Why do you need VSD?
The G7-22VSD's variable speed drive technology enables the motor
speed of the press to match your air needs. This results in energy
savings of up to 35% * compared to conventional loading / unloading
machines. In addition, G VSD's oil-cooled permanent magnet motors
can be started and stopped at full system pressure without
offloading. It also eliminates peak current shocks during start-up.
