NC stop for alarm

Correctly set the PROFIsafe address of the drives.

Program con‐

Switch control system OFF and ON again.

Axis %1 value %2 in drive parameter %3 violates the limits of NCK MD %4

%1 = axis name, spindle number

%2 = value in the drive parameter

%3 = number of the drive parameter, e.g. r0979

%4 = name of the NCK machine data

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:

Resolution of the absolution position for linear absolute encoder not valid or relationship between grid division

and measuring step not binary.

Number of valid bits of the redundant, rough position value incorrect.

Number of fine resolution bits of the redundant, rough position value incorrect.

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).

Number of safety-related measuring steps in position value POS1 not valid.

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.

Number of the highest-value bit of the redundant coarse-grained layer incorrect.

Error in encoder format in acc. with PROFIdrive

Encoder type not valid
