Cause : Topology: Actual topology contains SINUMERIK and SIMOTION components. 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.

Remedy:

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

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