Parameter of famous brand of 5L-H3 electric machinery: 200V, 133HZ, 2000r/min, 5.
6A 2, systematic hookup: 3, systematic program: Vulture mill machine uses control of V/F open loop, AI1 imitate terminal gives linear velocity, digital terminal stops since X1 control machine. Set parameter of transducer electric machinery correctly, with V/F multistage curvilinear control, vulture mill machine is achieved bigger exert oneself. Pass parameter of electric machinery nameplate, we can calculate electric machinery is basic running frequency and parameter of P9 group electric machinery are as follows: 1, electric machinery is basic running frequency F: 133/200=X/380, solution gets X=252.
7HZ, take number of F=250HZ 2, electric machinery pole: N=60*f/n=60*133/2000=3.
99=4, reason electric machinery has 4 extremely several pairs, for 8 extremely electric machinery, p9.
01=8 3, electric machinery is rated revolution: R1=60*250/4=3750r/min, because actual and rated rotate speed is put in the error, slant commonly small, reason is actual and rated rotate speed but set is: R2=3700 R/min, namely P9.
Rated power of 02=3700 R/min 4, electric machinery: By electric machinery rated electric current is 5.
6A, can get electric machinery rated power is 2.
2Kw, reason P9.
2kW 5, electric machinery is rated electric current: P9.
Sky of 6A 6, electric machinery carries electricity: I=5.
24A, we take P9.
5A 4, the function piles up a setting: Original setting function piles up parameter to be: P0.
02=1500 R/min, P9.
7 KW, P9.
When 0A is installed by this parameter, vulture mill machine grinds cast strength not quite big, observe transducer moving parameter is right now: With 106.
8HZ frequency moves, output electric current is 0.
1A changes. Right functional code installs parameter to be: P0.
02=3700 R/min, P9.
2 KW, P9.
When 5A is installed by this parameter, vulture mill machine grinds cast strength to have increase apparently, observe transducer moving parameter is right now: Move with 80HZ frequency, output electric current is 1.
8A changes. Install a V/F right now multistage curvilinear dot, can better promotion transducer exerts oneself: P4.
06=58% , P4.
08=100% , observe transducer moving parameter is again right now: Move with 80HZ frequency, output electric current is 1.
0A changes. Vulture mill machine grinds cast strength to have increase apparently. Promotion V/F graph is: 5, note: 1, can know by contrast of parameter of above input transducer, by electric machinery nameplate computation inputs transducer correct parameter is very important, such electric machinery exert oneself bigger, can satisfy the client's requirement more. 2, V/F curve adjusts parameter setting increases with voltage of correspondence of a frequency commonly 10% raise a dot to be beneficial for, 133HZ is for instance corresponding 200V, promotion voltage is beneficial to 220V here. After V/F curve adjusts, want to be able to increase a machine to exert oneself, for the standard that whether sets, machine of observation carve mill grinds cast to exert oneself degree how. 3, electric current of indication output of transducer of the observation in debugging a process and running frequency, observe burnish cast is presentative next, will decide with this adjust whether does parameter satisfy a requirement.
