、请说明变频器的保护功能?
保护功能可分为以下两类：
（1）检知异常状态后自动地进行修正动作，如过电流失速防止，再生过电压失速防止。
（2）检知异常后***电力半导体器件PWM控制信号，使电机自动停车。
如过电流切断、再生过电压切断、半导体冷却风扇过热和瞬时停电保护等。
、为什么用离合器连接负载时，变频器的保护功能就动作？
用离合器连接负载时，在连接的瞬间，电机从空载状态向转差率大的区域急剧变化，
流过的大电流导致变频器过电流跳闸，不能运转。
、在同一工厂内大型电机一起动，运转中变频器就停止，这是为什么？
电机起动时将流过和容量相对应的起动电流，电机定子侧的变压器产生电压降，
电机容量大时此压降影响也大，连接在同一变压器上的变频器将做出欠压或瞬停的判断，
因而有时保护功能（IPE）动作，造成停止运转。
、什么是变频分辨率？有什么意义？
对于数字控制的变频器，即使频率指令为模拟信号，输出频率也是有级给定。
这个级差的.小单位就称为变频分辨率。
变频分辨率通常取值为0.015~0.5Hz.例如，分辨率为0.5Hz，
那么23Hz的上面可变为23.5、24.0 Hz，因此电机的动作也是有级的跟随。
这样对于像连续卷取控制的用途就造成问题。
在这种情况下，如果分辨率为0.015Hz左右，对于4级电机1个级差为1r/min 以下，
也可充分适应。另外，有的机种给定分辨率与输出分辨率不相同。
、装设变频器时安装方向是否有限制。
变频器内部和背面的结构考虑了冷却效果的，上下的关系对通风也是重要的，
因此，对于单元型在盘内、挂在墙上的都取纵向位，尽可能垂直安装。
