Description
Technical field
The utility model relates to conveyer control technology field, especially a kind of Dual-motor synchronous control system.
Background technology
Synchronous control system often can use in painting dressing automobiles pipeline, and in automobile pretreatment conveying line, top, side machine has two motors, needs these two motor in synchrony to run, and needs to ensure that run location is identical.Simultaneously simultaneously Synchronization Control general at present control two motors by program to run, as shown in Figure 1; But run process in, cannot checkout equipment run physical location, whether real in synchronous operation, this control mode existence and stability is poor, and it is unreliable to control, and cannot detect the problems such as physical location.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of frequency converter master & slave control system, can control bi-motor more reliably synchronous, and have employed encoder, and system can care testing device position, ensures the reliability controlled.The technical solution adopted in the utility model is:
A kind of frequency converter master & slave control system, comprises the first frequency converter of built-in synchronization module and the second frequency converter of built-in synchronization module, the first rotary encoder and the second rotary encoder, synchronous data line, the first data wire and the second data wire;
First motor and the second motor are connected the first frequency converter of built-in synchronization module and the second frequency converter of built-in synchronization module respectively; First rotary encoder and the second rotary encoder are arranged on the first motor and the second motor respectively, and are connected the first frequency converter of built-in synchronization module and the second frequency converter of built-in synchronization module respectively by the first data wire and the second data wire; First frequency converter of built-in synchronization module and the second frequency converter of built-in synchronization module are interconnected by synchronous data line;
First frequency converter of built-in synchronization module and one of them frequency converter of the second frequency converter of built-in synchronization module are set to primary transducer, and another is set to from frequency converter; Primary transducer and realize data communication by synchronous data line from frequency converter.
The utility model has the advantage of:
1) control conveniently: only need to control primary transducer, and do not need to control from frequency converter.
2) detect reliably: employ encoder detection position, control more reliable.
3) stable: to adopt the Synchronization Control of frequency converter own, equipment runs more stable.
Accompanying drawing explanation
Fig. 1 is common synchronization control system schematic diagram.
Fig. 2 is SEW frequency converter synchronous control system schematic diagram of the present utility model.
Embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
The utility model is the master & slave control application of SEW frequency converter in automobile pretreatment conveying line, realizes bi-motor synchronous with SEW frequency converter and rotary encoder, can be more reliable and more stable to realize two-shipper synchronous.
The present embodiment, for top, side machine equipment, illustrates how SEW frequency converter realizes bi-motor by master & slave control synchronous.
In common synchronization control system, as shown in Figure 1, the first motor 2 and the second motor 4 are connected the first frequency converter 1 and the second frequency converter 3 respectively, control two frequency converters simultaneously and run during control.Owing to not adopting encoder, so the running status of equipment reality cannot be known in running, once equipment goes wrong, cannot arrestment in time, ensure safety.
The frequency converter master & slave control system of the improvement that the utility model proposes, as shown in Figure 2, comprise the first frequency converter 5 of built-in synchronization module and the second frequency converter 7 of built-in synchronization module, first rotary encoder 6 and the second rotary encoder 8, synchronous data line 9, the first data wire 10 and the second data wire 11;
First frequency converter 5 of built-in synchronization module and the second frequency converter 7 of built-in synchronization module all adopt the frequency converter of SEW company, and model is SEW frequency converter MDX61B0015-5A3-4-0T.
First motor 2 and the second motor 4 are connected the first frequency converter 5 of built-in synchronization module and the second frequency converter 7 of built-in synchronization module respectively; First rotary encoder 6 and the second rotary encoder 8 are arranged on the first motor 2 and the second motor 4 respectively, and are connected the first frequency converter 5 of built-in synchronization module and the second frequency converter 7 of built-in synchronization module respectively by the first data wire 10 and the second data wire 11; First frequency converter 5 of built-in synchronization module and the second frequency converter 7 of built-in synchronization module are interconnected by synchronous data line 9;
First frequency converter 5 of built-in synchronization module and second one of them frequency converter of frequency converter 7 of built-in synchronization module are set to primary transducer, and another is set to from frequency converter; Primary transducer and realize data communication by synchronous data line 9 from frequency converter; The positional information of the first rotary encoder 6 and the second rotary encoder 8 can send the first frequency converter 5 of built-in synchronization module and the second frequency converter 7 of built-in synchronization module to respectively by the first data wire 10 and the second data wire 11;
During control appliance, only need to control primary transducer (supposing that frequency converter 5 is for primary transducer) and run, when primary transducer is run, can go to control to run from frequency converter (supposing that frequency converter 7 is from frequency converter) by synchronous data line 9; The motor speed of service and position can be detected in real time by encoder, accept the corresponding encoder position of primary transducer from frequency converter by synchronous data line 9, automatically follow primary transducer running.Thus ensure the reliability of control.It is synchronous that above-mentioned control procedure can reliably realize bi-motor.
