High speed door positioning method

Let's take a look at the three positioning methods of the high-speed door.

High-speed door is another name for fast rolling door and high-speed rolling door. The high-speed door has many functions such as heat preservation, cold preservation, insect proof, windproof, dustproof, soundproof, fireproof, anti-odor, lighting, etc. The high-speed door is suitable for food, chemical, textile, electronics, Supermarkets, refrigeration, logistics, warehousing and other places can meet high-performance logistics and clean places, save energy, automatically shut down at high speed, improve work efficiency, and create a better working environment.

There are three ways to position a high speed door:

Mechanical stroke positioning: This positioning method and the position of the rolling gate are almost the same. The period is excellent: the speed is fast and the requirements on the controller are low. But the technology is backward.

Magnetic switch positioning: The principle is similar to that of the air shower door. The disadvantage is that it is easy to cause the limit deviation.

Rotary encoder positioning: This mode is a bit accurate, the theoretical value is 0.3mm, the limit setting is simple, and with the incremental compensation function, it is simple and convenient, and people or large equipment can move in and out more freely, and save resources. Waste.
