| 给定频率的设置 Setting of a given frequency 给定频率是指给变频器设定运行的频率，给定频率可以由操作面板给定，也可以由外部方式给定，其中外部方式又分为电压给定和电流给定。 The given frequency refers to the frequency set to the converter. The given frequency can be given either by the operation panel or by the external mode, in which the external mode is divided into voltage setting and current setting. 一、操作面板给定频率 I. Given Frequency of Operating Panel 操作面板给定频率是指操作变频器面板上有关按键来设置给定频率，具体操作过程如下 The given frequency of the operation panel refers to the operation of the keys on the frequency converter panel to set the given frequency. The specific operation process is as follows. a．用“设置”键切换到频率设置模式。 A. use the "set" key to switch to the frequency setting mode. b．用“▲ ”和“▼”键设置给定频率值 B. Set the given frequency value with the and keys c．用“确认”键存储给定频率。 C. Store the given frequency with the confirmation key. 二、电压给定频率 2. Voltage Given Frequency 电压给定频率是指给变频器有关端子输入电压来设置给定频率，输入电压越高，设置的给定频率越高，电压给定可分为电位器给定、直接电压给定和辅助给定。 Voltage given frequency refers to setting a given frequency to the input voltage of the transducer terminal. The higher the input voltage is, the higher the given frequency is. Voltage given can be divided into potentiometer given, direct voltage given and auxiliary given. 1、电位器给定方式 1. Potentiometer setting mode 给变频器+10V、AVI、ACM端子按下图示方法接一个1／2W，1kQ的电位器，通电后变频器AVI脚会输出10V电压，调节电位器会使AVI脚电压0～10V范围内变化，给定频率就在0～50Hz之间变化。 Connect the converter + 10V, AVI and ACM terminals with a potentiometer of 1/2W and 1kQ by the following graphic method. After power-on, the converter AVI foot will output 10V voltage. Regulating the potentiometer will change the AVI foot voltage in the range of 0-10V, and the given frequency will change between 0-50Hz. 2、直接电压给定方式 2. Direct Voltage Setting 该方式是在AVI、ACM端子之间直接输入0～10v电压，给定频率就在0～50Hz之间变化。 This method is to input 0-10V voltage directly between AVI and ACM terminals, and the given frequency varies between 0-50Hz. 三、电流给定频率电流给定频率是指给变频器有关端子输入电流来设置给定频率，输入电流越大，设置的给定频率越高。电流给定频率方式如下图所示。要选择电流给定率方式，需要将电流选择端子AU与SD端接通，然后给変频器端子4输入4～20mA的电流，给定频率就在0～50H之间变化。 3. The given frequency of current and given frequency of current refers to setting the given frequency by giving the input current of the relevant terminals of the converter. The larger the input current, the higher the given frequency. The frequency of the current given is shown in the following figure. In order to select the current setting rate mode, the current selecting terminal AU and SD should be connected, and then the current of 4-20 mA should be input to the terminal 4 of the frequency generator. The given frequency varies from 0 to 50 H. |
