Cause : Actual topology contains SINUMERIK and SIMOTION components comes when the detected actual topology contains SINUMERIK and SIMOTION components. The drive system is no longer booted. In this state, the drive control (closed-loop) cannot be enabled.

Alarm value (r2124, interpret hexadecimal):

ddccbbaa hex: cc = fault cause, bb = component class of the actual topology, aa = component number of the component

cc = 01 hex = 1 dec:
An NX10 or NX15 was connected to a SIMOTION control.

cc = 02 hex = 2 dec:
A CX32 was connected to a SINUMERIK control.

Re alarm value = 1: Replace all NX10 or NX15 by a CX32.

Re alarm value = 2: Replace all CX32 by an NX10 or NX15.
