Poor braking resistance method:
Dynamic torque brake resistance
92 % R = 780/Electric KW
100 % R = 700/Electric KW
110 % R = 650/Electric KW
120 % R = 600/Electric KW
Inverter ::
1. Small electricity, large brake torque, flowing great
2. Can’t work for units is greater than large, otherwise the current, otherwise;
3. The braking time is artificially selected;
4. Small frequency frequency ≤7.5kW generally internal motor unit braking resistance;;;
5. When the braking is too late, it means that the resistance value is too late, and the discharge should be discharged.
Variable brake resistance power method:
Braking properties resistance power
General load w (kw) = resistance KWχ10℅
(KW) = resistance KWχ15℅ (kw) w (kw) w (kw)
W (kw) = resistance KW 20℅)
Regarding the problem of variable frequency interference:
During the interference, one power strong interference jeopher, the source of the interference intermiator intermiator internctor jam source source, then output the output output output output output output module module module of the output The interference jerk of the interference jelly intermiator intermiator intermiator intermiator intermiator intermiator intermiator intermiator intermiator intermiator intermiator intermiator intermiator intermiator intermiator intermiator intermiator antenna, poor ground line is poor The interference signal can go out and go out by sending it out. The line line is longer. The longer the line line, the larger the interference range, the larger the frequency converter signal and the input time. , Some of the inverters with reducing materials and reducing materials, sometimes sometimes order, communication electronic electronic equipment, equipment, equipment, equipment, equipment and equipment, human -machine interfaces, etc. You, wait, you, wait, wait, you must be careful when you buy, purchase, purchase, purchase, purchase, purchase, purchase, purchase, purchase, purchase, purchase, purchase, purchase, purchase, purchase, purchase, purchase, purchase, purchase, purchase, purchase, purchase, purchase, purchase, purchase, purchase frequency, and wiring, and you must be careful. Essence The prevention and control line plus magnetic rings, use, in the inside, enter and exit, the co -end of the line in Li Li cannot be grounded to check the frequency frequency interference, and it is very simple. Sometimes it is unknown. Essence Essence
People ask about learning and maintenance. Electronic electronic knowledge knowledge knowledge knowledge, knowledge knowledge knowledge knowledge, knowledge maintenance and maintenance device is good, you have considerable maintenance, maintenance, maintenance accessories accessories accessories accessories accessories accessories accessories accessories accessories accessories accessories maintenance and maintenance, also accumulated, also accumulated, also accumulated, also accumulated, also accumulated, also accumulated, also accumulated, also accumulated, also accumulated, also accumulated, also accumulated, also accumulated, also accumulated, also accumulated, also accumulated. It is also a considerable price. Reduction, maintenance costs, maintenance, maintenance, and maintenance, but the old modules are mostly returned and returned, so learning that the variable frequency is also electronically. It also often often uses the use of use and problem problem modules with everyone in the China Industrial Control Network frequency frequency consensus and the transmission forum forum with everyone. This is going on, this learns something, a lot of maintenance, and maintenance must be given to customers, customers and customers.
