You already know that machines like cnc cutting tools, robots and elevators need signals to know where they are so they can move accurately and deliver the right results. And all this is possible because of a tiny guy called the absolute shaft encoder. This is a mini tool that tells the machine where it has stopped and what’s next. While most shaft encoders run a long run, it can still wear off after a point and you might be clueless about the mistake if you don’t look closely.
Don’t worry, it’s not as scary as it sounds to be, but it’s always smart to know when to change your encoder for quality work and safer manpower.
The Signs You Need to Replace the Absolute Shaft Encoder
- Your Machine Gives Wrong Position or Doesn’t Move Right
A high-resolution absolute shaft encoder gives very accurate position data. But if it’s worn out, that means the accuracy is gone and the machine is confused. So if your machine starts to cut in the wrong place, moves jerkily or behaves weirdly, it means the encoder is not reading the position anymore.
- No Signal or On-and-Off Signal
If you notice that your screen shows “no data” or “error”, stops suddenly during use, or if you notice that the movements become random, that could simply mean that the encoder’s internal parts have been damaged, or the wires are broken, or maybe the sensor is just dirty.
It Overheats or Vibrates Too Much
The Encoders should naturally stay cool and stable. But if it gets too hot, shakes a lot during machine use, or makes the machine noisy, it could mean that the machine needs a better encoder to deal with the rough conditions.
- You Upgraded Your Machine, But the Encoder Is Old
If you have upgraded your CNC to need more precision, started using the machine faster, or have moved the machine outdoors or to a dirty place then there is a chance that your old encoder may not be strong or smart enough anymore and you might need a multi-turn absolute shaft encoder for motor control systems.
- You Keep Replacing Encoders Too Often
Finally, if your maintenance team is changing encoders every few months, that’s not normal and must be stopped immediately. When you invest in good encoders like Brite Encoder’s industrial-grade absolute shaft encoder with SSI output, it will last for years.
However, if you experience frequent failures, it may mean that the encoder is not strong enough for your machine, or it’s not the right type.
Bottom Line
The absolute shaft encoder makes your machine smart enough to get things done like a pro, but sometimes a certain few mistakes or ignorance can cause delay to your work. This is why getting the best encoder for your machines and robots are the best choice for you. Start browsing now!
