Common fault codes for Yaskawa servo drives

1. When the oscilloscope checks the current monitoring output of the driver, it is found that it is all noise and cannot be read; Cause of failure: The current monitoring output is not isolated from the AC power supply (transformer). Solution: It can be detected and observed with a DC voltmeter. 2. Motor ...

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) Check and remove the dust and debris on the motor; (2) Check whether the voltage, frequency and power supply voltage and frequency on the nameplate of the motor are consistent with the actual situation, and whether the connection method is correct. (3) Use the insulation resistance meter to measure the phase and phase and phase of the motor winding.

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. ...

A.F10: Power line is out of phase (the low voltage state of one phase of R, S, and T phases lasts for more than 1 second in the state of the main circuit power supply ON) Cause: Poor wiring of three-phase wires The three-phase power supply is unbalanced Single-phase AC power input is not set (Pn00E ...

There are three types of general speed measurement methods: M method, T method, and M/T method. 1. M Method: (1) M method: open a time window, count the number of encoder pulses in this time window, the faster the speed, of course, the more pulses are counted for the time window. (2) Angular velocity ...

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 ...

The fault code is CF refers to Control Failure, which reaches the torque limit for more than 3 seconds in the deceleration stop (no PG vector control mode) Possible reasons are: The motor parameters are not set correctly The set value of the torque limit is too small The load inertia is relatively ...

1. Yaskawa servo alarm A840 (A84) is: encoder data error alarm. A.84 Common causes of alarm are: 1. Excessive mechanical vibration 2. High-frequency noise in the application environment 3. Servo motor inlet water inlet oil, dust, etc 4. The driver is faulty ...

Yaskawa servo drive alarm code 710 is overload (large load), the motor is overloaded for a few seconds to tens of seconds. Solution(s): 1. Change the mechanism, or the acceleration and deceleration mechanism. 2. Change the motor. 3. Exclusion order: (1) The load is really too large ...

1. The inverter shows that SC refers to the drive fault. 2. Cause of failure: 1. The output side of the inverter is interphase or short circuit to the ground. 2. The inverter module is damaged. 3. Handling method: 1. Remove the load, power on normally and turn on the machine, check if there is a three-phase ...

1. Fan With the continuous development of industry, the application of fans is becoming more and more extensive, especially in the chemical, stone and textile industries. However, there is a general problem of over-air volume in the design of the fan, and throttling is generally used when the air volume needs to be adjusted, that is, the damper is adjusted.

Fault analysis: the power line is out of phase Fault cause: Yaskawa servo motor factory is the default AC three-phase 200V power input, when connected to the single-phase 220V power supply, it will cause the servo driver to alarm A.F10 when the power is turned on. Troubleshooting: Set the servo parameter Pn00B to n.▢1▢ ...

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 ...

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 ...

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 ...

There are three main starting methods of three-phase asynchronous: direct start, traditional decompression start and soft start. Direct start, also called full pressure start. Decompression starting is to reduce the voltage on the stator winding during starting, and then restore the voltage to the rated after starting. Include...
