SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) - - 10.2015 Edition
Values that violate the permissible value range or internal limits for
NCK machine data are supplied in a parameter from a Sinamics drive.
If several drive parameters are specified, the combination of specified
drive parameters is incorrect. In this case the result of the linking is
displayed as a value
The following causes are possible:
r0469: Resolution of the absolution position for linear absolute
encoder not valid or relationship between grid line and
measuring step not binary.
r0470: Number of valid bits of the redundant, rough position va-
lue incorrect.
r0471: Number of fine resolution bits of the redundant, rough
position value incorrect.
r0472: Number of relevant bits of the redundant, rough position
value incorrect or "0".
r0470/0471/0472: Slide factor for rough--position bits in finely resolved
actual value yields prohibited value (parameter values are
not compatible).
r0473: Number of safety--related measuring steps in position
value POS1 not valid.
r0474: A bit not recognized by the NCK is set. The alarm output
in this position can be hidden using the MD10096
$MN_SAFE_DIAGNOSIS_MASK, bit 3 = 1.
r0475: Number of the highest--value bit of the redundant coarse--
grained layer incorrect.
r0979: Error in encoder format in acc. with PROFIdrive
r9527: Encoder type not valid
Alarm display
Investigate, why in the specified drive parameter(s) an incorrect value
has been entered (e.g. for internal software errors in the drive, refer to
the drive documentation).
Switch control system OFF and ON again.
