
The SM301 safety module is compatible with the SM300. The controller needs to be
adapted since the safe parameter set is required. Observe the following:
ƒ The GSE file can be used.
ƒ The PROFIsafe bits that are not used with SM300 must be suppressed in the SM301,
since unset bits would activate safety functions.
ƒ Speed−dependent functions cannot be used.
Compatibility of different SM301 versions
Replacement of an SM301 by an SM301 with a higher firmware version (SW):
ƒ Every SM301 can be used with a safe parameter set of an elder firmware version
without any changes.
ƒ The safe parameter set including CRC in the memory module of the drive is not
changed when the parameter set from the memory module is accepted.
ƒ The CE Declaration of Conformity remains valid.
ƒ The replacement of the safety module by an equivalent module is ensured. Thus,
there is no need for spare part stockage of SM301 safety modules with elder
firmware versions.
ƒ Safe parameter sets of the "SM301 safety module" component can be loaded into
an SM301 with a higher firmware version without any changes.
– Extended functionalities of the newer firmware version cannot be selected and
executed.
The safe parameter set of an SM301 with a newer firmware version cannot be loaded into
an SM301 with an elder firmware version.
1.2.3.2 Safety category
The implemented safety functions meet the requirements of the standards:
ƒ Control category 3 according to EN ISO 13849−1
In order to comply with category 3, the external wiring and cable monitoring must also
meet the requirements of category 3.
ƒ Performance Level (PL) "e" according to EN ISO 13849−1
