[1. Introduction]
Thank you for selecting IPM Motor Drive Hydraulic Unit <Super Unit>.
Using the oil hydraulic technology and energy-saving IPM motor drive system that DAIKIN originally developed, the IPM Motor Drive Hydraulic Unit <Super Unit> provides overwhelmingly excellent energy conservation performance and advanced functions.
Before using the SUT Series <Super Unit>, please read this manual thoroughly, and handle and maintain this unit properly, so that this unit can retain excellent performance for a long period.
The components of this unit may be modified for the purpose of quality/performance improvement or other reasons. In such a case, some parts of this product may be different from those described in this manual.
[2. Features and Structure]
(1) Energy conservation
Since the motor unit uses the highly efficient IPM motor drive system that DAIKIN originally developed, the Super Unit provides extremely high energy efficiency.
The Super Unit uses the autonomously-switching dual pump system that enables autonomous control of combination mode/single mode switching according to load pressure by using the dual fixed-capacity pumps (small-capacity and large-capacity pumps) and the switching valve.
When a large flow rate is required, the dual fixed-capacity pumps (small-capacity and high-capacity pumps) are operated together at a high rpm. When a large flow rate is not required (during a pressure holding period), only the small-capacity pump is operated at a low rpm. Thus, the Super Unit can remarkably reduce energy consumption.

(2) Multi-stage speed control/Multi-stage pressure control, and shockless control functions
The Super Unit enables multi-stage pressure control/flow rate control by selecting 16 patterns of P-Q characteristics that have been registered in the controller from the master machine (via a contact input).
The Super Unit enables shockless control by setting or adjusting the rising/falling time during changeover of P-Q characteristics.
Since the conventional valve-controlled functions are controlled with the pumps, the Super Unit can simplify the system configuration and reduce the cost for switching between high-speed and low-speed operations and multi-stage pressure control of presses.

PIM-00004△1 [Operation Manual] 9/61
[5. Precautions for Use]
(1) To provide excellent energy-saving performance, this hydraulic unit provides the solenoid valve that switches the dual pump operation between the combination mode and the single mode. If the machine operating point is close to the solenoid valve switching point, the pump operation may become unstable. In this case, it is necessary to adjust the flow rate setting (qH) or the pressure setting (PL) to a value below the solenoid valve switching point.
Furthermore, adjusting the dead zone provided around this switching point (see page 37 on p29,p30.) allows you to stabilize operation.
(2) In this hydraulic unit, the motor pump unit is equipped with vibration suppressing rubber to prevent vibration of the motor pump unit from being conveyed to the whole unit. For this purpose, the discharge pipe provides a large degree of freedom. Therefore, when connecting the discharge pipe, be careful that the discharge pipe will not touch the cover even if the pipe shakes with reaction force of the hose.
The piping to the unit should be connected with a hose, so that vibration of the motor pump unit will not be conveyed to the machine.
(3) This hydraulic unit is equipped with an AC fan for cooling of hydraulic oil and motor.
To ensure spaces for air intake and exhaust, do not place an obstacle at 10 cm or shorter distance from the fan motor air intake and exhaust planes.
(4) Frequently turning ON/OFF the power supply causes the controller service life to be remarkably shortened.
If you start and stop the hydraulic unit repeatedly by turning ON/OFF the power supply at intervals of 8 minutes or less, use the “start/stop” function using the start/stop signal. (See page 24)
When the hydraulic unit is started/stopped with the start/stop signal, the time interval to restart the unit after stop command input should be at least 0.5 sec.
(5) This hydraulic unit incorporates a check valve that provides an orifice in the discharge line. If high response is required for machine pressure release or other purpose, the machine must be provided with an additional pressure release circuit.
If the load volume is large, you may hear a fluid flow sound from this orifice when the unit is stopped.
However, this phenomenon does not indicate abnormality.
(6)
This hydraulic unit uses an IPM motor, which generates counter-electromotive force during changeover
(regenerative operation). If the motor is frequently turned ON/OFF in the operating condition that easily generate counter-electromotive force (a large load volume causes a large load reaction force accordingly), it causes regenerative overload, resulting in unit stop.
(7) This hydraulic unit is equipped with a safety valve.
This safety valve has been set to a specified pressure before shipment. However, the set pressure of the safety valve may decrease while the machine is repeatedly used for a long period, or due to contaminants in the hydraulic oil.
If this unit is continuously used with the safety valve activated, it may output an alarm due to a temperature rise and so on.
In this case, re-adjust the high pressure safety valve pressure setting according to “Attachment:
High-pressure Safety Valve Adjustment Procedure”
(8) Continuous operations with maximum pressure is only allowable when operating flow rate is14.0L/min.

[10. Test Run]
Supply hydraulic oil into the tank to the specified level, and conduct a test run after piping and electric wiring are completed.
(Before turning ON the power supply, re-check if the ground cable and power supply cable are securely connected.)
Start check
Turn ON the switch on the machine control panel.
[1] Check the pump operation sound, and confirm that a pressure indicated on the display panel increases.
[2] Confirm that the oil cooler AC fan motor is running.
Flushing
NOTE) This hydraulic unit takes a warm-up time of approx. three seconds until it starts operation after power-ON.
(The pressure rising time varies depending on the pipe volume.)
Furthermore, the hydraulic unit takes a time to increase the circuit pressure above the set pressure of the pressure switch. During this period, the pressure switch signal may be output depending on the pipe condition (pipe volume). In such a case, set up the master machine so that it dose not receive the alarm output.
After completion of the start check, loop all pipes (except for the actuator), and execute flushing operation for approx. two hours while running hydraulic oil through the filter.
Oil replacement
Air vent
To conduct flushing operation, loop all pipes, and run the oil through a filter.
Before flushing operation, check all pipe connections for looseness and oil leak.
After completion of the flushing operation, check the return filter indicator.
If the filter is clogged, replace the filter element, and drain all hydraulic oil from the tank through the oil drain port of the tank.
Fill new hydraulic oil through the oil filling port (air breather) to the specified level.
(Use new clean hydraulic oil with pollution degree of NAS Class 9 or lower level.)
Evacuate air from the hydraulic circuit completely. If air is not completely evacuated, the following phenomena may occur.
[1] Abnormal operation of cylinder actuator
[2] Abnormal sound of pump and valve
NOTE: Specifications of the return filter element are subjected to change.
When replacing the element, check the type of the return filter incorporated in the unit, and order the specified type of element.
DANGER
When evacuating air, high-pressure and high-temperature oil may spout out. Pay attention to oil splash.

PIM-00004△1 [Operation Manual] 33/61 b) Setting mode
The setting mode allows you to set or change a parameter such as pressure and flow rate on the operation panel.
For the parameters that can be specified or changed in the setting mode and their adjusting ranges, see the list of setting ranges on p. 36.
For the initial values and adjusting ranges of non-standard models or custom-made models, see the delivery specifications on separate sheets.
NOTE:
[1] The above flow rate set value is a theoretical value (the product of theoretical displacement volume by rpm). It is slightly different from the actual flow rate.
[2] For the pressure/flow rate setting parameters ([P13] through [P28]), the following settings are not allowed. a) If [PH.*] is set lower than [PL.*], [PL.*] automatically becomes equal to [PH.*]. b) [PL.*] cannot be set higher than [PH.*]. c) If [qL.*] is set lower than [qH.*], [qH.*] automatically becomes equal to [qL.*]. d) [qH.*] cannot be set higher than [qL.*].
Wherein, [PH.*] is a high-pressure pump pressure setting, and [qH.*] is a small flow rate setting.
[PL.*] is a low-pressure pump pressure setting, and [qL.*] is a large flow rate setting.
Example) If the [PH.0] setting is changed to "5.5 MPa" when [PL.0] is set at "6.0 MPa", the [PL.0] setting is automatically changed to "5.5 MPa".

* [P08] 2: Expansion of pressure switch function
Expansion of pressure switch function is enabled when the [P18] (alarm output combination setting) parameter in the setting mode is set to “2”.
Normally, the [P01] (pressure switch setting) parameter specifies the pressure that activates the pressure switch.
In this case, the pressure that activates the pressure switch is constant, regardless of the current P-Q selection.
On the other hand, the “expansion of pressure switch function” parameter specifies a ratio to the pressure setting for each P-Q selection. Therefore, the pressure that activates the pressure switch varies depending on the pressure setting for the P-Q selection. The setting range is 0 to 150 [%].
If “expansion of pressure switch function” is enabled, the alarm output is set to “individual alarm output”.
P08 = 0 (Individual alarm output), or

[Attachment: High-pressure Safety Valve Adjustment Procedure]
With this hydraulic unit, it is not necessary to change the high-pressure safety valve settings in detail, even in the case of pressure setting adjustment. This hydraulic unit uses the IPM motor, resulting in drastic improvement of the motor drive system. Thus, it ensures stable performance without necessity of high-pressure safety valve setting adjustment.
In any of the following three cases, adjust the safety valve with reference to "Safety Valve Adjusting
Procedure".
1. When safety valve setting adjustment is required:
Even if the hydraulic unit is used with the maximum pressure setting, the safety valve will not be activated under normal pressure control (except for the transient period when the circuit is blocked due to stop of the master machine hydraulic actuator). However, the safety valve set pressure will be lowered due to long-term repeated operations and contaminants in the hydraulic oil. If the safety valve is activated even with normal conditions, safety valve adjustment is required.
[Judgment criteria]
The hydraulic oil temperature rising time is shorter than before.
When the safety valve adjusting screw is turned in the tightening direction, the rpm indication in the pressure hold status is lowered.
2. To minimize surge pressure that much exceeds a set pressure, safety valve adjustment is required in consideration of the withstand pressure of the hoses being used.
3. When the pressure set value is changed from the factory setting:
In order to suppress surge pressure to protect the master machine peripheral equipment (actuator, pressure gauge, etc.), it is recommended that the safety valve set pressure should be set "pressure of the unit + 1.0
MPa".
DAIKIN INDUSTRIES, LTD.

<High-pressure Safety Valve Adjustment Procedure>
[1] Referring to the enlarged view of the high-pressure safety valve shown below, loosen the lock nut. (M10 lock nut, Width across flats: 14 mm)
[2] According to the pressure adjusting screw length reference chart, determine the screw length corresponding to a desired control pressure setting.
* Tip of adjusting screw: Hexagon socket head, Width across flats: 5 mm
* One turn of the adjusting screw changes the pressure by approx. 7.7 MPa.

[7] Tighten the lock nut. This completes the safety valve adjusting procedure.
(When tightening the lock nut, be careful not to allow the adjusting screw to turn.)
DAIKIN INDUSTRIES, LTD.
PIM-00004△1 [Operation Manual] 54/61
CAUTION: To set the safety valve to 20 MPa or higher pressure, caution is required.
(Excessively increasing the safety valve setting causes the pump to be damaged by surge pressure.)
To adjust the safety valve, follow the procedure below:
First, set the safety valve by following the above steps [1] to [5] so that the pressure setting is
7.7 MPa (corresponding to one turn of the pressure adjusting screw) lower than a target pressure.
Then, tighten the adjusting screw by turning it clockwise by one turn, and conduct the above step [7].

The above chart shows the case where “P03” (Pressure switch display hold setting) is [1] or [2].
When “P03” is [0], an actual pressure value is displayed.
When the stop command is activated by the start/stop signal, the pressure switch is in the normal condition.
The “P01” and “P02” settings (above [1] and [2]) can be changed in the setting mode.
For the setting procedure and setting range, see “Operating procedure for each mode: b) Setting mode” on p. 39.
Note) For the purpose of explanation, the above “1-7 Alarm classification [4]” chart shows the case where the pressure switch is activated without a dead zone. Actually, however, the pressure switch has a dead zone of approx. 0.5 MPa.
Note) Set the time interval after a stop signal at 0.5 seconds or longer.
