6RA7075-6DS22-0 常见故障及维修

（一）常见故障类型 6RA7075-6DS22-0

6RA7075-6DS22-0 电气故障

无励磁电压：可能是励磁电路部分出现断路、元件损坏等情况导致。

烧保险：电路中可能存在短路，例如元件被击穿等原因，造成电流过大烧保险。

模块炸：模块工作时可能由于过电压、过电流、散热不良等因素导致损坏爆炸。

运转速度不稳定：这可能与速度环参数未·佳化、KV系数太大、电源电压不稳定或者调速器内部元件性能不良有关。

烧可控硅（晶闸管）：过流、过压、散热问题或者元件自身质量问题都可能造成可控硅烧毁。

功能故障 6RA7075-6DS22-0

直流调速装置无显示：可能是电源部分故障，如电源板损坏，无法为显示模块提供正常供电。

运转速度不连贯：这或许是因为调速器内部信号传输不畅，或者是电机与调速器之间的连接存在问题。

高速不稳定、低速不稳定：速度环的参数设置不合理、电机负载变化较大或者调速器自身的性能在不同速度下表现不一致都可能引起这种故障。

启动合闸跳保险：启动瞬间电流过大，可能是电机故障（如绕组短路）或者调速器内部存在短路故障导致。

运转不出力：可能是功率模块输出功率不足、电机故障或者调速器与电机之间的匹配存在问题。

报励磁故障：励磁电路出现问题，例如励磁线圈故障、励磁控制电路故障等。

优化通不过：调速器的参数设置不合理，无法满足优化条件，可能是电机参数设置错误或者调速器内部的控制算法要求未得到满足。

启动报代码故障：不同的故障代码对应不同的故障原因，如F006欠电压故障、F030电枢电流过大导致脉冲封锁等常见报警代码所对应的故障情况。

超速：速度控制环节出现问题，如速度给定信号异常、速度反馈信号缺失或者调速器内部控制速度的程序出错。

带负载报故障：负载过大超过调速器的承受能力，或者负载的特性与调速器不匹配，也可能是调速器在带载情况下某些元件工作不正常。

6RA7075-6DS22-0 Common faults and repairs

(1) Common fault types

Electrical failure

No excitation voltage: It may be caused by an open circuit in the excitation circuit, component damage, etc.

Fuse burning: There may be a short circuit in the circuit, such as component breakdown, etc., causing excessive current to burn the fuse.

Module explosion: The module may be damaged and explode due to overvoltage, overcurrent, poor heat dissipation and other factors during operation.

Unstable operating speed: This may be related to unoptimized speed loop parameters, too large KV coefficient, unstable power supply voltage, or poor performance of the internal components of the speed regulator.

Burning the thyristor (thyristor): Overcurrent, overvoltage, heat dissipation problems or component quality problems may cause the thyristor to burn.

Functional failure

There is no display on the DC speed control device: it may be that the power supply part is faulty, such as the power board is damaged and cannot provide normal power supply to the display module.

Inconsistent running speed: This may be due to poor signal transmission within the speed regulator, or there may be a problem with the connection between the motor and the speed regulator.

High-speed instability and low-speed instability: This fault may be caused by unreasonable parameter settings of the speed loop, large changes in motor load, or inconsistent performance of the speed regulator itself at different speeds.

Fuse tripping at startup and closing: The current at startup is too large, which may be caused by a motor failure (such as a winding short circuit) or a short circuit fault inside the speed regulator.

Failure to operate: It may be that the output power of the power module is insufficient, the motor is faulty, or there is a problem with the matching between the speed controller and the motor.

Excitation fault: There is a problem with the excitation circuit, such as excitation coil failure, excitation control circuit failure, etc.

Optimization failed: The parameter setting of the speed regulator is unreasonable and cannot meet the optimization conditions. It may be that the motor parameter setting is wrong or the control algorithm requirements inside the speed regulator are not met.

Startup alarm code fault: Different fault codes correspond to different fault causes, such as F006 under-voltage fault, F030 excessive armature current causing pulse blockage and other common alarm codes.

Overspeed: There is a problem in the speed control link, such as an abnormality in the speed given signal, missing speed feedback signal, or an error in the internal speed control program of the governor.

Fault reporting under load: The load is too large and exceeds the bearing capacity of the speed regulator, or the characteristics of the load do not match the speed regulator, or it may be that some components of the speed regulator are not working properly under load.
