Control of a double-action pneumatic drive |
摘要 |
The drive is controlled such that reduced pressure is applied during a forward motion phase and venting flow from the drive is used as dynamic control pressure to hold off application of full driving pressure until, through physical impediment, piston movement stops. This way rebounding is prevented and strong holding pressure (e.g. on welding electrodes) is made available after a low power motion phase.
