Mode group ('BAG') not ready for operation
Channel not ready for operation.
NC Start inhibited.
NC Stop at alarm.
The NC changes to follow-up mode.
Alarm display.
Interface signals are set.
Correct setting of the drive controller and normal machining conditions pro-
vided, this alarm should not occur.
•
Check actual values: local heavy running of carriage, speed dip and
torque peak in case of workpiece/tool contact, traversing to a fixed obsta-
cle, etc.
•
Check direction of position control: Does the axis move uncontrolled?
•
Check speed setpoint cable.
•
Reduce axis speed or increase MD 32 260 RATED_VELO.
The stepping-switch motor axes must be re-referenced. Press the RESET key to
clear the alarm.
Axis %1 drift limit exceeded
%1 = Axis name, spindle number
For analog drives only!
The permissible maximum value of the drift (internal drift value integrated to
the automatic drift compensation) has been exceeded during compensation!
The permissible maximum value is defined in the axis-specific MD 36 710
DRIFT_LIMIT. The drift value itself is not limited.
Automatic drift compensation: MD 36 700 DRIFT_ENABLE = 1
The deviation of the actual position to the set position (drift) is automatically
checked cyclically in IPO clock and automatically compensated to zero by
slowly integrating an internal drift value.
Manual drift compensation: MD 36 700 DRIFT_ENABLE = 0
A static offset can be added to the speed setpoint in MD 36 720
DRIFT_VALUE. It will not be included in the speed monitoring, since it acts
as a voltage zero offset.
Alarm display.
Readjust drift compensation with automatic drift compensation on the drive
switched off until the following error is approximately zero. Then reactivate
automatic drift compensation to compensate dynamic drift changes (heating).
Press the Clear key to clear the alarm. No further operation required.
