"怠速车速限制"

"怠速车速限制"是在怠速模式中设定或保持固定发动机转速所允许的最高车速。 若要进入怠速模式,必须在巡航控制接通/关闭开关位于 ON 位置上时用设定/复位开关设定发动机转速。 如果车速信号超过此数值,发动机将无法保持固定的发动机转速上。

"怠速转速限制"

"怠速转速限制"是怠速模式中的发动机最高转速。 如果利用巡航控制接通/关闭开关和设定/复位开关来设定发动机转速,出现怠速模式。 此参数的实际上限由设定的发动机转速上限所决定。 下限由设定的 "低怠速发动机转速"所决定。

将此参数设为 600 rpm 将会防止发动机以高于设定的低怠速转速的恒定转速怠速运行。

"怠速/PTO 转速变化率"

"怠速/PTO 转速变化率"能为下列功能决定发动机转速的增减速率:

  • 怠速 rpm

  • PTO rpm

参数可被设定为 5 rpm 到 1000 rpm 之间,每次增减 1 rpm。

注: 参数会同时影响怠速控制和 PTO 控制。 如果利用巡航控制接通/关闭开关和设定/复位开关来设定发动机转速,出现怠速模式。 如果利用 "PTO 打开/关闭"开关和设定/复位开关来设定发动机转速,出现 PTO 模式。

"怠速/PTO 增减转速"

"怠速/PTO 增减转速"决定了当短暂拨动加速开关或减速开关时发动机转速的增减量。 "怠速/PTO 增减转速"也适用于专用 PTO 和怠速。 如果已经设置过 "PTO 发动机设定转速","怠速/PTO 增减转速"仅适用于由巡航控制接通/关闭开关所开始的发动机转速控制。 如果已经设置过 PTO 发动机设定转速,"怠速/PTO 增减转速"也适用于由 PTO 接通/关闭开关所开始的发动机转速控制。
