Description of IH Servo Drive Pack
The IH servo drive pack drives the pump with an AC servo motor, and the pump supplies pressured oil bidirectionally.
This results in a simple hydraulic control system where the load cylinder is simply connected to both outlet ports without control valves. The pump draws oil by using the self priming valve to compensate oil in
The deviation of the control signals and sensor signals from the host is sent to the servo driver to drive the AC servo motor, consequently forming a feedback loop. The sensor signals come from the position sensor on the cylinder and the pressure sensor on the servo drive pack.
