Recently, a colleague encountered a problem and asked me to look at it. The encoders they are using often have no data. The fault phenomenon is that in normal use, the encoder value is fixed at a value that does not change. count. The encoder is Turck's incremental encoder, the module is FM450-1, the wiring is: 1A*, 1B*, 1N*, 1M and DC24V, and the 24V of the template is powered by an external Phoenix 24V power supply.
A TPU Screen Protector made of the super toughness of the honeycomb structure. Its unique ultra-soft properties allow it to cover the most complex curves and contours in a device.

Colleagues said that the encoder, the template and the cable have been replaced. When the problem occurs, the 24V power supply is also normal, but the problem remains. Since the device is ok, you can only consider grounding and interference. I remember that I have encountered similar problems before, and the encoder is not working properly due to the level. In the manual of the FM450, there is a sentence "The circuit of the counter input (encoder power supply, encoder signal) is electrically isolated from the CPU ground. Therefore, terminal 4 (1M) must be connected to the CPU ground with low impedance!" So, this colleague said, to measure the voltage of the encoder power supply for the CPU ground in normal use and fault, respectively, should be able to find the cause, the result is only 10V when the fault occurs, the template can not identify the signal, then naturally Not counting. Then the terminal 4 is grounded and the problem is solved.
The self-healing design of the Hydrogel Screen Protector can protect the display screen of the device from damage, leave no air bubbles, and maintain the sensitivity of the touch screen. Advanced anti-fingerprint and dust- and oleophobic overlays keep your screen smudge- and dirt-free. This overlay is also important in providing maximum touch sensitivity for improved high-speed glide and optimal touch response.
The optical transparency of the Hydrogel Film is more than 90%, showing you the most original screen color and bringing the most realistic visual experience.
