1. The general servo motor adopts incremental encoder or encoder, whose working principle is an AB phase pulse plus a Z phase pulse. AB to pulse can be understood as the two groups are independent of each other and the phase difference of 90 ° to 360 ° of grating circle is divided into 2500 grid, such as when the rotation as A leading B reached can be understood as A forward, the opposite is reversed, so when rotating produced A rising edge, A falling edge, rise along, B B drop down, that is why the servo motor described in the specifications books, 2500 lines, 10000 pulses per revolution.

The Z phase generates one pulse per cycle. So in this case you have a standard servo motor that requires 10,000 pulses per revolution.

3. We need less to control a rotation

1) Rotation direction (i.e. direction of AB phase)

2) Number of rotation cycles (i.e. number of pulses)

3)Rotation speed (i.e. pulse output frequency).

Now let's calculate the pulse frequency of high zui of servo rotation. Suppose a servomotor with 3000RPM can achieve a high speed of zui up to 5000RPM, then the large output frequency of zui we need to provide is 5000RPM*10000PLS/60S= 833.333KHz, which is beyond the large output frequency of zui of PLC which is 200KHz. In this case, the resulting electronic gear ratio (defined as the number of pulses per cycle) is described by the numerator/denominator
