Sinumerik Alarm 300773 Axis %1 drive %2 asynchronous mode: feedforward control structure not possible


Sinumerik Alarm 300773 Axis %1 drive %2 asynchronous mode: feedforward control structure not possible

Parameters:
%1 = NC axis number
%2 = Drive number

Definitions:
In asynchronous mode (select by MD 1465 < MD 1146) a feedforward control structure (MD 1004, bit 0 = 1) is not possible. • Modify MD 1465: $MD_SWITCH_SPEED_MSD_AM (switchover speed MSD/AM)• Modify MD 1146: $MD_MOTOR_MAX_ALLOWED_SPEED (maximum motor speed)• Modify MD 1004: $MD_CTRL_CONFIG (configuration structure) The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY (channel not ready).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:
Please inform the authorized personnel/service department. Rectify the error in the entry for the feedforward control structure MD 1004 or by deselect- ing the asynchronous mode MD 1465 > MD 1146.
• Modify MD 1004: $MD_CTRL_CONFIG (configuration structure)
• Modify MD 1465: $MD_SWITCH_SPEED_MSD_AM (switchover speed MSD/AM)
• Modify MD 1146: $MD_MOTOR_MAX_ALLOWED_SPEED (maximum motor speed)

Program Continuation:
Clear alarm with the RESET key in all channels. Restart part program.
