济南变频器维修：变频器在使用的时候不免就会出现一些这样那样的小故障，今天，就与大家一起分析一下都会有哪些常见的问题，以及解决办法。
Jinan Inverter Maintenance: Inverter in use will inevitably appear some of these and other small failures, today, we will work with you to analyze what common problems, and solutions.
1、按下运行键，电机不转。
1. Press the operation key and the motor will not turn.
1)运行方式设定错误，即运行方式在外控端子情况下，用面板操作起动或运行方式操作器情况下，用外控端子进行起动。
1) Error in setting operation mode, i.e. when the operation mode is in the case of external control terminal, when the panel operation is used to start or when the operation mode operator is in the case, the external control terminal is used to start.
2)频率指令太低或没设定。
2) The frequency instruction is too low or not set.
3)外围接线错误，如二线制、三线制接线及有关参数设定有误。
3) Peripheral wiring errors, such as two-wire system, three-wire system wiring and related parameters setting errors.
4)多功能输入端子设定错误。
4) Error setting of multi-function input terminal.
5)变频器在故障保护状态。
5) Frequency converter in fault protection state.
2、机械有振动或轰鸣声
2. Mechanical vibration or roar
1)机械系统的振动频率与载波发生共振，调整载波，避开共振点。
1) The vibration frequency of the mechanical system resonates with the carrier wave, and the carrier wave is adjusted to avoid the resonance point.
2)机械系统的振动频率与变频器输出频率发生共振。
2) The vibration frequency of mechanical system resonates with the output frequency of frequency converter.
a.设置跳跃功能，避开共振点。
A. Set up jump function to avoid resonance point.
b.在电机底板上设置防震橡胶。
B. Install shock-proof rubber on the motor floor.
3、电机减速太慢
3. Motor deceleration is too slow
1)减速时间设定太长，减小减速时间。
1) The deceleration time is set too long to reduce the deceleration time.
2)加装制动电阻。
2) Install brake resistance.
3)加直流制动。
3) Add DC brake.
4、电机过热
4. Motor overheating
1)负载太大，实际力矩已超过马达的设定转矩，建议增大马达容量。
1) The load is too large, the actual torque has exceeded the set torque of the motor, so it is suggested to increase the capacity of the motor.
2)环境温度太高，在温度较高的环境下，电机会烧坏请降低电机周围温度。
2) The ambient temperature is too high. In the high temperature environment, the motor will burn out. Please lower the ambient temperature of the motor.
3)电机的相间耐压不足。
3) insufficient inter-phase voltage withstanding of motors.
5、风机起动时，变频器检出过流失速
5. When the fan starts, the frequency converter detects the excessive loss speed.
1)起动时，风机处于转动无序状态，请设置起动时直流制动。
1) When starting, the fan is in disorder of rotation. Please set DC brake when starting.
2)已设定起动时直流制动，请增大直流制动值。
2) DC brake has been set when starting, please increase the value of DC brake.
6、参数不能设定
6. Parameters cannot be set
1)密码锁定，请解密后再设定。
1) The password is locked. Please decrypt it and set it again.
2)变频器运行中。
2) Frequency converter in operation.
3)接插件连接异常，数字操作器通讯异常，断电后将操作器取下，重装上去试一下。
3) The connection of the plug-in is abnormal, and the communication of the digital operator is abnormal. After power failure, remove the operator and reinstall it for a try.
