作为速度控制的上位机,都是通过交流伺服驱动器的控制端子来控制的,如三洋的伺服驱动器是通过CN1的第20,2脚输入不同的电压来控制伺服马达的达转速,也就是说不同的电压是对应着不同的转速.
As a speed control of the PC, are controlled by the control terminal of the AC servo driver, such as Sanyo servo drive is through the cN1 pin, 20,2. Different input voltage to control the servo motor of speed. That is to say different voltage corresponding with different speed.
当飞车时,这时输入到P20.21的电压一定很高,使电机飞快的转动.而这个控制的电压又是那里来得呢,是通过在上位器中的伺服驱动板上的一个DA芯片转换来的,DA芯片是一个双极性供电IC,当提供给这个双极性DA供电的电源存在问题时,当然就会产生飞车。如双极性电源少一路时,这时控制的输出电压就会不平衡,这时就会飞车了。
When the speed, then input to must have a high P20.21 voltage and the motor fast rotation. The control voltage is there come, it is driven by servo in the upper plate of a DA conversion chip and Da chip is a bipolar power supply IC, when provided to the bipolar Da power supply power supply problems, of course, will have a runaway. If the bipolar power supply less, when the control of the output voltage will be unbalanced, then it will speed up the.
处理方法:
Treatment method:
查寻DA芯片的供电,如果这个双极性电压是开关电源供电的,确定开关电源的输入电压是过低还是过高,电源的地线是否都是接地良好,开关电源各组输出的电压是否正常,再确定双极性电压和双极性电压的地到上位器的连接线是否可靠接触是否良好。
Search for the Da chip power supply, if the bipolar voltage switching power supply to determine the power switch of the input voltage is too low or too high, the earth wire of the power supply are well grounded, switch power supply each output voltage is normal, and then determine the bipolar voltage and bipolar voltage to the host device connecting line is reliable contact is good.
在日常使用中要想保证电脑弹簧机正常运转,首先必须解决好电源问题。电源问题是取决于电脑弹簧机能否开起来的重要的保证。
In daily use in order to ensure the normal operation of the computer spring machine, we must first solve the problem of power supply. The power supply problem depends on whether the computer spring machine can open up the important guarantee.
