  • Page 4: Features

    Features The digital amplifier and controller card ER9.4-10 is used for displacement control SP of EATON variable piston pumps in X and W design. The swash plate is positioned by a Vickers Proportional Valve KDG4V-3. The digital amplifier and controller card meet the industrial standard for EMC EMV 89/336/EEC, which ensures a high interference security and low interference emission.

  • Page 5: Function

    Fig. 1 shows an EATON swash plate pump in W design with proportional valve adjustment displacement control SP. The ER9.4-10 card measures the actual position of the swash plate using a swash plate sensor, compares the swash plate angle with the set value, and drives the servo valve D631.

    Pin Assignment on Back Connector X1 Table 2 shows the pin assignment on the 48 pin connector of card holder HC000000315303. Values in brackets {} have no function in proportional valve adjustment displacement control mode (SP). The wiring scheme, necessary for SP-Control is shown in Fig. 7. Additional wiring, e.g. to use monitoring function, can be done optional by customer.

    ER9.3-10 Fig. 2: Display and keypad Fig. 2 shows the front face of the ER9.4-10 card. The function of these elements is described in Table 3. The sockets “A/B” and “C/D” can be used to measure the solenoid currents independently.

  • Page 10: Setting Of Parameters

    Setting of Parameters The digital controller and amplifier ER9.4-10 has a display and keypad to change the card parameters. Additionally, it is possible to change the card parameters using the enclosed ER9.4-Tool with a PC via the RS232 serial interface on the front.

    Fig. 3: Block diagram of Input Signals Digital Set Values Digital set points are programmable, and are activated by digital inputs. Four (optionally five) of these programmable set points can be selected with the respective input and an associated direction “+“ or “-“.

  • Page 14: Ramp Function

    Ramp Function Digital set points are integrated according to the ramp function generator. For each change in direction the ramp time can be independently set from 0 to 39.5 sec (0.01 sec resolution). The ramp characteristics are as follows: r1.01 0 to negative values r1.02 negative values to 0...

    Commissioning Non Warranty This operating manual represents the knowledge of Eaton and during the drafting of this manual, the greatest possible care was taken. Nevertheless, Eaton disclaims any responsibility and liability claims for individual applications of the user. This is particularly true in cases of non-compliance, omissions, faults, misinterpretations and misunderstandings.

    The solenoids are connected at terminal 22bdz (port A), terminal 28bdz (port B), terminal 24bdz (port D) and 30bdz (port C). The terminals bdz are bridged on the amplifier. We recommend using all three terminals. Terminal 18d is the digital output of GND. This terminal is used as a point of reference for the serial interface.
