High speed counter module for counting high-speed pulse train Q35DB
Can be used in combination with the external encoder for positioning and other control.
The maximum count rate can be switched, and the low frequency pulse is counted from the high speed pulse to the rising edge / falling edge.
Each 1 channel is equipped with 2 points of external uniform output.
Can be selected according to the use of "consistent output function", "continuous comparison function", to achieve high-speed control of external equipment. (QD64D2)
Provides a variety of functions, such as the same output test function (using a continuous comparison function), the default function, the latch counter function,
In order to meet the needs of various applications. (QD64D2)
The maximum count rate of the input pulse can be up to 8Mpps (differential input, 2 phase, 4 double frequency).
Can be in the semiconductor, liquid crystal manufacturing and other high position accuracy requirements of the equipment,
Perform accurate position tracking using high resolution encoders. (QD65PD2)"Drive: MR-H_ACN series built-in positioning function.
Rated output: 22KW.
In servo drive speed closed loop,
Rotor speed measurement accuracy is very important to improve the dynamic and static characteristics of the speed control loop.
In order to seek the balance between measurement precision and system cost, incremental photoelectric encoder is generally used as the speed measuring sensor,
The corresponding method is M/T velocity measurement.
Although the M/T measurement method has a certain measurement accuracy and a wide range of measurement,
But this method has its inherent defects,
Mainly includes: the measurement period must be detected at least one complete encoder pulse, limiting the minimum detectable speed.
2 control system for speed control of the timer switch is difficult to maintain synchronization,
Can not guarantee the accuracy of measurement in the situation where the speed change is larger.
Therefore, it is difficult to improve the speed tracking and control performance of servo drive by using the traditional speed loop design method.
