1、电源电压不足:变频器的工作电压达到规定的要求,如果电压不足,变频器就无法正常工作,从而导致无法启动。
2、变频器内部组件损坏:变频器内部的电路组件如果损坏,变频器就无法正常工作,从而导致无法启动。
3、变频器设置参数不正确:变频器的参数设置不正确,可能会导致变频器无法正常工作,从而导致无法启动。
4、变频器连接线路接触不良:变频器的连接线路如果接触不良,可能会导致变频器无法正常工作,从而导致无法启动。
5、变频器控制系统故障:变频器的控制系统如果出现故障,可能会导致变频器无法正常工作,从而导致无法启动。
6、变频器外部环境温度过高:变频器的外部环境温度如果过高,可能会导致变频器无法正常工作,从而导致无法启动。
变频器的6种调速方法
变频器调速度快慢可以通过调节输入电压或频率来实现,也可以通过调节输出电压或频率来实现。
1.使用变频器键盘上下键调整变频器速度(上键加速,下键减速)
2.使用面板电位器调整速度
3.0-10V模拟量调整速度
4.0.20ma或者4-20ma调整速度
5.通过多段速指令调整速度
6.通过简易PLC调整运行及速度
