Embodiment Construction

[0018] refer to figure 1 , The frequency converter control system in the embodiment includes PLC1, data line 2, single-chip microcomputer 3, MODBUS data line 4 and ABB frequency converter 5. The data line 2 is connected between the output end of the PLC1 and the input end of the single-chip microcomputer 3 , and the MODBUS data line 4 is connected between the output end of the single-chip microcomputer 3 and the input end of the ABB frequency converter 5 .

[0019] The inverter output frequency control method in the embodiment includes the following steps:

[0020] Step 1 Build the inverter control system

[0021] Step 2 Control the output of PLC1

[0022] When it is necessary to change the output frequency of ABB inverter 5, the output terminal of PLC1 first outputs the high eight-bit binary data, with a delay of 10 milliseconds; secondly, the output of PLC1 returns to zero, with a delay of 10 milliseconds; finally, the output terminal of PLC1 outputs the low eight-bit bina...

Abstract

The invention relates to the technical field of electric control and specifically relates to a transducer control system for timely communication of a steel frame compound pipe production line. A single chip instead of ABB transducer communication board card is utilized to realize the communication and control of PLC on the ABB transducer, so that the problem that production is affected by an overlong supply period after the ABB transducer communication board card is damaged is solved. The transducer control system provided by the invention comprises a PLC, a data line, the single chip, a MODBUS data line and the ABB transducer. The data line is connected between an output end of the PLC and an input end of the single chip. The MODBUS data line is connected between the output end of the single chip and the input end of the ABB transducer.

Description

technical field [0001] The invention relates to the technical field of electrical control, in particular to a frequency converter control system for timely communication in a steel skeleton composite pipe production line. Background technique [0002] In the production process of steel frame plastic composite pipe, PLC controls the output frequency of ABB inverter through field bus and ABB inverter communication board to realize equipment speed adjustment. When the communication board of the ABB inverter is damaged, it is generally difficult to repair and can be replaced directly. However, the delivery period of the communication board of the ABB inverter is long, usually two weeks, which has a great impact on normal production. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a frequency converter control system for timely communication of the steel skeleton composite pipe production line, which uses a single-chi...
