Axis %1, drive %2 zero mark monitoring motor measuring system
%1 = NC axis number
%2 = drive number
Error in modulo (16/10) incrementation of encoder mark number on zero marker
crossings. Increments have been lost or extra increments trapped.
The alarm can be reconfigured using MD 11412:
ALARM_REACTION_CHAN_NOREADY (channel not ready).
Mode group not ready.
Under certain circumstances it can be switched over across the entire channel
via MD.
Channel not ready.

Please inform the authorized personnel/service department. Use original
Siemens pre-assembled encoder cables (high degree of shield protection).
Check encoder, encoder cable for cable break and shield bonding point. Check
shielding surface on front panel (top screw), replace closed-loop control mod-
ule. Check distance between gear wheel and sensor on gear wheel encoders. If
a BERO is installed, it is not the BERO signal which is monitored, but the zero
marker of the encoder.
Switch control system OFF and ON again.
