Support high resolution devices. Pulse input and high speed counter module product group satisfying high speed and high precision control application.
High speed counter module for counting high-speed pulse train QJ71MB91
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)"Motor series: low inertia, medium capacity.
Using a serial absolute / incremental encoder.
Rated output power: 3.5kw.
Rated speed: 3000rpm.
With the brake: without.
Shaft end: straight shaft.
Performance comparison of servo motor and stepping motor.
Stepper motor as an open-loop control system, and modern digital control technology has the essential link.
In the current domestic digital control system, stepping motor is widely used.
With the emergence of digital AC servo system, AC servo motor is more and more used in digital control system.
In order to adapt to the development trend of digital control, most of the motion control system adopts stepping motor or full digital AC servo motor as executive motor.
Although they are similar in control mode (pulse train and directional signal), there are great differences in performance and application.
The use performance of the two are compared.
