官方故障排除步驟
Parameters: %1 = Channel number %2 = Axis name, spindle number Definitions: The axis is to traverse as a ma chine axis in JOG mode using the direction keys on the machine control panel. However, this is not possible because: 1. It is already traversing as a geometry axis (through the channel-specific interface DB21-30 DBX12.6 / 12.7 (Traversing keys -/+) or DB21-30 DBX16.6 / 16.7 (Traversing keys -/+) or DB21-30 DBX20.6 / 20.7 (Traversing keys -/+)) or 2. It is already traversing as a ma chine axis (through the axis-specific interface DB31,... DBX4.7 / 4.6 (Traversing keys plus/minus)) or 3. A frame is valid for a rotated coordinate syste m, and another geometry axis involved in this is already traversing in JOG mode by means of the direction keys. Reaction: Alarm display. Remedy: Stop traversing through the channel or axis in terface or stop the other geometry axis. Program Continuation: Clear alarm with the Delete key or NC START.
