1. The system detects the resolution of the angular displacement of the motor, that is, the resolution;

2. The number of weekly command pulses set by the user, for example, 65536, is the requirement for the detection resolution of the angular displacement of the motor;

3, the encoder's weekly feedback detection pulse number, for example 4096, is the resolution of the system to detect the angular displacement of the motor;

4. When the resolution required by the system is the number of weekly command pulses set by the user,

Week command pulse number> encoder weekly feedback pulse number

Then the system detects the resolution of the motor angular displacement = the number of weekly feedback pulses of the encoder;

5. When the resolution required by the system is the number of weekly command pulses set by the user,

Week command pulse number < encoder feedback pulse number

Then the system detects the resolution of the motor angular displacement = the number of weekly command pulses set by the user;

6. The number of weekly pulses of the channel = the number of encoder feedback pulses × 2n = the number of encoder feedback pulses / the electronic gear ratio = the number of weekly command pulses;

7, so you use a high-resolution encoder, the actual resolution of the system may be very low, subject to user requirements or set the number of weekly instruction pulses is low;

8, so when the user requires high resolution or the set number of weekly command pulses is high, the actual resolution of the system may be very low, subject to the low number of weekly feedback pulses of the encoder;

9, for example

1) The number of weekly command pulses is 65536, and the number of encoder feedback pulses is 4096. The resolution of the system is 360°/4096.

2) The number of weekly command pulses is 4096, and the number of weekly feedback pulses of the encoder is 65536, then the resolution of the system is 360°/4096;

10, so the factor that affects the resolution of the system, ie the resolution

1) The number of weekly command pulses set by the user;

2) the number of weekly feedback pulses of the encoder;

3) The role of the electronic gear ratio is to always make the number of cycles of the channel running compatible with it!
