Change of rotary encoder steps and matters needing attention
When the rotary encoder using malfunction and wear for a long time, affect the normal use, we should consider to change the rotary encoder, in the process of replace the encoder, should be in strict accordance with the instructions on the use of the encoder is used to install the first, the rotary encoder says below replacement steps and replace the rotary encoder considerations, use of rotary encoder.
Replacement of rotary encoder reference the following steps: 1: the back cover and breaking-out motor encoder back cover;
2: loosen the encoder mounting screws;
3: rotate the rotor shaft of the motor, make the signs on the rotor of the rotary encoder and its shell logo overlap;
4: remove the rotary encoder, then need to pay special attention to at the time of loading and unloading use special screw cap out as far as possible, lest damage encoder;
5: the new encoder rotation, make the two symbols of encoder;
More than 6: according to the reverse order to install encoder.
A rotary encoder notice: 1.
In the process of installing encoder, make sure the rotor of the motor, otherwise you will lose the relative position of the rotor.
If lost relative position, the old motor you need to use an oscilloscope to adjust the installation position of the encoder, the new motor can be judged according to the sign on the motor rotor shaft to adjust the installation position of rotary encoder, either mechanical adjustment, also can adjust the drive parameters to set an offset value.
Should pay attention to when in rotary encoder, encoder installed after fixed screw, must be the top wire on the coupling is loose after remove the assembly stress, resistance phenomenon, after rotating flexible hands in top silk top to death.
Need to pay attention to the connection order encoder, anti may run over current fault.
Rotary encoder using standard conversion effect of rotary encoder is very fast, but want to keep such good performance, in daily use process need to develop correct and reasonable operation method, take a look at below use of rotary encoder.
, installation need to be careful, to avoid the impact of the rotary encoder used as connection with other mechanical equipment, to use flexible connector, when connected during the installation process to avoid encoder accidentally injured by hard objects, most of the time it is hard to on the face of such bumps, use soft connector can during the installation process will not cause negative pressure to the encoder.
Second, reduce vibration, prevent no pulse rotation occurs if there is a pulse coder, will seriously affect the conversion rate of the equipment.
Equipment connection is not correct, equipment operation mode is not reasonable, quality is not good enough, the influence of the working environment and so on will cause the encoder pulse.
So when installation check whether the connection is loose, should be more strengthened operating mode is correct, a specification equipment installation, lower vibration frequency to prevent no pulse.
Three improper wiring, wiring and connections is also in use process will affect the rotary encoder error, not only such, also can cause a serious internal encoder circuit, even line was burn out.
So close when it's in the connection line in the encoder, the output of the input power cord should be carried out in accordance with the corresponding color reasonable collocation, high tension line and the connection between the power lines to separate operation.
Shanghai electronic products is 27 years old, encoder manufacturers, specializing in the production of various types of rotary encoder, electronic research and development production of magnetoelectric encoder is magnetoelectric rotary encoder, according to the needs of customers to make incremental encoder or absolute encoder.
Price higher than that of photoelectric encoder, magnetoelectric encoder is widely used in robot, automatic production lines, automatic assembly machine, elevator, textile machinery, sewing machinery, packaging and printing machinery, CNC machine tools, mapper and Angle measuring instrument, etc.
Magnetoelectric encoder also can be in PLC application as the high speed signal input element, make PLC more quickly and accurately implement the closed-loop control.
Looking for a rotary encoder manufacturer is looking for electronic.
