代码 25070: Axis %1 drift value too large

Parameters: %1 = Axis name, spindle number Definitions: Only with analog drives! The permissible maximum value of drift (internal, integrated drift value of automatic drift compensation) was exceeded during the last compensation operation. The permissible maximum value is defined in the axis-specific MD36710 $MA_DRIFT_LIM IT. The drift value itself is not limited. Automatic drift compensation: MD36700 $MA_DRIFT_ENABLE=1 The difference between actual and set point position (drift) is checked cyclically in the IPO cycle when the axes are at zero speed. The difference is automa tically compensated to zero by slowly integrating an internal drift value. Drift compensation by hand: MD36700 $MA_DRIFT_ENABLE=0 A static offset can be added to the speed setpoint in the MD36720 $MA_DRIFT_VALUE. This is not included in the drift monitoring because it acts like a voltage zero offset. Reaction: Alarm display. Remedy: Please inform the authorized personnel/service departm ent. Adjust the drift compensation with the automatic drift compensation switched off at the driv e until the position lag is approximately zero. Then reactivate the automatic drift compensation in orde r to balance out the dynamic drift changes (effects of heating up). Program Continuation: Clear alarm with the Delete key or NC START.
