谢谢刘工的答复。是根据实际接线、驱动器说明书的描述以及实际中需要M4/M5的位置凑上主轴(M1,ENC1),这才判断是电子齿轮模式的。说明书描述是这样的:In the electronic gear operating mode,the positioning controller calculates a new position setpoint for the motor to move to. This operating mode is used when one or several motors is follow the reference signal from a NC control unit or an encoder.而3个编码器2个驱动器之间的接线如下图,各个端口都与电子齿轮模式的接线吻合。驱动器是TLC63X系列的。
