具有反电势控制的无测速机系统反电势控制不需要测速装置,只需测量 SIMOREG 的输出电压,测出的电枢电压经电机内阻压降补偿处理(I×R -补偿)。补偿量的大小电流调节器优化过程中自动确定,这种调节方式的精度与电枢回路中电阻的温度系数有关,约为 5 %。建议,为了达到高的精度,在电机处于热状态时,要重复进行电流调节器优化过程。当对精度要求不高且不能安装测速装置及电机仅工作在基速以下时,可采用反电势控制方式。注意:在这种工作方式时,不能实现 EMF-弱磁控制。自由选择转速实际值信号在这种工作方式下可任选一个连接器编号作为转速实际值信号,当转速实际值传感器由工艺附加板实现时,该方式为方案。转速实际值在送到转速调节器之前,可通过参数设定的滤波电路PT1-滤波器)和两个可设定的带
