Back2049是正确的。 控制器应使用积分器进行补偿。 关闭电源后,应有一种方法来确保气缸不移动。 使用必须通电的截止阀。 即使阀门输入的电压为零,气缸也会趋向于伸展。
Back2049 is correct. The controller should compensate by using the integrator. When power is off there should be a way of making sure the cylinder doesn’t move. Use Blocking valves that must be energized to allow flow. Even if the valve has zero volts input, the cylinder will tend to extend. |
