1、蒂森电梯配件的变频器调试的基本步骤核心提示：一、蒂森电梯配件的变频器带电机空载运行1.设置电机的功率、极数,要综合考虑蒂森电梯配件的变频器的工作电流。2.设定蒂森电梯配一、蒂森电梯配件的变频器带电机空载运行1.设置电机的功率、极数,要综合考虑蒂森电梯配件的变频器的工作电流。 2.设定蒂森电梯配件的变频器的最大输出频率、基频、设置转矩特性。通用蒂森电梯配件的变频器均备有多条VPf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VPf曲线。如果是风机和泵类负载,要将蒂森电梯配件的变频器的转矩运行代码设置成变转矩和降转矩运行特性。为了改善蒂森电梯配件的变频器启动时的低速性能,使电机输出的转矩能
2、满足生产负载启动的要求,要调整启动转矩。在蒂森电梯配件的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VPf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。一般蒂森电梯配件的变频器均由用户进行人工设定补偿。 3.将蒂森电梯配件的变频器设置为自带的键盘操作模式,按运行键、停止键,观察电机是否能正常地启动、停止。 4.熟悉变频器运行发生故障时的保护代码,观察热保护继电器的出厂值,观察过载保护的设定值,需要时可以修改。蒂森电梯配件的变频器的使用人员可以按变频器的使用说明书对变频器的电子热继电器功能进行设定。当
3、变频器的输出电流超过其容许电流时,变频器的过电流保护将切断变频器的输出。因此,变频器电子热继电器的门限最大值不超过变频器的最大容许输出电流。 二、带载试运行1.手动操作变频器面板的运行停止键,观察电机运行停止过程及蒂森电梯配件的变频器的显示窗,看是否有异常现象。 2.如果启动P停止电机过程中蒂森电梯配件的变频器出现过流保护动作,应重新设定加速P减速时间。电机在加、减速时的加速度取决于加速转矩,而蒂森电梯配件的变频器在启、制动过程中的频率变化率是用户设定的。若电机转动惯量或电机负载变化,按预先设定的频率变化率升速或减速时,有可能出现加速转矩不够,从而造成电机失速,即电机转速与蒂森电梯配件的变频器
4、输出频率不协调,从而造成过电流或过电压。因此,需要根据电机转动惯量和负载合理设定加、减速时间,使蒂森电梯配件的变频器的频率变化率能与电机转速变化率相协调。检查此项设定是否合理的方法是先按经验选定加、减速时间进行设定,若在启动过程中出现过流,则可适当延长加速时间;若在制动过程中出现过流,则适当延长减速时间。另一方面,加、减速时间不宜设定太长,时间太长将影响生产效率,特别是频繁启、制动时。 3.如果蒂森电梯配件的变频器在限定的时间内仍然保护,应改变启动P停止的运行曲线,从直线改为S形、U形线或S形、反U形线。电机负载惯性较大时,应该采用更长的启动停止时间,并且根据其负载特性设置运行曲线类型。 4.
5、如果蒂森电梯配件的变频器仍然存在运行故障,应尝试增加最大电流的保护值,但是不能取消保护,应留有至少10%20%的保护余量。 5.如果蒂森电梯配件的变频器运行故障还是发生,应更换更大一级功率的变频器 6.如果蒂森电梯配件的变频器带动电机在启动过程中达不到预设速度,可能有两种情况:(1)系统发生机电共振,可以从电机运转的声音进行判断。采用设置频率跳跃值的方法,可以避开共振点。一般蒂森电梯配件的变频器能设定三级跳跃点。VPf控制的变频器驱动异步电机时,在某些频率段,电机的电流、转速会发生振荡,严重时系统无法运行,甚至在加速过程中出现过电流保护使得电机不能正常启动,在电机轻载或转动惯量较小时更为严重。
6、普通变频器均备有频率跨跳功能,用户可以根据系统出现振荡的频率点,在VPf曲线上设置跨跳点及跨跳宽度。当电机加速时可以自动跳过这些频率段,保证系统能够正常运行。 (2)电机的转矩输出能力不够,不同品牌的变频器出厂参数设置不同,在相同的条件下,带载能力不同,也可能因变频器控制方法不同,造成电机的带载能力不同;或因系统的输出效率不同,造成带载能力会有所差异。对于这种情况,可以增加转矩提升量的值。如果达不到,可用手动转矩提升功能,不要设定过大,电机这时的温升会增加。如果仍然不行,应改用新的控制方法,比如蒂森电梯配件的变频器采用VPf比值恒定的方法,启动达不到要求时,改用无速度传感器空间矢量控制方法,它
7、具有更大的转矩输出能力。对于风机和泵类负载,应减少降转矩的曲线值。 三、蒂森电梯配件的变频器与上位机相连进行系统调试在手动的基本设定完成后,如果系统中有上位机,将变频器的控制线直接与上位机控制线相连,并将蒂森电梯配件的变频器的操作模式改为端子控制。根据上位机系统的需要,调定变频器接收频率信号端子的量程05V或010V,以及变频器对模拟频率信号采样的响应速度。如果需要另外的监视表头,应选择模拟输出的监视量,并调整蒂森电梯配件的变频器输出监视量端子的量程。四、蒂森电梯配件的变频器的空载通电检验1将蒂森电梯配件的变频器的接地端子接地。 2将蒂森电梯配件的变频器的电源输入端子经过漏电保护开关接到电源上
8、。 3检查蒂森电梯配件的变频器显示窗出厂显示是否正常,如果不正确,应复位,否则要求退换。 4熟悉蒂森电梯配件的变频器的操作键。一般的变频器均有运行(RUN)、停止(STOP)、编程(PROG)、数据P确认(DATAPENTER)、增加(UP、)、减少(DOWN、)等6个键,不同变频器操作键的定义基本相同。此外有的变频器还有监视(MONITORPDISPLAY)、复位(RESET)、寸动(JOG)、移位(SHIFT)等功能键。 （英文版 ） Two regulations promulgated for implementation is in the party in power for a

19、sion, in December 2003 the promulgation and implementation, to strengthen the construction of the party play very important role. Along with the development of the situation, which many provisions have been unable to fully meet the comprehensive strictly administering the practice needs. One is Ji l
20、aw, more than half of the provisions and criminal law and other countries laws and regulations Repetition; two is the political discipline regulations is not prominent, not specific, for violation of the party constitution, damage the authority of Party Constitution of misconduct lack necessary and
21、serious responsibility to pursue; third is the main discipline for the leading cadres, does not cover all Party members. Based on the above situation, need to and the two is likely to be more relevant regulations first amendment. By revising, really put the authority of Party discipline, the serious
22、ness in the party tree and call up the majority of Party members and cadres of the party constitution of party compasses party consciousness. (II) two party regulations revision process the Central Committee of the Communist Party of China attaches great importance to two regulations revision . Xi J
23、inping, general books recorded in the Fifth Plenary Session of the eighth session of the Central Commission for Discipline Inspection, on the revised regulations made clear instructions. According to the central deployment, the Central Commission for Discipline Inspection from 2014 under six months

The constitution about discipline and self-discipline required specific, awaken the party constitution of party compasses party consciousness, maintaining the authority of the constitution. General Secretary Xi
32、 Jinping pointed out that no rules, no side round. Party constitution is the fundamental law, the party must follow the general rules. In early 2015 held the eighth session of the Central Commission for Discipline Inspection Fifth Plenary Session of the 16th Central Committee, Xi Jinping again point
33、ed out that constitution is the party must follow the general rules, but also the general rules. the revision of the and is Method in adhere to the regulations established for the purpose of combining rule of virtue is to adhere to the party constitution as a fundamental to follow, the constitution
34、authority set up, wake up the party constitution and party rules the sense of discipline, the party constitution about discipline and self-discipline specific requirements. 4 second is to adhere to in accordance with the regulations governing the party and the party. The Party of rule of virtue de,
