Set the parameters when reading and uploading the Delta PLC program

The non-standard manipulator can be customized according to the practical needs of customers, because the non-standard manipulator has no specifications to follow, and there is no such kinematic model in the controller, so the development of the control system is difficult. Delta recently provided non-standard manipulators for pharmaceutical board manufacturers to supply control solutions ...

Delta inverter is a device that converts the power supply (50Hz or 60Hz) into AC power supply of various frequencies to realize the variable speed operation of the motor.

Short-circuit maintenance (overload maintenance) is an important function of circuit breakers, and the reason why this function is achieved is that the circuit breaker senses the temperature in the circuit through a thermal iron plate. Once the temperature in the circuit is too high, it is transmitted to the mechanical mechanism in the circuit breaker for trip maintenance. ...

Reflected waves that affect the impedance mismatch between the cable and the motor are pervasive in all AC VFD applications. The severity of the problem depends on the length of the cable, the rise time of the PWM (Pulse Width Modulation) carrier, the voltage of the VFD, and the magnitude of the impedance difference between the motor and the cable. ...

Delta's thermostat is a commonly used temperature control device, which can adjust the temperature according to the user's needs, and then achieve the intention of saving energy. The effect and use of Delta thermostats are also very widespread, so let's introduce the effects and uses of Delta thermostats. ...

As factories move from automation to intelligence, the requirements for equipment performance and scalability are progressing day by day. In response to the rapid development of electronic engineering, transportation and mechanical engineering and other occupations, in order to quickly manufacture related product parts and components, metal coil winding technology is also being carried out at a high speed.

After the installation of the Delta inverter is completed, disconnect the output of the inverter, use the diode file of the digital meter to measure the input and output of the inverter before the power is not turned on to ensure that there is no short circuit, and then turn on the operating power supply of the inverter.

1. Circuit breaker A circuit breaker is a device that can be manually or automatically controlled, and is used to control the on/off of the system power supply in the equipment circuit system. When there is a suspicion that there is a defect in the electrical system of the equipment, the primary functional part of the power supply should be checked. Under normal circumstances, when in the ON state, the input input ...

Automatic: P0-02 Drive Status Display Parameter Function: 07Motor Speed (r/min) P1-01 Control form and control command input source setting parameter function: 02 Select S form (r/min) P1-38: Zero speed detection accuracy (no response below set speed) P1-4 ...

There are many setting parameters of the inverter, and each parameter has a certain selection scale, and the inverter can not operate normally due to the improper setting of a single parameter is often encountered in the application, therefore, the relevant parameters must be correctly set. ...

1. Control mode: i.e. speed control, torque control, PID control or other methods. After the control method is adopted, static or dynamic identification should generally be carried out according to the control accuracy. 2. Minimum operating frequency: That is, the minimum speed of the motor. When the motor is working at low speed, the ...

1. Ability to adapt to the environment 1.1 Ability to adapt to grid voltage fluctuations When the motor on the bus starts in a group, when the largest motor unit on the bus starts, the influence on the operation of the inverter, which is related to the input voltage fluctuation range parameters promised by the inverter.

When selecting a Delta servo motor, in principle, the selection should be based on the load conditions. There are two types of loads on the motor shaft, namely damping torque and inertial load. Both loads should be calculated correctly and their values should meet the following criteria: 　　1) When the machine is running with no load, in the whole speed range, Delta ...

1. The main reason for VFD overload (1) Mechanical overload. The main characteristic of overload is the heating of the motor, which can be detected by reading the operating current on the display. (2) The three-phase voltage imbalance leads to excessive running current in a certain phase, resulting in overload tripping. It is characterized by uneven heating of the motor ...

If the inverter is to run the equipment again after being shelved for more than half a year, the probability of damage may be greatly increased due to many factors such as the placement environment, the service life of the inverter, and the load rate, and the failure usually presents the following problems: ...

1) When taking out or placing the servo motor, it is not possible to only pull the wire and drag the motor or only hold the rotating shaft core. 2) Do not hit the shaft directly, e.g. by tapping or hammering, as this may cause damage to the shaft and the encoder attached to the opposite side of the shaft. 3) Give the shaft core ...

1) Power electronic equipment power electronic equipment is in the circuit to play the effect of on-off and complete a variety of converter equipment, VFD is the installation of this converter, so it is with the development of the inverter equipment and unfold, the quality of the inverter equipment depends on its on-off ability, accept the on-off current and amount...

1. Control the starting current of the motor: when the motor is directly started through the I frequency, it will generate 7 to 8 times the rated current of the motor, and this current value will greatly increase the electrical stress of the motor winding and generate heat, thereby reducing the life of the motor. The acid frequency speed regulation can be started at zero speed and zero voltage (can also be ...

1. Before the inverter is energized The temperature and humidity of the surrounding environment should be detected first. Too high a temperature will cause the inverter to overheat the alarm. When severe, it will directly lead to damage to the power supply device of the inverter and short circuit of the circuit; Excessive humidity of the air can lead to a direct short circuit inside the inverter. When the inverter is in operation ...

The motor can be started after the work is completed before use, and attention should be paid to the investigation of the motor, transmission device, production machinery and line voltage and ammeter, if there is an abnormal phenomenon, it should be stopped immediately, the fault should be identified and swept away, and then it can be closed and started again. When the motor is running, ...
