Encoder introduction

The encoder is a rotary sensor that converts the rotary displacement into a series of digital pulse signals that can be used to control the angular displacement. If the encoder is combined with the gear train or screwdriver, the linear displacement can be measured.

According to the output signal, the encoder can be divided into differential and collector.

EN630 is applicable to collector incremental encoder, no need to add a separate PG card.​

Encoder line number: refers to a circle line of photoelectric encoder, such as 1024 lines, 2048 lines.​

Encoder resolution: the smallest recognizable angle of encoder in the normal work, such as 2500 lines incremental encoders, combined with A / B phase quadruple, we can calculate the resolution is (360 °/ 100000) degrees

Motor self – learning parameters

F15.01Asynchronous motor rated powerBase on motor type
F15.02Asynchronous motor rated voltageBase on motor type
F15.03Asynchronous motor rated currentBase on motor type
F15.04   Asynchronous motor rated frequencyBase on motor type
F15.05 Asynchronous motor rated rotational speedBase on motor type
F15.06Asynchronous motor poles No.Base on motor type

 

Remarks

1. If motor is overcurrent or overload and the motor rotation is weak when start the motor, the encoder AB phase sequence reverse, choose one of the following ways to correct:

Modify the F16.02 value (F16.02 = 00 for the positive phase sequence, F16.02 = 01 for the reverse phase sequence)​

Exchange A, B phase wiring

​Exchange any two phases motor output line

2. Motor parameter self-tuning selection. For this function, set F15.19 = 2 (asynchronous motor rotate no-load to self-adjusting)would be better, this method can intelligently adjust the AB phase sequence F16.02 value.​

3. Set other parameters according to the actual application.
