Program Continuation:

Axis %1 speed setpoint limitation

%1 = Axis name, spindle number

The speed setpoint has exceeded its upper limit for a longer period than allowed.

The maximum speed setpoint is limited to a certain percentage with the axis-specific machine data 36210 CTRLOUT_LIMIT. The input value of 100% corresponds to the rated speed of the motor and hence the rapid traverse velocity (default values: 840D=110%, FM-NC=100%).

If the values are exceeded for a short time, then this is tolerated provided they do not last longer than allowed for in the axis-specific MD 36220 CTRLOUT_LIMIT_TIME. The setpoint is limited during this time to the maximum value that has been set (MD 36210). The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY (channel not ready).

-    Mode group not ready.

-    The NC switches to follow-up mode.

-    Channel not ready.

-    NC Start disable in this channel.

-    Interface signals are set.

-    Alarm display.

-    NC Stop on alarm.

-    Channel not ready.

Please inform the authorized personnel/service department. If the drive controller has been set correctly and if the machining conditions are those that normally prevail, then this alarm should not occur.

Check actual values: Local tight running of the carriage, speed dip by torque reduction due to contact with workpiece/tool, travel against fixed obstacle, etc.

Check direction of position control: Does the axis continue to rotate without control (not on 611D drives)?

Check the speed setpoint cable.

Clear alarm with the RESET key in all channels of this mode group. Restart part program.
