(note1)Operating pressure may be limited by maximum RPM depending on the motor output

(note2)This is the theoretical flow under no load. The actual flow will vary depending on the load pressure.

(note3)Rated pressure is (available) pressure at the rated torque of the motor, and maximum operating pressure is pressure output at 150% torque. However, if this pressure exceeds 30MPa, the maximum operating pressure of the hydraulic unit is limited to below 30MPa.

(note4)An auxiliary tank can be connected if fluctuation in oil volume is greater than allowed values. Contact us for information.

(note5)An oil tank will be separately necessary. Our company can make the oil tanks so contact us for information if you need one.

(note6)Operating conditions may limit the maximum RPM and operating pressure to values lower than those shown in the table above, contact us for more information.
Contact us about operations in which pressure is continuously added over a long period of time because the temperature of the hydraulic fluid sometimes rises due to the operating pressure, so restrictions on the operating pressure and the additional installation of a refrigeration system may be necessary.

(note7)The operating hydraulic fluid temperature is affected by a variety of factors such as the hydraulic unit installation environment, operational method, load condition, etc. so be sure to confirm with your customer in a situation in which the production machine is operating.
In the case that the hydraulic fluid temperature exceeds the operational hydraulic fluid temperature range, it will be necessary to additionally install a separate refrigeration system, so contact us for information.

• The connector for controller and the pins are attached.
• If you use a spacer for the servo controller (option: FZV-8676-02A-01), the installation dimensions will be the same as for the former design [EPD-PD2-10(-A)-D2-10], and the height of the connector from the installation surface will be almost the same.

Servo amplifier specification

(note1) Operating power source :THREE-PHASE AC200220V 50/60Hz
(note2) Separate motor cable and encoder cable are needed to connect the servo motor installed on the hydraulic unit.
(note3) An external regenerative resistor may need to be added in some operating conditions if the capacity of the built-in or external regenerative resistor is not sufficient. For more details contact us with information about your operating conditions (attach the load motion diagram).
(note4) Cable connector included.

Application examples and effects

Bending machine	More compact machines and improved precision of processing dimensions
Caulking machine, Press machine	These units are able to control swaging (pressured insertion) capability and control the swaging (pressured insertion) completion position so quality management is easy. A positioning mechanism using a conventional mechanical stopper is unnecessary, liberating you from variations in results due to workers.
Grinding machine	Improves the precision of the positioning of the grinding commencement position, having a large energy-saving effect when continuously pressurizing over a long period of time using a fixed pressure.
Precision Press	Improves product quality by smoothly switching from high-speed movement to pressurization control without any surge. Cycle time is shortened.
Straightening machine	It achieves energy-saving, low noise, and a reduction in the amount of hydraulic fluid. Space is saved and transportation and packaging costs are reduced by installing a hydraulic unit in the machine.
Other	A full range of hydraulic systems for machines which are required to be more compact, machines which require a high thrust that cannot be obtained with ball screws, etc.
