Attention to the wiring of the inverter 1. The inverter itself has strong electromagnetic interference, which will interfere with the work of some equipment, so we can add a cable sleeve to the output cable of the inverter. 2. The control line in the inverter or control cabinet is at least 100mm away from the power cable, etc. ...

1 Disadvantages of choosing too high a voltage level Choosing too high a voltage level results in too high an investment and a long payback period. With the increase of the voltage level, the insulation of the motor must be improved, so that the price of the motor increases. The increase of the voltage level increases the number of series connections of power semiconductor devices in the inverter, ...

1. Enter the parameter menu, select the "Motor Current" item, and set the rated current of the motor In 2. Select the "Overload Protection" item to enter a form: select to enter the overload fixed value multiplier. The overload fixed value magnification range is 100-700%, just enter the number between 100 and 700.

1. First of all, connect the terminal block of Yaskawa servo B1B2, in which the B1 terminal receives the power supply and the B2 terminal receives the signal; 2. Then, connect the terminal block of Yaskawa servo B1B2, wherein B1 terminal receives power supply, and B2 terminal receives signal; 3. After the wiring is completed, ...

Yaskawa manipulator specification It must be trained before the job and can only be operated after qualifying. Untrained personnel are not allowed to operate the manipulator. BEFORE OPENING, CHECK WHETHER THE AIR SOURCE OF THE MANIPULATOR IS ENERGIZED, ADJUST THE AIR PRESSURE OF THE PRESSURE VALVE BETWEEN 0.6MPA AND 0.8MPA, AND CHECK WHETHER THE VOLTAGE IS NORMAL. What is ...

1. Failure of mechanical system (1) The common fault phenomena and causes of mechanical systems are as follows 1. Due to poor lubrication or lubrication system failure, the rotating parts of the parts are seriously heated and worn or the shaft is held, resulting in the destruction of the parts of the rolling or sliding parts. 2 ...

The switching power supply is damaged Switching power supply damage is the most common fault of many inverters, usually caused by short circuit in the load of switching power supply, in the design of switching power supply circuits of many inverters, Yaskawa inverter is relatively successful. OH failure Old...

09. Robot oil leakage? Cause: 1. Improper maintenance; 2. Corrosive parts damage, etc. Solution: Check the location of the oil leak and confirm the parts caused by the oil leak. It is possible to accurately determine the parts caused by oil leakage by checking drawings, etc. 10. Robot ...

Analysis of the fault code of Yaskawa inverter, for reference only: OC Overcurrent The output current of the inverter exceeds the overcurrent detection value · GF grornd Favlt Grounding The ground current on the output side of the inverter exceeds 50% of the rated output current of the inverter ...

1. Specifications and parameters of the motor The inverter drives the motor during use, so the inverter can be selected from the perspective of the motor to select the model and specification. First of all, we must first understand the specifications and parameters of the motor. You can use Yaskawa inverter ...

1, Maybe the connection of the external resistor is bad, falling off and disconnecting will cause an alarm, we can check the wiring. 2. It may be that the jumper wire of the resistor connection terminal B2-B3 falls off, and then check if the jumper wire falls off. 3. It may be that the resistor capacity ...

1. Compressor load Compressors are also widely used loads. Low-pressure compressors are widely used in various industrial sectors, and high-pressure large-capacity compressors are widely used in steel (such as oxygen generators), mines, fertilizers, and ethylene. The use of frequency conversion speed regulation, all bring small starting current, ...

1. It may be that the capacity of the servo unit does not match the capacity of the servo motor. 2. It may be that the servo unit is faulty. 3. It may be outside the range of parameter settings. 4. It may be that the set value of the electronic gear ratio is outside the set range. ...

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. ...

1. The acceleration/deceleration time constant is too small. Increase the acceleration/deceleration time constant. 2. The torque limit value set by the controller is too small. Increase the torque limit value. 3. The motor cannot start due to the insufficient torque caused by the drop in power supply voltage. 4. Check the power capacity. ...

1. Different control methods Stepper motor: The rotation angle is controlled by controlling the number of pulses, and one pulse corresponds to one step angle. Servo motor: The angle of rotation is controlled by controlling the length of the pulse time. 2. The workflow is different Stepper Motor: Stepper ...

Yaskawa servo motor, also known as YASKAWA Yaskawa servo motor, is an automatic control system, which can control the position, orientation, status and other outputs of the target, and can change with the change of the target input value (or given value). It can be divided into AC servo motor and DC servo motor ...

Yaskawa inverter Uv1 fault name: main circuit undervoltage If the operation command is not entered (the inverter is stopping), the following conditions occur. 1. The DC voltage of the main circuit is lower than the set value of L2-05 (the detection value of the undervoltage (UV) of the main circuit). 2. 200V class: about 190V ( ...

1. The input power of Yaskawa drive drops, resulting in an internal undervoltage alarm 2. The drive power supply failure causes Yaskawa Drive to detect an undervoltage fault 3.
