1. Control requires different timings of the timer to control its speed.
The stepping motor is forward-reversed by timing the timer through and off.
This article uses a Siemens S7-200plc for five-phase ten-step stepper motor as an example.
2. Five-phase ten-step stepper motor control requirements
1) The five-phase stepping motor has five windings: A, B, C, D, and E. The timing diagram for controlling the five-phase ten-beat motor is as follows:
Switch 1 controls its operation (start/stop)
Switch No. 2 controls its low speed operation (0.5S is required to turn over a step angle)
Switch No. 3 controls the speed operation (0.1S is required to turn a step angle)
Switch No. 4 controls its low speed operation (0.03S is required to turn a step angle)
Switch No. 5 controls its steering (ON is forward rotation, OFF is reverse rotation)
3.PLC external wiring diagram
The design of the input and output devices of the PLC external wiring diagram, the type of load power supply, etc. are set in conjunction with the control requirements of the system. Its control wiring diagram is shown below:
4. I/O address assignment According to the PLC external wiring diagram, each electrical component symbol, function description table and I/O address allocation table can be written as follows:
5. The ladder diagram of the five-phase ten-beat stepping motor is as follows:
Gear Reducer Motor is a small precision reducer, and the size and specification can be customized below 38mm. Shenzhen shun cheong electrical co., LTD. 15 years engaged in the design, development, manufacture Dc Gear Motor, products applicable to the smart home, widely used in intelligent robot voice interaction, children's education escort robot, intelligent sweeping machine robot, intelligent robot adaptability, independent motor, intelligent medical robot project.
Application field:
Method of use: the best stable in horizontal plane, installed on the gear reducer motor output shaft parts, cannot use a hammer to knock,knock prone to press into the gear reducer motor drive, may cause damage to internal components, and cannot be used in the case of blocked.
Operating temperature range:
Gear reducer motor should be used at a temperature of -10~60℃.
The figures stated in the catalog specifications are based on use at ordinary room temperature catalog specifications re based on use at ordinary room temperature (approximately20~25℃.
If a geared motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.
Storage temperature range:
Gear reducer motor should be stored ta a temperature of -15~65℃.
In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.
Service life:
The longevity of gear reducer motor is greatly affected by the load conditions , the mode of operation,the environment of use ,etc.Therefore,it is necessary to check the conditions under which the product will actually be used .The following conditions will have a negative effect on longevity.Please consult with us should any of them apply.
â—Use with a load that exceeds the rated torque
â—Frequent starting
â—Momentary reversals of turning direction
â—Impact loads
â—Long-term continuous operation
â—Forced turning using the output shaft
â—Use in which the permitted overhang load or the permitted thrust load is exceeded
â—A pulse drive ,e.g.,a short break,counter electromotive force,PWM control
â—Use of a voltage that is nonstandard as regards the rated voltage
â—Use outside the prescribed temperature or relative-humidity range,or in a special environment.
â—Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.
when it come to volume production,we're a major player as well .each month,we rurn out 600000 units,all of which are compliant with the rohs directive.Have any questions or special needed, please contact us, we have the engineer group and best sales department to service to you Looking forward to your inquiry.
