POSITIONING DEVICE THAT PERFORMS RETRACTING ACTION USING AIR BALANCE
摘要:
When an excitation of a servo motor is released due to an emergency stop, a power outage, or another operation performed on a positioning device, the positioning device uses air supplied from an air supply source to vary pressure of an air balance, which cancels a self-weight of a vertical axis driven by the servo motor, thereby moving the vertical axis.
