PLEASE READ PRIOR TO INSTALLATION FOR SAFETY.

; AC input power must be disconnected before any wiring to the Hybrid

servo drive is made.

; Even if the power has been turned off, a charge may still remain in the

DANGER

DC-link capacitors with hazardous voltages before the POWER LED is OFF. Please do not touch the internal circuit and components. For safe maintenance, use a multimeter to measure the voltage across the +1 and – terminals. The measured value should be lower than 25Vdc for the system to operate normally.

; There are highly sensitive MOS components on the printed circuit boards.

These components are especially sensitive to static electricity. Please do not touch these components or the circuit boards before taking anti-static measures. Never reassemble internal components or wiring.

; Ground the Hybrid servo drive using the ground terminal. The grounding

method must comply with the laws of the country where the AC motor drive is to be installed.

1-3-1 Selection of Hybrid Servo Drives and Motors

Due to the differences in the hydraulic system in practical applications, the following choice of drives and motors is provided as a reference.

In the following example, a flow of 64L/min and maximum holding pressure of 175Bar are used.

Oil Pump

1. Pump Displacement per Revolution Based on the maximum flow of the system (L/min), the pump displacement per revolution (cc/rev) can be calculated. Example: If the maximum flow of the system is 64L/min and the highest rotation speed of

the motor is 2000rpm, the displacement per revolution is 64/2000*1000 = 32 cc/rev.

2. Maximum Torque of the Motor

Based on the maximum pressure (Mpa) and pump displacement per revolution (cc/rev), the maximum torque can be calculated.

Example: For the required maximum pressure of 17.5 Mpa and pump displacement per

revolution of 32cc/rev Torque = 17.5*32*1.3/(2*pi) = 116 N-m, where the factor 1.3 is used to compensate the total loss in the system.

3. Rated Torque and Rated Power of the Motor At the maximum pressure for the holding pressure, the required torque should be 1.5 times of the motor’s rated torque or less (depending on the data provided by the motor’s

1-5

manufacturer). Over such an operating condition, the over-temperature of the motor may

−

easily occur. Let u s take the factor 1.5 as an example, i f the rated to rque of the motor is 77 N-m, the motor with a power of 12kW* and a rated speed of 1500 rpm can be chosen. *The power of the motor is calculated by using

××

rpmmNTWP

)60/2()()(

4. Maximum Current of the Motor Example: Check the parameter kt (Torque/A) in the motor’s specifications, if kt = 3.37, the

maximum current is approximately 116/3.37 = 34A at the maximum torque of 116 N-m.

5. Selection of Matched Hybrid Servo Drive

Example: Look up the over-load capability for each Hybrid servo drive in the product

specification chart

If the holding pressure is at the maximum pressure of 17.5 Mpa, and a pump of 32cc/rev is used, the required motor current is approximately 34A For such a current value, the following models can be chosen VFD075VL43A-J, the overload may occur within 20 sec. VFD110VL43A-J, the overload may occur approximately after 60 sec.

NOTE

If there is no suitable motor that meets the specifications, a motor with a higher rated value can be used instead. For any information about the Hybrid servo drives or any assistance in detailed configuration of your company's products, please contact the manufacturer.

1-3-2 Selection of Pump for Hybrid Servo Motor

Select a pump with a suitable displacement based on the required flow rate and motor speed;

 If low noise is required, you can choose the screw pump or internal gear type.If a high

volumetric efficiency is required, you can choose the piston pump or dual displacement piston pump.

3. The heat sink temperature may rise to 90°C when running. The material on which the Hybrid servo

drive is mounted must be noncombustible and be able to withstand this high temperature.

4. When Hybrid servo drive is installed in a confined space (e.g. cabinet), the surrounding temperature

must be within -10 ~ 40°C with good ventilation. DO NOT install the Hybrid servo drive in a space with bad ventilation.

5. When installing multiple Hybrid servo drives in the same cabinet, they should be adjacent in a row with

enough space in-between. When installing one Hybrid servo drive below another one, use a metal separation between the Hybrid servo drives to prevent mutual heating.

; Prevent fiber particles, scraps of paper, saw dust, metal particles, etc. from adhering to the heat

sink.

Please follow the specific power supply requirements shown in Chapter 01.

There may be an inrush current during power up. Please check the chart of Appendix A-2 and select the correct fuse with rated current. Use of an NFB is optional. Please do not use a Magnetic contactor as the I/O switch of the AC motor drive, as it will reduce the operating life cycle of the AC drive. Used to improve the input power factor, to reduce harmonics and provide protection from AC line disturbances. (surges, switching spikes, short interruptions, etc.). AC line reactor should be installed when the power supply capacity is 500kVA or more and exceeds 6 times the inverter capacity, or the mains wiring distance

10m. Zero phase reactors are used to reduce radio noise especially when audio equipment is installed near the inverter. Effective for noise reduction on both the input and output sides. Attenuation quality is good for a wide range from AM band to 10MHz. Appendix A specifies the zero phase reactor. (RF220X00A) To reduce electromagnetic interference, please refer to Appendix A for more details. Used to reduce the deceleration time of the motor. Please refer to the chart in Appendix A for specific Brake Resistors. Motor surge voltage amplitude depends on motor cable length. For applications with long motor cable (>20m), it is necessary to install a reactor at the inverter output side.

Power supply input terminals for the main circuit:

Do not connect 3-phase model to one-phase power. R/L1, S/L2 and T/L3 has no

;

phase-sequence requirement, it can be used upon random selection..

It is recommend to add a magnetic contactor (MC) to the power input wiring to

;

cut off power quickly and reduce malfunction when activating the protection

function of the AC motor drive. Both ends of the MC should have an R-C surge

absorber.

Fasten the screws in the main circuit terminal to prevent sparks condition made

;

by the loose screws due to vibration.

Please use voltage and current within the specification.. Please refer to Chapter

;

1 for the specifications.

When using a general GFCI (Ground Fault Circuit Interrupter), select a current

;

sensor with sensitivity of 200mA or above and not less than 0.1-second

operation time to avoid nuisance tripping.

Please use the shield wire or tube for the power wiring and ground the two ends

;

of the shield wire or tube.

Output terminals for the main circuit:

When it needs to install the filter at the output side of terminals U/T1, V/T2, W/T3

;

on the Hybrid servo drive. Please use inductance filter. Do not use

phase-compensation capacitors or L-C (Inductance-Capacitance) or R-C

(Resistance-Capacitance), unless approved by Delta..

DO NOT connect phase-compensation capacitors or surge absorbers at the

;

output terminals of Hybrid servo drives.

The terminals of the DC reactor [＋1, ＋2], terminals at DC side [＋1, ＋2/B1]

This is the terminals used to connect the DC reactor to improve the power factor.

;

For the factory setting, it connects the short-circuit object. Please remove this

short-circuit object before connecting to the DC reactor.

DC react or

Jumper

For those models without built-in brake resistor, please connect external brake

;

unit and brake resistor (both of them are optional) to increase brake torque.

DO NOT connect [+1, -], [+2, -], [+1/DC+, -/DC-] or brake resistor directly to

;

prevent drive damage.
