公式トラブルシューティング手順
[Cause of error] - The position error in an active safe operating stop (SOS) is greater than the value specified in the configuration parameter CfgAxisSafety->positionRangeVmin. - If during an emergency stop the axes and spindle are decelerated, and the axes come to a stop earlier than the spindle, then the axes are standstill-monitored for the value from CfgAxisSafety->positionRangeVmin until the spindle comes to a stop. - If the protective door is closed in the automatic mode (SOM 1), axes whose drives are switched off (e g. clamped axes) are standstill-monitored for the value from CfgAxisSafety->positionRangeVmin. - After the permissive button is released, the tool magazine axis continues to move for more than 3 seconds. - During the braking test, the axis exceeds the maximum permissible path in CfgAxisSafety->positionRangeVmin. It must be assumed that a holding brake for the axis is defective! - After triggering of an SS2 stop reaction and expiration of the SS2 stopping time, a position error greater than the value in the configuration parameter CfgAxisSafety->positionRangeVmin was detected. [Error correction] - If the error occurs during the brake test, the axis remains in the servo loop. The axis has to be moved to a safe position before you switch the machine off. It must be assumed that a holding brake is defective. - Inform your service agency.
