How to replace the current encoder by Roundss brand?！

Replace imports encoder (a) incremental encoder, absolute encoder

Many useful for domestic users import encoder (encoder), which imports some encoders come in with equipment imports, need spare parts to maintain, as some equipment manufacturers to develop generic, need to find the same function encoder, some owners or institute to ensure the application of reliability specified. However, imports encoder generally expensive, long lead times, import manufacturers arrogant service is not in place, and the future long-term stable supply is not guaranteed and can not repair or maintenance of higher costs and other issues. In practical applications, due to the long lead times imports encoder or service is not in place, resulting in improper selection, delivery or acceptance delay, the pipeline nearly discontinued story often occur. In fact, including the Shanghai Jing Pu encoder Electrical Company and other domestic manufacturers have the introduction of foreign technology, development and production of encoders, we can already replace most imported encoders, including the brand or brands in Europe, Japan and Korea, for example, the incremental value encoders, absolute encoders, including the absolute multi-turn encoder, domestic users may wish to try to replace imports encoder, here we come to discuss how to be replaced.

First, replace imports encoder to have three basic concepts:
one. Fairly functional application replacement
two. Reliability performance guarantee
three. Professional and accurate service

First Laijiangjiang (a) The functional equivalent replacement application

There are five basic functional requirements:

one. Resolution quite, said before importing incremental encoders generally have "-500", "- 512", "- 600", "- 1000", "- 1024", "--2048" and other resolutions, in particular most of Europe's drive with 1024 lines, can generally be replaced; and some of the higher resolution, there is some difficulty; and the absolute value of a single-turn encoder 17 or less, such as "8" "10" "12" " 13 "" 16 "" bit "and so on, Shanghai Jing Pu can provide electrical and mechanical replacement, there are more than Gray code" 180 "" 360 "lines, we can also replace; absolute multi-turn encoder 1212, 1213, ( or 24bit, 25bit, XXX425) and so on, Shanghai Jing Pu mechanical and electrical company's products can replace most, and Shanghai Jing Pu Electrical company of GA, GM series encoders also have some internal smart feature that automatically adapt to the 12 and 13 , 24 and 25, such as a 13-bit encoder may also apply to 12-bit, 25 (1213) multi-ring can be simultaneously applied to 24 (1212) replacement.

two. Operating voltage, the encoder on the import of most tags can see "Power: xx V", as long as in the replacement and clearer Make no mistake, the wrong may not work well, perhaps burned parts, so still pretty important.

three. The output of the match signal, the incremental value are OC (open collector), RS422 (line driver, a differential line driver, TTL), push-pull (HTL, push-pull), etc., can be found to replace, and the absolute encoder has parallel (parallel, signal output line number), SSI serial (signal cables have clock + -, date + -), Canopen, Profibus-DP and other bus (signal cables have A, B, etc.), it may also have been Shanghai Jing Pu electromechanical absolute value of GM series product family to find a replacement.
Universal signal output Replacements: Shanghai Jing Pu Electric Co., GA, GM series also offers an intelligent signal output, while the output 4-20mA and RS485 signals, both signals can be found almost in all the appropriate instrument or PLC, PC connection interface, and absolute encoder working range and resolution of single or multi-turn, are set as needed. This encoder for imported users do not understand the situation encoder output, more convenient to replace imports, without encoder output with the original form, but according to the practical application of direct use.

four. Principle nature encoder distinguish between incremental encoders, single-turn absolute value encoders, absolute multi-turn encoder, a special type of encoder. Now most of the incremental encoder can already replace (for example GI60, HA78, etc.), is not difficult, but also can use GMS412 absolute value of a single-turn encoder 17 (17Bit) or less, GAS60 replace absolute multi-turn encoder 28 can also replace the following (with GAX60 or GMX425 replaced). There will be "-500", the general import encoder label "--512", "- 600", "- 1000", "- 1024", "--2048" and other figures, mostly incremental encoder the above figure is the number of output pulses; and on the label "absolute" and the words "8" "10" "12" "13" "16" "bit" and other, mostly single-turn encoder; and on the label there are "absolute" "multiturn", and the "1212" "1213" "24" "25" "26" and other words, most of which are multi-turn absolute encoder; or, in some European brands, the models have " S "for single-turn encoders, type in" M "for multi-turn encoder. (Type in "I" or the signal output is "A, B, Z" for incremental encoder)

Fives. Install matching shape, the shape is a mounting flange form with clamping flange, servo flange, sleeve type, etc., you can read my previous blog or on our website www.gemple.cn to understand; second is the outer diameter, is now generally 58, 60,65,78,90 (mm), etc. can be found to replace, for example, imports encoder models XXM58 (eg AVM58), (such as AC58), XXS58 (such as FVS58), XXI58 (such as AVI58), XXS60, XXM60, XX65 (eg CE65), XXX90 etc., already have most of the domestic products can be replaced; third shaft, in fact, this right - by coupling aperture adjustment installation.
