Electronic Control Options Axial Piston Pumps Series eP2/eP3 - Electronic Controls Electronic Displacement Controls EC and EF Closed loop working principle: Electronically displacement controlled eP2 / eP3 provides an output flow defined by a displacement input command and maintains its swash angle (and thereby output flow level) until a new displacement command is received. Under static displacement control conditions - i.e. as long as actual pump displacement (actual value) corresponds to displacement command (nominal value) - the control spool of the pump‘s control valve is held at...

Axial Piston Pumps Series eP2/eP3 - Electronic Controls Electronic Control Options Control Functions and Options Control Schematics As an option eP2 / eP3 can be equipped with a pressure sensor to either grant for pressure monitoring or to realize electronic pressure limitation. Pressure limitation function as well as secondary control options such as variable input torque limitation and speed compensation / flow control require the usage of a Parker supplied Pump Control Module (PCM). PCM command inputs can be both analog (0..5V) or CAN (J1939). Displacement control w/o Parker supplied PCM...
