515-2AM02-0AB0可编程模块
需要控制的电机及变频器自身
1)电机的极数。一般电机极数以不多于(极为宜,否则变频器容量就要适当加大。
2)转矩特性、临界转矩、加速转矩。在同等电机功率情况下,相对于高过载转矩模式,变频器规格可以降额选取。3)电磁兼容性。为减少主电源干扰,使用时可在中间电路或变频器输入电路中增加电抗器,或安装前置隔离变压器。一般当电机与变频器距离超过50m时,应在它们中间串入电抗器、滤波器或采用屏蔽防护电缆
515-2AM02-0AB0可编程模块
1、控制定子磁链引入定子磁链观测器,实现无速度传感器方式;
2、自动识别(ID)依靠的电机数学模型,对电机参数自动识别;
3、算出实际值对应定子阻抗、互感、磁饱和因素、惯量等算出实际的转矩、定子磁链、转子速度进行实时控制;
4、实现Band—Band控制按磁链和转矩的Band—Band控制产生PWM信号,对逆变器开关状态进行控制。
矩阵式交—交变频具有快速的转矩响应(<2ms),很高的速度精度(±2%,无PG反馈),高转矩精度(<+3%);同时还具有较高的起动转矩及高转矩精度,尤其在低速时(包括0速度时),可输出150%~200%转矩。
