F644 Negative Travel Limit Switch Detected檢測到負行程限位開關(guān)

The negative travel limit switch has been actuated. 負行程限位開關(guān)已啟動。

The axis has been stopped with the error reaction "set velocity command value to zero". 軸已停止，錯誤反應為“將速度命令值設(shè)置為零"。
Bit 2 of P-0-0090, Travel limit parameter has been set to "Exceeding the
travel limit is considered as an error", or a drive control command has
been started while the axis limit value is exceeded (e.g. drive-controlled
homing).P-0-0090的第2位，行程限制參數(shù)已設(shè)置為“超過行程限制被視為錯誤"，或者驅(qū)動控制命令在超過軸極限值時啟動（例如驅(qū)動控制歸位）。

Cause:原因：
The negative travel limit switch has been actuated.
負行程限位開關(guān)已啟動。

Remedial action:補救措施：
1. Reset the error
重置錯誤
2. Activate the power supply
激活電源
3. Move the axis into the permissible working range
將軸移動到允許的工作范圍內(nèi)

Note:The drive will not accept any command values that lead further
away from the permissible range.
注意：驅(qū)動器將不接受任何進一步導致錯誤的命令值遠離允許范圍。
Specifying such a command will again result in this error.
這樣的命令將再次導致此錯誤。
