MDX61B0005-5A3-4-0T在伺服驱动器速度闭环中，电机转子实时速度测量精度对于改善速度环的转速控制动静态特性至关重要。
MDX61B0005-5A3-4-0T为寻求测量精度与系统成本的平衡，一般采用增量式光电编码器作为测速传感器，与其对应的常用测速方法为M/T测速法。
MDX61B0005-5A3-4-0TM/T测速法虽然具有一定的测量精度和较宽的测量范围，但这种方法有其固有的缺陷，主要包括：1）测速周期内必须检测到至少一个完整的码盘脉冲，限制了最低可测转速；2）用于测速的2个控制系统定时器开关难以严格保持同步，在速度变化较大的测量场合中无法保证测速精度。
MDX61B0005-5A3-4-0T因此应用该测速法的传统速度环设计方案难以提高伺服驱动器速度跟随与控制性能 。
MDX61B0005-5A3-4-0T In the servo drive speed closed loop, the real-time speed measurement accuracy of the motor rotor is crucial to improving the dynamic and static characteristics of the speed control of the speed loop.
MDX61B0005-5A3-4-0T In order to seek a balance between measurement accuracy and system cost, incremental photoelectric encoders are generally used as speed measurement sensors, and the corresponding commonly used speed measurement method is the M/T speed measurement method.
MDX61B0005-5A3-4-0T Although the M/T speed measurement method has certain measurement accuracy and a wide measurement range, this method has its inherent flaws, which mainly include: 1) At least one complete code disk pulse must be detected within the speed measurement cycle, which limits the minimum Rotation speed can be measured; 2) The two control system timer switches used for speed measurement are difficult to maintain strict synchronization, and speed measurement accuracy cannot be guaranteed in measurement situations with large speed changes.
MDX61B0005-5A3-4-0TTherefore, the traditional speed loop design using this speed measurement method is difficult to improve the speed following and control performance of the servo drive.
