Sinumerik Alarm 300510 Axis %1 drive %2 error on actual current measurement zero balancing
Parameters:
%1 = NC axis number
%2 = Drive number
Definitions:
The value of the actual current exceeded the maximum permissible limits during current zero balancing (performed on every pulse disable). For example, the synchronous motor is rotating at a small intermediate circuit voltage and current is flowing across the free- wheeling diodes in the intermediate circuit.
Reactions:
– NC not ready.
– Channel not ready.
– Channel not ready.
– NC Stop on alarm.
– NC Start disable in this channel.
– The NC switches to follow-up mode.
– Alarm display.
– Interface signals are set.
Remedy:
• Error in actual current measurement (if necessary, replace 611D power section or controller module)
• Incorrect power section module (1/2 axis)
• Check the contact between the controller module and the power section
• Check the contact between the fixing screw and the controller module
Program Continuation:
Switch control OFF – ON.
