Inverter Basic Parameters Debugging

Many converter function parameters, in general, there had dozens or even hundreds of parameters for the user to choose. Practical application, there is no need for each parameter set and debugging, as long as the majority of using factory settings can be. But due to some parameters and actual use of a great relationship, and some are still interconnected, Therefore, we must consider the actual settings and debug . Because of the type of converter function differences, and functional parameters of the same name is also inconsistent, as described convenience, Based on Fujitsu Inverter basic parameters name as an example. As the basic parameters of the different types of almost all of the inverter, we can do they jump.

1 Increase in deceleration time

Acceleration time is the output frequency from 0 up to the maximum frequency the time required, deceleration time is from the largest decline in the frequency of 0 required time. Usually frequency signal set up, down to determine deceleration time. Motor speed up the time required to set restrictions on the frequency rate of increase to prevent over-current, restricted decelerating rate dropped to prevent over-voltage. Accelerate time setting requirements : Current restrictions would accelerate the inverter over-current capacity below not to cross the loss of speed caused converter trip; deceleration time set points are : to prevent smoothing circuit voltage is too large, not renewable so over-voltage converter stall trip. Acceleration and deceleration time under load calculation, but in debugging often adopted by the load and experience first set longer acceleration and deceleration time through, stopping to observe whether motor current and voltage alarm; then accelerating and decelerating gradually shorten the time set, to the non-functioning alarm occurred to the principle of repeat several times, we can determine the best acceleration and deceleration time.

2 Torque upgrade

Torque is known as compensation for compensation from the motor stator windings resistance caused by the low speed torque reduction, and the low-frequency range of f / V increases method. Set to automatic, will accelerate the upgrade automatic voltage to compensate for starting torque, the motor to accelerate smoothly. Using manual compensation, in accordance with the load characteristics, in particular the starting load characteristics can be selected through the test better curve. For variable torque load, as there will be a poor choice of low output voltage is too high, and the waste of energy, there will even load motor starter when current, and speed falters

phenomenon.

3 Electronic Thermal Overload Protection

The function of the motor overheating protection setup, It is within the CPU frequency converter operating under the current value and frequency of the motor calculated temperature rise, for the protection of overheating. This function only applies to "drag a" occasion, and "a number of tractors," should be in the retrofitting Motors thermal relay.

Electronic thermal protection settings (%)=[ motor rated current (A) / Rated output current converter (A)] × 10 0%.

4 Frequency restrictions

That the inverter output frequency, amplitude threshold. Frequency limitation is to prevent the misoperation or external frequency setting signal failure, which leads to the output frequency is too high or too low. prevent damage to the equipment of a protective function. The application on the actual situation can be set. This function may also be used for the speed limit, if the conveyor belt, due to transportation of materials is not much, To reduce the mechanical and wear belts, use inverter-driven, and will limit frequency inverter settings for a particular frequency, This would enable the conveyor belt running on a fixed, low speed work.

5 Frequency Offset

Some deviation is known as the frequency or frequency deviation settings. When their use is by the external frequency analog signal (voltage or current) settings, This function can be adjusted frequency signal set at the lowest level of the output frequency, as illustrated in figure 1. When some frequency transducer signal set for 0%, the error values role of the range 0 ~ HBT, Some converter (such as electricity for homes, Sanken) may also bias polarity settings. Debugging in frequency when the signal is set at 0%, the inverter output frequency is 0 Hz, for xHz. At this time it will be set to the frequency offset the negative xHz will enable inverter output frequency is 0 Hz.

6 Set the frequency signal gain

This function only with external analog signal frequency setting was effective. It is used to cover external set voltage and signal transducer voltage (+10 v) the inconsistencies; facilitating simulation setting signal voltage options set, when the analog input signal for a maximum (10 v, 5v or 20mA), the output can be obtained f / V graphics frequency and percentage of this parameter can be set; If external signals

set to 0-5v, if the inverter output frequency of 50Hz ~ 0. Gain signal will be set to 200% can be.

7 Torque limit

Can be divided into driving torque and braking torque limit restricted. It is based on inverter output voltage and current values, the CPU torque, can increase its deceleration constant speed operation and the impact of load recovery characteristics are significantly improved. Torque limit function for automatic acceleration and deceleration control. Assuming acceleration and deceleration time is less than inertia load time, the motor can be guaranteed in accordance with the torque settings automatically accelerate and decelerate.

Driving torque functions provide a powerful starting torque, in steady state operation, the torque control motor functions will turn bad, Motor torque and will limit the maximum value set, when suddenly increased load torque, or even in accelerated time setting off a short time, Inverter is unlikely to cause tripping. Accelerating time setting off a short time, motor torque will not exceed the maximum values. Drivers of large start-up torque advantageous to set to 80 ~ 100% more properly.

Braking torque setting numerical smaller, the greater the braking force, acceleration and deceleration for emergency occasions, If braking torque setting numerical Assembly set off alarm occurred pressure phenomena. If braking torque set at 0%, added to the main capacitor will enable the renewable total closer to 0, so that the slowdown in the motor, the non-use of braking deceleration resistance can not turn to stop tripping. But in some loads, such as brake torque set at 0%, the slowdown will be temporary idling, Starting inverters, repeatedly, the current significant fluctuations serious converter Trip will be to attract attention.

8 Acceleration and deceleration mode selection

Known as the acceleration and deceleration curves choice. General converter is linear, nonlinear, and three S curve, usually will choose linear curve; Nonlinear curve applies to variable torque load, such as fan; S curve in constant torque load, slowdown in the rate of change is slow. Settings can load torque characteristic curve corresponding options, but there are exceptions. Debugging a writer in Taiwan Boiler fan of inverters, the first acceleration and deceleration curves choice nonlinear curve, get going on the trip inverter operation, adjusting to change many parameters without results, later renamed the S-curve after the normal. It is the reason : Starting op fan as

flue gas flow on its own rotation and inversion as a negative load, This selection of the S-curve, starting just when the frequency increased slowly, in order to avoid a trip to the converter, Of course, this is not starting against DC converter brake function of the method used.

9 Torque Vector Control

Vector Control is based on the theory that : asynchronous motors and DC motors have the same mechanism of torque. Vector control of the stator current is divided into the current and magnetic torque current, respectively control, while both the synthesis of the stator current output to the motor. Therefore, based on the principle of DC motors available with the same performance. Using torque vector control function, motor in various operating conditions can output maximum torque, especially in the low-speed motor running regional.

Now almost all of the inverter by using feedback vector control, As the transducer based on the size and the load current phase of deterioration in compensation, and the motor is the mechanical characteristics are strong, For most occasions have been able to meet the requirements without the external converter installed speed feedback circuit. This function settings, according to the actual situation in the effective and ineffective one can choose.

With the transfer function is poor compensation control, whose role is to compensate by load fluctuations caused by the speed deviation can be added corresponding to the load current to the frequency difference. The main function for positioning control.

10 Energy-saving control

Fans, pumps are reduced torque load, with the speed of that decline, load torque and speed proportional to the square of decreases, and control functions with energy-saving design of the inverter exclusive V / f mode, This model can be improved motor and the inverter efficiency, may reduce the load current automatic converter output voltage, so as to achieve energy-saving purposes, in accordance with the specific circumstances set to be valid or invalid.

I need Explained 9、10 these two parameters are very advanced, but some users to upgrade equipment, not simply the opening of these two parameters, that is, after the opening of inverter frequent tripping, suspended after all normal. It is because : (1) original parameters of the inverter and the motor request for the electrical parameters that much difference. (2) for the creation of inadequate understanding of the

functional parameters, such as energy-saving control function can only be used for V / f controlled manner, not for vector control approaches. (3) the opening of the vector control methods, but no electrical parameters of the manual and automatic settings to read, read or improper methods.

Constant pressure water supply frequency changer The transistor frequency changer not only overcame has formerly exchanged velocity modulation many shortcomings, moreover the velocity modulation performance might compare favorably with the direct current motor velocity modulation performance. The three-phase asynchronous motor has the service to be convenient, merit and so on price small advantage, power and rotational speed adapt breadth, its frequency conversion velocity modulation technology in the miniaturization, the low cost and the redundant reliable aspect holds the obvious superiority. To the end of the 80's, the alternating current machine frequency conversion velocity modulation technology rapidly develops into a mature technology, it will supply the alternating current machine the labor frequency alternating current supply to turn direct current after the diode rectification, again by component and so on IGBT or GTR module counter will turn the alternating current supply which the frequency might move, will drive the electrical machinery by this power source to move under the speed change condition, and automatic suitable strain load condition. After it changed in the traditional industry the electrical machinery to start only can by the rated power, decide the rotational speed the sole movement way, thus achieved the energy conservation goal.

变频器参数基本设置

变频器参数基本设置 变频器应用领域涉及到钢铁行业,化工行业,汽车行业,机床行业,电机机械行业,食品行业,造纸行业,水泥行业,矿业行业,石油行业,工厂建筑等,它促进企业实现了自动化,节约了能源,提高了产品质量和合格率以及生产率,延长了设备使用寿命。通过变频器的功能参数的设置调试,就可以实现相应的功能,一般都有数十甚至上百个参数供用户选择,在实际应用中,没必要对每一参数都进行设置和调试,多数只要采用出厂设定值即可。但有些参数由于和实际使用情况有很大关系,且有的还相互关联,因此要根据实际进行参数的设定和调试。变频器调试的好坏决定了变频器运行的稳定性、应用效果以及使用寿命等,最终关系到企业经济效益的大小,调好了可能大大节约费用,调不好可能损失惨重。以下是作者在普传变频器使用中的经验总结,希望能供其他用户参考,使变频器能更好地推广使用,为企业带来更大的经济效益。 1 变频器调试的步骤 变频器能否成功地应用到各种负载中,且长期稳定地运行,现场调试很关键,必须按照下述相应的步骤进行。 1.1 变频器的空载通电检验 1)将变频器的电源输入端子经过漏电保护开关接到电源上。 2)将变频器的接地端子接地。 3)确认变频器铭牌上的电压、频率等级与电网的是否相吻合,无误后送电。 4)主接触器吸合,风扇运转,用万用表AC 挡测试输入电源电压是否在标准规范内。5)熟悉变频器的操作键盘键, 以普传科技变频器为例: FWD为正向运行键,令驱动器正向运行; REV为反向运行键,令驱动器反向运行; ESC/DISPL为退出/显示键,退出功能项的数据更改,故障状态退出,退出子菜单或由

功能项菜单进入状态显示菜单; STOP/RESET 为停止复位键,令驱动器停止运行,异常复位,故障确认; PRG为参数设定/移位键; SET 为参数设定键,数值修改完毕保存,监视状态下改变监视对象; ▲▼为参数变更/加减键,设定值及参数变更使用,监视状态下改变给定频率; JOG为寸动运行键,按下寸动运行,松开停止运行,不同变频器操作键的定义基本相同。6)变频器运行到50 Hz,测试变频器U V W三相输出电压是否平衡。 7)断电完全没显示后,接上电机线。 1.2 变频器带电机空载运行 1)设置电机的基本额定参数,要综合考虑变频器的工作电流。 2)设定变频器的最大输出频率、基频、设置转矩特性。v/f类型的选择包括最高频率、基本频率和转矩类型等项目。最高频率是变频器—电动机系统可以运行的最高频率,由于变频器自身的最高频率可能较高,当电动机容许的最高频率低于变频器的最高频率时,应按电动机及其负载的要求进行设定。基本频率是变频器对电动机进行恒功率控制和恒转矩控制的分界线,应按电动机的额定电压进行设定。转矩类型指负载是恒转矩负载还是变转矩负载。用户根据变频器使用说明书中的v/f类型图和负载特点,选择其中的一种类型。通用变频器均备有多条v/f曲线供用户选择,用户在使用时应根据负载的性质选择合适的v/f 曲线。为了改善变频器启动时的低速性能,使电机输出的转矩能满足生产负载启动的要求,要调整启动转矩。在异步电机变频调速系统中,转矩的控制较复杂。在低频段,由于电阻、漏电抗的影响不容忽略,若仍保持v/f为常数,则磁通将减小,进而减小了电机的输出转矩。为此,在低频段要对电压进行适当补偿以提升转矩。一般变频器均由用户进行人工设定补偿。普传变频器则为用户提供两种选择,即42种v/f提升方式,自动转矩提升。

变频器参数如何设置

变频器的设定参数较多,每个参数均有一定的选择范围,使用中常常遇到因个别参数设置不当,导致变频器不能正常工作的现象,因此,必须对相关的参数进行正确的设定。 1 、控制方式: 即速度控制、转距控制、PID 控制或其他方式。采取控制方式后,一般要根据控制精度进行静态或动态辨识。 2 、最低运行频率: 即电机运行的最小转速,电机在低转速下运行时,其散热性能很差,电机长时间运行在低转速下,会导致电机烧毁。而且低速时,其电缆中的电流也会增大,也会导致电缆发热。 3 、最高运行频率: 一般的变频器最大频率到60Hz ,有的甚至到400 Hz ,高频率将使电机高速运转,这对普通电机来说,其轴承不能长时间的超额定转速运行,电机的转子是否能承受这样的离心力。 4 、载波频率: 载波频率设置的越高其高次谐波分量越大,这和电缆的长度,电机发热,电缆发热变频器发热等因素是密切相关的。 5 、电机参数: 变频器在参数中设定电机的功率、电流、电压、转速、最大频率,这些参数可以从电机铭牌中直接得到。 6 、跳频: 在某个频率点上,有可能会发生共振现象,特别在整个装置比较高时;在控制压缩机时,要避免压缩机的喘振点。 变频器参数设置(二) 变频器功能参数很多,一般都有数十甚至上百个参数供用户选择。实际应用中,没必要对每一参数都进行设置和调试,多数只要采用出厂设定值即可。 一、加减速时间 加速时间就是输出频率从0 上升到最大频率所需时间,减速时间是指从最大频率下降到0 所需时间。通常用频率设定信号上升、下降来确定加减速时间。在电动机加速时须限制频率设定的上升率以防止过电流,减速时则限制下降率以防止过电压。 加速时间设定要求:将加速电流限制在变频器过电流容量以下,不使过流失速而引起变频器跳闸;减速时间设定要点是:防止平滑电路电压过大,不使再生过压失速而使变频器跳闸。加减

变频器调试步骤及注意事项

变频器检测调试的项目及注意事项 (以爱默生变频器为例) 一、变频器输出端与电动机电源线未连接前 (一)上电前的检查项目及内容 1.检查屏体和变频器的外观(包括盘面、面板安装的附属设备),设备是否受损或缺失。 2.检查主接线是否正确、各连接部位是否可靠、有无松动。 3.检查屏内和变频器内各端子及端子排的接线是否正确、可靠。 4.检查附属设备(包括变送器、继电器)的安装及接线是否正确、可靠。 (二)操作面板控制方式下的调试 1.合上电源侧主回路空开,合上控制电源空开,屏面上的“控制电源”指示灯应发平光。 2.将功能码F0.00和F0.03均设置为“0”(选择操作面板增加键“▲”、减少键“▼”进行频率调节和操作面板运行命令通道),然后逐一设置相关功能码的参数,核对无误后进行确认,操作面板上的“运行命令通道”指示灯应发平光。 3.按下面板的运行键RUN,变频器随即进入运行状态。屏面上的“运行状态”指示灯和操作面板上的“运行状态”指示灯均应发平光,测量端子排的N36、N37两端子应通路。 4.观察起动过程中操作面板数字显示的频率及上升速度是否正常,与设置值是否一致。 5.通过面板的增加键“▲”、减少键“▼”进行频率调节。观察操作面板数字显示的频率,测量模拟输出信号的变化与频率的显示是否一致。 6.将端子排的N11与N00两个端子用导线短接,以此模拟变频器综合故障,屏面上的“变频器综合故障”指示灯应发平光,屏面上的“运行状态”指示灯和操作面板上的“运行状态”指示灯均应熄灭,端子排的N38、N39两端子应通路。 7.检查变频器瞬停自动跟踪起动或瞬时停电不停机的功能是否可靠。 8.按下操作面板上的停机键STOP,变频器应由运行状态转为停机状态。 进行上述检查,主要是检验变频器的功能设置及接线的正确性。 (三)端子控制(VCI给定)“本地”操作方式下的调试 1.将功能码F0.00设置为“3”(选择VCI给定方式),将F0.03设置为“1”(选择端子运行命令通道),其它已设置的功能码参数不变,核定无误后进行确认。在VCI给定状态下,操作面板上的“运行命令通道”指示灯不发光。 2.将控制方式选择开关置于“本地”位置,分别按下屏面上的起动按钮、机旁按钮盒的起动按钮,变频器均应进入运行状态。 3.通过屏面安装的速度调节电位器进行调节,观察操作面板上数码管显示的频率,测量模拟输出信号的变化与频率的显示是否一致。 4.分别按下屏面上的停机按钮、机旁按钮盒的急停按钮,变频器均应由运行状态转为停机状态。 (四)端子控制(CCI给定)“远控”操作方式下的调试 1.将功能码F0.00设置为“4”(选择CCI给定方式),其它已设置的功能码参数不变,核定无误后进行确认。在CCI给定状态下,操作面板上的“运行命令通道”指示灯不发光。
