Confirmation and clearing of Mitsubishi inverter FR-CS80 alarm history

Step Instruction (STL) is an instruction that uses internal software components to control the process step on top of the sequential control program. A step-to-back instruction (RET) is an instruction that is used to return to the main program (bus) after the state (S) process is completed. ...

1. First of all, the power supply should be cut off immediately and the circuit should be admitted whether it has been disconnected. 2. Next, check whether the fuse of the power supply is blown or whether the protector is tripped. Replace the fuse or reset the protector. Envy 3. Fuse ...

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. ...

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. ...

1. Set PA08 to 0003 and set the gain adjustment form to; , the function is to prevent the failure of the active calculation of the inertia ratio, and the alarm C005 will be given. 2. Flip it over; menu; , set the speed/acceleration and deceleration/movement amount, according to the actual situation ...

First, the control accuracy is different The step angle of the two-phase hybrid stepper motor is generally 1.8° and 0.9°, and the step angle of the five-phase hybrid stepper motor is generally 0.72° and 0.36°. There are also some high-performance stepper motors that have a smaller step angle after being subdivided. Communicate the control of servo motor ...

1. Hardware (1) I/O channeling, the PLC automatically detects the I/O fault and enters the STOP mode. (2) The I/O is damaged, and the program runs to the response signal that needs the I/O, and cannot execute the instruction downward. (3) Expansion module (functional, such as A/D) ...

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 ...

FX Series PLC: FX3G PLC has a built-in large-capacity program memory, 32K steps, and the basic instruction processing speed can reach 0.21μs in specification mode. In the meantime, the FX series 5U is suitable for any industry, and is used by small and medium-sized enterprises. For example, this year's very popular mask machine is suitable for FX5U, and he can ...

First, the frequency converter should not be installed on the equipment with a sensation, because the main circuit connection screw in the frequency converter is simply loose, and many frequency converters are damaged due to this reason. Second, the wiring problem: the input end of the inverter is connected to an air The initial maintenance current should not be too large, ...

1. Check whether the three-phase electricity of the motor is balanced (1) If the three-phase voltage of the motor is unbalanced, then check whether the three-phase voltage at the output end of the Mitsubishi inverter is balanced. (2) If the three-phase voltage of the Mitsubishi inverter is also unbalanced, the problem is inside the Mitsubishi inverter, and it should be investigated.

(1) Eliminate finger tremor: use the differential instruction DIFU (13) to retrieve the rising edge of the button to send the electrical signal, and the PLC only executes it once in an execution cycle, and then prevent such misoperation; (2) Unconscious operation: (1) Optimize the display function and use different fingers...

The inverter is the control equipment for the operation of the motor, and it has a certain maintenance function for the motor. Most of the inverter appliances have functions such as overvoltage, overcurrent, undervoltage and overload maintenance. Overcurrent maintenance function. In any link of motor acceleration, deceleration and constant speed operation, ...

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 ...

1. Data setting type This method is to set the current bearing as the origin. Therefore, at this time, no matter which direction the servo motor stops at, only the data setting type origin return is required, and now this direction is the origin direction. So, the origin regression operation under this method, ...

Servo drive system requirements 1. Wide speed regulation 2. High positioning accuracy 3. Satisfactory transmission rigidity and high speed stability 4. Fast response, no overshoot In order to ensure productivity and processing quality, in addition to the requirement of high positioning accuracy ...

1. Characteristics of the output reactor: 1. It is suitable for reactive power compensation and harmonic control 2. The primary effect of the output reactor is to compensate for the influence of long-line distributed capacitance, and output harmonic current according to the press; 3. Effectively protect the Mitsubishi inverter and improve the power factor, which can block the ...

01. Base system problem In Mitsubishi PLC, binary, octal, decimal 10, hexadecimal, 2-10 (BCD), etc., we need to master the conversion of 2-8 base. 2-8, the binary number is remembered from the back, every 3 dividends in a group, each group is separated into 8 bases, such as 1 ...

1. The servo mainly relies on the pulse to position, basically it can be understood in this way, the Mitsubishi CNC system maintenance servo motor receives a pulse, and it will rotate the angle corresponding to the pulse, so as to achieve displacement, because the servo motor itself has the function of sending out pulses, so the servo motor ...
