运行频率大于50Hz
若运行频率超过50Hz 除了考虑电机的振动
噪音增大外还必须确保电机轴承及机械装置的使
用速度范围务必事先查询
机械装置的润滑
减速箱及齿轮等需要润滑的机械装置在长期
低速运行时由于润滑效果变差可能会造成损坏
务必事先查询
负转矩负载
对于提升负载之类的场合常常会有负转矩发
生变频器常会产生过流或过压故障而跳闸此时
应该考虑选配适当参数的制动电阻
负载装置的机械共振点
变频器在一定的输出频率范围内可能会遇到
负载装置的机械共振点必须设置跳跃频率来避开
该共振点
频繁起停的场合
宜通过控制端子对变频器进行起停控制严禁
在变频器输入侧使用接触器等开关器件进行直接
频繁起停操作否则会造成设备损坏
接入变频器之前的电机绝缘检查
电机首次使用或长时间放置后再使用之前应
做电机绝缘检查防止因电机绕组绝缘失效而损坏
变频器测试时用1000V电压型兆欧表应保证测
得绝缘电阻5M
1.3.2 关于变频器
改善功率因数的电容或压敏器件
由于变频器输出是PWM波输出侧如安装有改
善功率因数的电容或防雷用压敏电阻等都会造成
变频器故障跳闸或器件损坏务必请拆除如图1-1
