The direct current speed regulator mainboard test system comprises a PLC controller and a direct current speed regulator, wherein the PLC controller comprises a controller output terminal, a controller input terminal and a central processor, the central processor is used for processing signals transmitted by the controller input terminal and transmitting operation state word signals to the controller output terminal, the direct current speed regulator comprises a terminal input terminal and a terminal output terminal, the controller output terminal transmits aenablement and operation demand signals to the terminal input terminal, and the terminal output terminal transmits device operation state signals to the controller input terminal. The direct current speed regulator mainboard test system saves equipment maintenance cost, reduces equipment fault risks, further realizes function expansion and carries out similar tests for other industrial control components.
Description
Technical field
The utility model relates to a kind of frequency converter or direct current speeder fault diagnosis system, in particular, relates to a kind of direct current speeder main board testing system.
Background technology
Some faults can occur in widely used frequency converter and direct current speeder in actual use in industrial enterprise, have plenty of the problem of device own, the abnormal occurrence that also has external cause to cause.Receive run signal as direct current speeder, but can't normally to move, often in order resuming production fast, to exist the element of fault all to change suspection when troubleshooting, comprising the direct current speeder mainboard: the CUD1 plate, its cost is higher, and is as intact in judging whether, just can not come into operation again, cause waste, as take a risk to use, may exist to cause fault, cause the risk of larger loss.
The utility model content
Technical problem to be solved in the utility model is to overcome the shortcoming of prior art, the direct current speeder main board testing system that provides a kind of and be easy to detecting element, avoids fault to occur, reduce the loss.
In order to solve above technical matters, the utility model provides a kind of direct current speeder main board testing system, comprise PLC controller and direct current speeder, described PLC controller comprises controller output end, controller input terminal, central processing unit, described central processing unit is processed the signal that described controller input terminal transmits, and running status word signal is sent to described controller output end; Described direct current speeder comprises terminal input terminal and terminal lead-out terminal, and described controller output end transmits and enables and move given signal to described terminal input terminal; Described terminal lead-out terminal conveyer operating state signal is to described controller input terminal.
The technical scheme that the utility model further limits is: described controller output end, controller input terminal, terminal input terminal and terminal lead-out terminal are the digital quantity terminal.
Further, described system also comprises the warning device that is connected with the PLC controller.
The beneficial effects of the utility model are: a kind of direct current speeder mainboard test platform described in the utility model carries out functional test by method easily to the direct current speeder mainboard, be easy to the direct current speeder fault is judged, saved cost of equipment maintenance, reduced the equipment failure risk, simultaneously also carry out multifunction, other industry control elements are similarly tested.
Description of drawings
Fig. 1 is the structural drawing of a kind of direct current speeder main board testing system described in the utility model.
Embodiment
Embodiment 1
A kind of direct current speeder main board testing system that the present embodiment provides, structure as shown in Figure 1, comprise PLC controller and direct current speeder, described PLC controller comprises controller output end, controller input terminal, central processing unit, described central processing unit is processed the signal that described controller input terminal transmits, and running status word signal is sent to described controller output end; Described direct current speeder comprises terminal input terminal and terminal lead-out terminal, and described controller output end transmits and enables and move given signal to described terminal input terminal; Described terminal lead-out terminal conveyer operating state signal is to described controller input terminal.Described controller output end, controller input terminal, terminal input terminal and terminal lead-out terminal are the digital quantity terminal.In addition, native system also comprises a warning device that is connected with the PLC controller, is used for providing warning message when abnormality being detected.
In the present embodiment, the PLC controller uses Siemens S7-200 series of PLC controller, and its pin I0.0 is digital-quantity input terminal, and pin Q0.0, Q0.1 are the digital output terminal.Direct current speeder uses Siemens 6RA70 series, and its pin 37# and pin 38# are the direct current speeder digital-quantity input terminal, and pin 37# transmits run signal, and pin 38# transmits enable signal, and pin 46# is the digital output terminal, transmits running status.
Pin Q0.0, the Q0.1 of PLC controller is connected with the pin 37# of direct current speeder, and the pin Q0.1 of PLC controller is connected with the pin 38# of direct current speeder; The pin I0.0 of PLC controller is connected with the pin 46# of direct current speeder.
The principle of work of the described direct current speeder main board testing system of the present embodiment is, set the direct current speeder parameter at the PLC controller, terminal lead-out terminal conveyer operating state signal is to the controller input terminal, the number of times that the given run signal of PLC and direct current speeder return to running status compares in real time, and controller output end transmits and enables and move given signal to the terminal input terminal.Through the long-play test, when frequency difference namely provides alerting signal to warning device, send warning message, determine that mainboard damages, otherwise definite intact, can continue to use.
A kind of direct current speeder mainboard test platform described in the utility model carries out functional test by method easily to the direct current speeder mainboard, be easy to the direct current speeder fault is judged, saved cost of equipment maintenance, reduced the equipment failure risk, simultaneously also carry out multifunction, other industry control elements are similarly tested.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
