Sinumerik Alarm 20052 Channel %1 axis %2 already active
Parameters:
%1 = Channel number
%2 = Axis name, spindle number
Definitions:
The axis is to traverse as machine axis in JOG mode via the jog keys on the machine control panel. However, this is not possible because: 1. It is already traversing as geometry axis (through the channel-specific interface DB 21 – 28, DBX 12.6, DBX 12.7, DBX 16.6, DBX 16.7 or DBX 20.6 and DBX 20.7) or 2. it is already traversing as machine axis (through the axis-specific interface DB 31 – 48, DBX 4.6 and DBX 4.7) or 3. a frame is valid for a rotated coordinate system and another geometry axis involved in this is already traversing in JOG mode by means of the direction keys.
Reactions:
– Alarm display.
Remedy:
Stop traversing through the channel or axis interface or stop the other geometry axis.
Program Continuation:
Clear alarm with the Delete key or NC START.
