Does absolute value encoder need battery?

Absolute encoders can record codes without relying on external power sources, sometimes need battery help. However, battery life is an often criticized part. If the encoder battery is dead, there is no difference between an absolute encoder an incremental encoder. The process of replacing the battery will inevitably affect the production of the equipment, but the frequency may be high, such as replacing the battery once a year. But the time of each replacement is very uncertain. It is troublesome to replace the encoder battery. The problem is the process of finding spare batteries inventory. the battery is difficult to prepare, because the battery is also a problem in the warehouse for a long time.

Taking the example just now, the equipment capacity is 1000 yuan/minute, each battery replacement takes 15 minutes (including the time to get spare parts the warehouse). The battery is replaced once a year, so there are 15,000 battery replacement operations per year for each encoder. Spent yuan. Therefore, long-life, high-performance encoder batteries are very expensive.

Therefore, some absolute encoders do need batteries, mainly sin-cos encoders, such as EnDat/Hiperface-Steggman, so there is no need to consider battery life. Of course, usually such encoders are cheap.

So, don't underestimate those trivial parts. A seemingly small change does involve a large amount of money, but its impact on productivity is small. In our production equipment, there are many such small parts, we will talk about it later.

The absolute encoder can reduce the initialization work of returning to the origin before running after the device is powered off, but it does mean that the device does need the function of returning to the origin. Because, when the transmission parts of the equipment are disassembled reassembled (for example, in the refurbishment process), the relative position of the encoder recording code the actual mechanical coordinates is lost, it needs to be re-initialized during debugging startup.
