Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in Figure 1: many motor synchronous control device comprises industrial control computer 1, frequency converter and motor 5; Described industrial computer 1 connects fieldbus by data interface unit 2; Be connected with network adapter on the fieldbus, each network adapter is connected with a frequency converter, and the output of frequency converter connects motor 5; Described frequency converter comprises primary transducer 4-1 and from frequency converter 4-2; The network adapter that is connected with primary transducer 4-1 is master network adapter 3-1, is from network adapter 3-2 with the network adapter that is connected 4-2 from frequency converter.
One in the described frequency converter is designated as primary transducer 4-1, and all the other are from frequency converter 4-2.
Described data interface unit 2 is selected the 1770-KFD interface unit for use, and described fieldbus is the DeviceNet fieldbus, and described network adapter is selected the 20-COMM-D adapter for use, and described frequency converter is selected PowerFlex 70 frequency converters for use.Described industrial control computer 1 is connected on the DeviceNet fieldbus by data interface unit 2, and an end of network adapter 3 is connected on the DeviceNet bus.Described industrial control computer 1, network adapter, frequency converter and motor 5 constitute communication and Control Network by the DeviceNet fieldbus.
According to the work on the spot environment, select a frequency converter as primary transducer 4-1, its corresponding network adapter that connects is as master network adapter 3-1, and other network adapter be from network adapter 3-2 in the network, with the frequency converter conduct that is connected from network adapter 3-2 from frequency converter 4-2.
As shown in Figure 2: master network adapter 3-1 carries out software initialization, has the following steps: s1. opens data link A (B); S2., peer I/O data are set by link A (B) output; S3. select to make the slave unit of response; S4., the time of transmitting data is set; S5. adapter is exported peer I/O data enable; S6. adapter resets.
As shown in Figure 3: carry out software initialization from network adapter 3-2, have the following steps: s7. forbids the I/O message commands by the scanner input; S8., peer I/O data are set by connecting A (B) input; S9., main equipment is set selects the main equipment node number that is connected with slave unit as the pantograph ratio s10. of slave unit speed reference: the s11. setting is from the stand-by period of adapter; S11. accept peer I/O data enable; S12. adapter resets.
After the initialization of master-slave network adapter finishes, adopt DriveExplorer software that principal and subordinate's frequency converter and principal and subordinate's adapter are carried out the parameter setting, and then finish the control corresponding requirement.
The control logic value of primary transducer 4-1 is sent by data link A1, and speed reference is sent by data link A2.Man-machine interface by primary transducer 4-1 starts simultaneously, stops, and turns to crawl principal and subordinate frequency converter.Speed by regulating principal and subordinate's frequency converter makes from motor and follows main motor action by the certain speed ratio with reference to recently adjusting from frequency converter 4-2 relatively and the speed of service of primary transducer 4-1.The online modulability of its speed is applicable to that the motor of whole piece circuit uses the speed different with main equipment operation respectively.Every motor again can be by its each parameter of control requirement independent regulation.Primary transducer 4-1 transmits other parameters of primary transducer 4-1 by data link B, thereby more accurately controls from the trace performance of frequency converter 4-2.
