Digital electronics include valve’s driver + cycle generator 1 to perform the open loop motion cycle of any linear or rotative hydraulic actuator.

They are integrated to direct or pilot operated directional proportional valves and operated by digital inputs commanded by the machine electronic control unit.

2 different executions are available:

AEG drivers - 16 sets of valve’s flow regulation (axis speed) and ramp values are preset into the driver by Atos software; each set represents a phase of the whole motion cycle. The machine control unit handles, through the 4 digital inputs, the desired actuator motion cycle as a phases sequence.

AEZ controllers - as AEG but the selection of the 6 different phases, for each actuator direction, is internally made by position switches preset by Atos software. An analog position transducer has to be installed on the actuator and connected to the controller. The machine control unit commands forward and backward axis motion start.
