How to deal with Yaskawa servo alarm 840?

1. The LED light is green, but the motor does not move (1) Cause of failure: The motor in one or more directions is prohibited from operating. Solution: Check the +INHIBIT and –INHIBIT ports. (2) Cause of failure: The command signal is not to the driver signal. ...

Servo drive is a kind of controller used to control servo motor, its function is similar to that of an inverter acting on an ordinary AC motor, which is a part of the servo system and is mainly used in high-precision positioning systems. Servo drive is an important part of modern motion control, which is widely used.

1. Conditions for the static characteristics of the arc of Yaskawa welding robots In the welding production process, once the electrode material, gas medium and arc length are maintained, as long as the arc of the Yaskawa welding robot can burn stably, the welding current and arc voltage will show corresponding changes.

Checkpoints for daily use When inspecting and maintaining the inverter on a daily basis, it is necessary to check the temperature and humidity around you. Excessive temperature will lead to overheating alarms, and in serious cases, it may also lead to damage to some components or short circuits in the circuit. And the humidity in the air ...

In order to realize the anti-collision function of Yaskawa robots, there are two ways to connect external sensors, which are described below; In addition, how to dismiss alarms will be described in this article. 01. Directly connect to an external collision sensor 1. The machine in the door of the control cabinet ...

1. A.00 Absolute value data error: the absolute value data cannot be accepted or the accepted absolute value data is abnormal. 2. A.02 Parameter Destruction: The result of the "sum number check" of the user constant is abnormal. 3. A.04 User constant setting error: the set "user constant" exceeds the set ...

(1) Open modular control system architecture: using distributed CPU computer structure, divided into robot controller (RC), motion controller (MC), optoelectronic isolation I/O control board, sensor processing board and programming teaching box, etc. The Robot Controller (RC) and the programmed teaching pendant are connected via a string...

The fault codes of Yaskawa inverters are as follows: OC overcurrent; PG wiring is disconnected or wiring is incorrect; GF output ground fault ground short circuit ; PUF fuse blowing fuse blowing ; OV Main circuit overvoltage Main circuit overvoltage ...

OL2 is the inverter overload alarm, check whether it is a real overload or a false overload. 1. Test whether the output current of the inverter exceeds the rated current of the inverter, if it exceeds it, it may be the mechanical reason, if it does not exceed the inverter detection circuit is broken, and the false overload is reported. ...

There are three main burning methods for common Yaskawa robot servo motors: overload, phase loss, and short circuit. 1. Overload: Open the servo motor of the industrial robot to observe. The color of the entire winding wire pack has become dark and black, the end strap is cracked, and the serious phase insulation and notch insulation are due to overheating.

First, the basic wiring The main power input is 220V, which is connected from L1 and L3 (the actual use should refer to the operation manual); The control power input r and t can also be directly connected to 220V; See pages 22 and 23 of the operation manual for motor wiring, and see the operation manual for encoder wiring.

First, the wiring of the main circuit 1. The power supply should be connected to the R, S, and T terminals at the input end of the inverter, and must not be connected to the output terminal (U, V, W) of the inverter, otherwise the inverter will be damaged. After wiring, the fragmented wires must be cleaned, and the fragmented wires may cause abnormalities. ...

There are two scenarios in which the origin of the Yaskawa robot is lost: A. Loss of the origin of individual shafts; B. Lose all axis origins. All axes are created at the same time: When the combination of the robot and the control cabinet is changed, all axes are registered at the origin position at the same time. Each axis is created separately: change the motor or ...

1. Countermeasures to the overheating problem of inverter 1. For places where the operating environment temperature of the inverter is high, it is recommended to reduce the temperature of the inverter and strengthen cooling and ventilation; 2. Increase the frequency of regular maintenance of inverter fans, air ducts, etc., so as to improve the operating environment of the inverter, so that the inverter ...

Some methods when debugging Yaskawa servo drives In the Yaskawa servo system under low rigidity (1-4) load, the inertia ratio is very important, from the perspective of the synchronous belt structure, the stiffness is about 1-2 (or even less than 1), at this time, the inertia ratio can not be automatically tuned, it must be ...

PN000 function selection N.0010 (setting value) 0th position: set the direction of rotation of the motor; Set "1" to change the rotation of the motor in reverse. 1st position: Set the control mode to: "1" position control mode. PN200 Command Pulse Input Mode Function Selection N.0101 (Set Value) "1" Positive ...

　　At 10 a.m. on December 23, 2022, Yaskawa Electric held an online new product launch conference and officially released the next-generation servo products Σ-X series and the new data collection controller YRM-X. Advanced and optimized motion performance and digital solutions starting with servo are the two major features of this new product.

1. Determine mechanical specifications, load, rigidity and other parameters; 2. Confirm the action parameters, stroke, accuracy, acceleration and deceleration time, cycle, moving speed, etc.; 3. Select motor inertia, load inertia, motor axis conversion inertia, and rotor inertia; 4. Select the motor back ...

1. High-voltage inverter will develop in the direction of high power, miniaturization and lightweight. 2. The high-voltage inverter will develop in the direction of direct device high voltage and multiple superposition (device series and unit series). 3. New power semiconductors with higher voltage and higher current ...

Yaskawa Electric, one of the world's largest manufacturers of industrial robots, announced a 150% year-on-year increase in net profit for the six months ended Sept. 30. The Japan company announced that the company reported a profit for the quarter due to the demand for its industrial robots in China, Japan and United States.
