Note on the axis assignment
Note
The drives must be assigned to the axis due to the degrees of freedom that exist
for the PROFIdrive telegram configuring – also in the SI machine data.
This is the reason that the recommendations when configuring the drive
configuration also apply when configuring Safety Integrated:
S Using the standard configuration and the recommended logical basis
addresses in STEP7.
S No re–parameterization of the selected list of drive objects in drive parameter
p0978.
Under these prerequisites, the following cases can occur:
a) If the drive assignment using machine data MD 30110:
$MA_CTRLOUT_MODULE_NR, MD 30220: $MA_ENC_MODULE_NR[0/1] and
MD 13050: $MN_DRIVE_LOGIC_ADDRESS was left at the standard value, then
also the drive assignment in MD 36906: $MA_SAFE_CTRLOUT_MODULE_NR
and MD 10393: $MN_SAFE_DRIVE_LOGIC_ADDRESS must not changed.
b) If the drive assignment was changed using the machine data MD 30110:
$MA_CTRLOUT_MODULE_NR and MD 30220: $MA_ENC_MODULE_NR[0/1]
then MD 36906: $MA_SAFE_CTRLOUT_MODULE_NR should be parameterized
to the same value as for MD 30110: $MA_CTRLOUT_MODULE_NR
c) If the drive assignment was made by replacing the logical drive addresses in
MD 13050: $MN_DRIVE_LOGIC_ADDRESS, then the same marshalling should
also be made in MD 10393: $MN_SAFE_DRIVE_LOGIC_ADDRESS.
Example: Drive 1 and 2 were exchanged by interchanging index 0 and 1 of
MD 13050. MD 13050[0] was parameterized to 4140 and MD 13050[1] was
parameterized to 4100. Then, Index 0 and 1 of MD 10393 must also be
interchanged, i.e. 10393[0] must be set to 6724 and MD 10393[1] must be set
to 6700.
