The connection of the Mitsubishi inverter FR-A800

Torque control: Torque control is based on external simulation imitation typing or direct address assignment to set the output torque of the motor shaft. For example, 10V matches 5Nm. When the external simulation simulation is set to 5V, the output of the motor shaft is 2.5Nm. If the load of the motor shaft is less than 2.5Nm, then when ...

A: E700 is an economical and small inverter with high driving performance, with the function of holding the brake, and can also add options to expand the function, which can be used for transportation, lifting occupations, and has high cost performance. Q: Mitsubishi inverter E740 should ...

1. The switching signal of PLC controls the inverter The output point and COM point of the PLC (MR type or MT type) are directly connected to the STF (forward engine), RH (high speed), RM (medium speed), RL (low speed), and input SG ports of the inverter. The PLC can be programmed to control the inverter's start, ...

When the FR-CS80 inverter detects an abnormality, it will display an error message or alarm in the operation panel according to the abnormal content, or maintain the function action and block the output of the inverter. When maintaining a function operation, please deal with the cause of its operation before resetting the inverter, and then start working. ...

When calculating the electronic gear ratio of the Mitsubishi servo motor, the first thing to pay attention to is to check whether your Mitsubishi servo motor has been directly set to XX pulse one turn, if this parameter is not directly set, we can go through a simple formula to calculate the electronic gear ratio of the Mitsubishi servo motor. ...

A. A scanning cycle is divided into input sampling, program fulfillment, and output rewriting. B. Each scanning process. The convergence samples the input signal. The convergence rewrites the output signal. C. Component image register ...

1. Select the power supply with excellent performance and press the disturbance introduced by the power grid The power supply of the PLC controller is powered by a non-power line, and is powered by a special line directly led by the main bus of the low-voltage distribution room. Isolation transformer should be selected, the transformer capacity should be 1.2-1.5 times larger than the actual need, and can be used in isolation...

Generally, there are three types of Mitsubishi PLC output circuit methods, namely: relay output type, transistor output type and thyristor output type. So what are the characteristics of each of them? First, the relay output circuit Use of relays ...

1. The transistor output type of the FX series generally sends pulses to the servo through the output point of Y0, Y1 or the positioning module, and the speed and direction of the servo depend on the frequency and direction of the pulse in your program. Mitsubishi FX3U series ...

1. The acceleration and deceleration time constants are at fault. Solution: Increase the acceleration and deceleration time constants to check whether it is normal. 2. The torque constraint value is abnormal. Solution: Increase the torque constraint value to investigate whether it returns to normal. ...

Many novices in the electrical industry are not sure how to start debugging after completing the planning links such as electrical control cabinets and PLC programs. Perhaps some people due to inappropriate debugging methods have led to PLC burning and other problems, so how should the planned electrical system be debugged? Follow these seven steps. ...

When you are ready to communicate through AJ71QE71, perform the ping procedure in MS-DOS mode to check if the connection is correct before the Mitsubishi PLC's GPPW starts to communicate. Support communication with Weilun touch screen through serial port. Under...

In the process of operation, low-voltage electrical appliances will present problems due to improper use or long-term operation of aging components, and there are many kinds of problems, and the common problems are analyzed and dealt with. 1. Contact problems and repairs The contact is the primary component of the low-voltage switching coupon, ...

When you are ready to communicate through AJ71QE71, perform a ping in MS-DOS format to check if the connection is correct before the Mitsubishi PLC's GPPW starts to communicate. The support communicates with the Weilun touch screen through the serial port. ...

The reasons for the loss of the PLC program are the lack of battery power supply for the user's saved program, the internal circuit of the PC, the motherboard burned out due to the impact of external high voltage such as lightning strikes, etc., which will be encountered in our PLC control system. For example, the old type of plc such as the FX2N series, which has been discontinued...

Internal memory programs, logic operations, sequential manipulation, punctuality, counting, arithmetic operations, and other programmable memories are used to manipulate a variety of machinery or production processes with digital or analog inputs/outputs. PLC-related peripherals should be easy to operate with industry to form a whole, easy to expand...

Installation and commissioning of the system Reasonable arrangement of system installation and commissioning procedures is the key to ensure that the installation and commissioning mission is completed efficiently and with high quality. 1. Preliminary skill preparation The more abundant the skills to prepare for the commissioning of the system device, the smoother the installation and commissioning will be. Former...
