Fana06b-6120-H075 servo drivers A06B-6114-H106, A06B-6079-H208, A06B-0590-B004#7008, A06B-6077-H106 control the power for electro-hydraulic rotation angle and pressure control and A4VS…HS4 and A2V…EO4 axial piston units. The control system consists of the following modules: axial piston device, including proportional valve 4WRE6V…-2X/ /822 (A4VS…HS4) or 4WRE10V…-2X (A2V…EO4) with sensor, which is used to detect the rotation angle and valve position (see open loop RE 92050 for technical data, Open loop RE 92100 closed loop and RE 92076) Recommended pressure transmitter HM17, VT-VPCD amplifier card for detecting system pressure, which is used to realize all required electrical functions HS4 or EO4 control. The scope of the following documents is A4VS…HS4, but it also corresponds to A2V…EO4.
