1. No-load energizing test of Mitsubishi inverter. 1. Ground the ground terminal of the Mitsubishi inverter. 2 Connect the power input terminal of the Mitsubishi inverter to the power supply through the leakage maintenance switch. 3 Check whether the factory display window of the Mitsubishi inverter is normal, if it is not correct.

A PLC network consists of multiple subnets. The communication process of each subnet is determined by the communication protocol. The communication method is the core content of the communication protocol. The means of communication include visit control and data transmission. What are the three common communication methods of PLC? ...

When we select PLC as a controller for the construction of industrial automation production line, we should go through the following process, which is briefly described below: 1. First of all, the demand side, that is, Party A, needs to tell Party B what they want to achieve.

From raw material pulp to papermaking, and then through packaging and logistics, the paper towel finally completes the "transformation" to meet customers. The impression of packaging and quality, coupled with the comprehensive effect of multiple specifications, traceability, high standards, authoritative certification and other factors, will finally win the hearts of customers, and then establish a trustworthy ...

Mitsubishi Electric's fresh air system realizes indoor ventilation, but of course, we can't just replace the outdoor air into the room, a good fresh air should filter the harmful substances in the air, so that the air entering the room is not only fresh, but also clean and harmless. ...

1. Power indication (LED indication) When power is supplied to the Mitsubishi PLC root unit, the [POWER] LED indicator light installed on the surface of the root unit turns on. If the power supply is closed but the [POWER] LED does not illuminate, please acknowledge the power wiring. In addition, if the same power supply has a drive sensor, etc. ...

1. Occasions with brake servo motors: The servo motor is mainly loaded by the motor shaft, assuming that the load driven by the motor shaft is vertical, after the whole control system is powered off, the load on the servo motor shaft will be driven to run down under the action of gravity, so that ...

There is a very common kind of circuit in Mitsubishi PLC - the persistence circuit. The holding circuit means that when the external input switch is a button, it can press the button through the holding circuit to insist on the output, similar to the self-locking in the electrical diagram. We use Mitsubishi PLC as an example to write a sticking circuit. ...

The output point and COM point of PLC (MR type or MT type) are directly related to the STF (forward rotation engine) of the inverter. overflow-wrap: break-word !important; ">. RH (high speed), RM (medium speed) important; overflow-wrap: break-word !important; ">、R ...

1. Mitsubishi servo drive alarm code AL31.1 Fault analysis: It is the motor overspeed alarm. Cause analysis: 1. The frequency of a single pulse of the input command is too high; 2. The acceleration and deceleration time is too small, resulting in overshoot and too large; 3. Mitsubishi servo system is unstable; 4. Electricity ...
