MM440负荷分配
在多电机传动中,机械耦合情况下,通常需要电机同步运行,但电机的同步并不能保证负载的平均分配,有可能会出现电机出力不均的情况,甚至一台电机被另外一台电机拖动的情况。如果电机出力不均,可能损坏负载,对于驱动器而言,很容易造成出力大的变频器报过电流故障,被反拖的变频器报过电压故障。常见的负荷平衡的解决方案有以下几种:
1. 主从控制(速度-转矩),主变频器工作在速度控制方式下,从变频器工作在转矩控制方式下其转矩给定为主变频器的实际转矩输出。
2. 主从控制(速度-速度),主变频器与从变频器工作在速度控制方式下,设置从变频器的速度略高于主变频器,使从变频器的速度达到饱和状态,用主变频器的实际输出力矩作为从变频器的转矩上限。
3. 特性软化功能,Droop功能是实现负荷分配的另一种方法,控制方法是变频器都工作在速度控制方式下,当某台电机负载过大,将其特性软化,即自动减小速度给定,力矩越大速度给定减小越多,目的是减小其出力,使各电机负荷分配均衡。参数P1492=1使能特性软化功能。
