SetConfiguredAxesCount
配置模擬軸的數量。模擬軸的數量取決於有多少給定值超過實際的硬體數量,若給定值大於實際軸的數量,KINGSTAR 會顯示所有實際軸與模擬軸。例如,有五個實際軸而給定值為七,則會顯示五個實際軸及兩個模擬軸;若給定值小於或等於實際軸的數量,KINGSTAR 會顯示所有實際軸的數量,而無模擬軸。
語法
KsError SetConfiguredAxesCount(
int Count
);
參數
Count:模擬軸的數量,最大值為 256。
回傳值
如果此函式執行成功,會回傳 errNoError
,否則會傳回錯誤碼。如需更多有關錯誤碼的資訊,請參閱 KsError 清單。
備註
允許工程師在未取得所有硬體狀態下測試應用程式。模擬軸需在用 ConfigureAxis 配置前使用 SetConfiguredAxesCount 創建,此函式必須在 Create 後及 Start 前呼叫,一旦連結建立,模擬軸即無法修改。
