Sinumerik Alarm 300507 Axis %1 drive %2 synchronization error of rotor position
Parameters:
%1 = NC axis number
%2 = Drive number
Definitions:
There is a difference of more than 45° electrical between the present rotor position (C/D track) and the new rotor position as determined by fine synchronization. Faults may have occurred in the encoder or zero marker signals. The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY (channel not ready).
Reactions:
– Mode group not ready.
– Channel not ready.
– Channel not ready.
– NC Start disable in this channel.
– NC Stop on alarm.
– The NC switches to follow-up mode.
– Alarm display.
– Interface signals are set.
Remedy:
• Use original Siemens encoder cables (they have a higher degree of screening).
• Check the encoder, encoder cables and screen connection for damage.
• Check the shield connection on the front plate of the controller module (top screw).
• Replace the control module.
• Check MD 1016 $MD_COMMUTATION_ANGLE_OFFSET (commutation angle offset).
Program Continuation:
Switch control OFF – ON.
