1, with a hand wheel shaft jitter. Originally for the handwheel is A problem with the circuit board inside the box, replacement of damaged components 2, hand wheel, sometimes good sometimes bad to use, no laws, it is the handwheel or within the handwheel extension resistance is too large, replace the backup line problem solving 3, hand wheel insensitive reaction, serious pulse leakage phenomenon, originally is the pin plug connection cannot be used in place of 4, hand wheel, originally for signal lines of small plug in A/B the X1 X2 against 5, hand wheel cannot be used or hand wheel pulse leakage phenomenon, the original is the cable line jump needle is wrong, should jump on both sides to keep the middle, cable line DIP - - - - - - - FIX switch ( S1 - - - - - - - S6) Set the following switch S1 S2 S3 S4, S5 S6 on open open open close close off 6, hand wheel cannot be used or hand wheel pulse leakage phenomenon, signal cable fx2002-6 4AA21- 0 xx0, bolt or virtual cannot be used after 7, hand wheel, the original for the pulse generator is broken, can only change the handwheel classification: hand wheel according to the national standard, the national standard is divided into two kinds. According to raw material points can be divided into: natural rubber wheel and plastic handwheel bakelite wheel wheel according to the style points are mainly small hand wheel, corrugated hand wheel, hand wheel, small ripple back corrugated hand wheel, round flange handwheel, double handle the handwheel, cast iron plating flipping the handwheel, plane wheel, double amplitude of hand wheel, and so on. The handwheel USES: mainly used in machine tool equipment, printing machinery, textile machinery, packaging machinery, medical equipment, petroleum and petrochemical equipment, the lid of the boiler accessories and so on. Handwheel production raw material: natural rubber wheel main USES such as bakelite, plastic natural rubber wheel because of its strong elasticity, plasticity and good insulation, waterproof trapping, tensile and wear resistance and other characteristics, widely used in industry, agriculture, national defense, traffic, transportation, machinery manufacturing, medicine and health care field and daily life, etc. , such as the transportation in the tyre; Industrial use of conveyor belt, transmission belt, all kinds of sealing ring; Medical gloves, blood transfusion tube; Used in the daily life of rubber shoes, raincoat, warm water bag is made of rubber wheel as the main raw material, the defence used on aircraft, artillery, tanks, even in the field of cutting-edge technology to the rockets, satellites, spacecraft, space shuttle, and so on all need a lot of rubber wheel parts. The flexibility of natural rubber wheel its raw rubber without too much and the crosslinking density of the vulcanizates of elasticity is high. For example, in 0 100 ℃ range, resilience in 50 - Between 85 ℃, its elastic modulus is only 1/3000 of the steel, elongation is 1000%, stretching to 350%, after retract a permanent deformation is only 15%, the flexibility of natural rubber wheel is high, second only to butadiene rubber wheel in the general rubber wheel.
