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.

; This series of product s is used to c ontrol the t hree-ph ase in ductio n mot ors

and permanent magnet synchronous motors. It cannot be used for
single-phase motors or for other purposes.

; This series of products cannot be used on occasions that may endanger

personal safety.

; Please prevent children or unauthorized personnel from approaching the

Hybrid servo drive.

; Never connect the Hybrid servo drive output terminals U/T1, V/T2 and

W/T3 directly to the AC mains circuit power supply.

; DO NOT use Hi-pot test for internal components. The semi-conductor

used in Hybrid servo drive easily damage by high-voltage.

; Even if the 3-phase AC motor is stop, a charge may still remain in the

main circuit terminals of the AC motor drive with hazardous voltages.

; Only qualified persons are allowed to install, wire and maintain AC motor

drives.

; When the Hybrid servo drive uses an external terminal as its source of

operation commands, the motor may start running immediately after the
power is supplied. In this case, it may be dangerous to any on-site
personnel.

; DO NOT install the Hybrid servo drive in a place subjected to high

temperature, direct sunlight, high humidity, excessive vibration, corrosive
gases or liquids, or airborne dust or metallic particles.

; Only use Hybrid servo drives within specification. Failure to comply may result in

fire, explosion or electric shock.

;

When the motor cable between Hybrid servo drive and motor is too long,
the layer insulation of the motor may be damaged. Please add an AC
output reactor to prevent damage to the motor. Ref e r to appendix A
Reactor for details.

; The rated voltage for Hybrid servo drive must be ≤ 240V (≤ 480V for 460V

models) and the mains supply current capacity must be ≤ 5000A RMS

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

π

ω

−

=

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.

Step 7. Adjustment for injection/pressure holding

 Heat up the barrel to the required temperature and set the controller in manual control mode.
 Set the Ki values for the three stages PI to 0 (Parameters 00-21, 00-23 , and 00-25) and Kp

values to small values ( 50.0)≦

 Start the plastic injection operation. The “Targ et value” is low pressure (＜50Bar) and low flow

rate (＜30%)。

 Press the “injection" button on the operation panel for the injection operation or the machine

will enter the pressure holding operation (depending on the position of the cylinder)

 In the pressure holding state, use the software (VFD-Explorer) to observe the waveform.

Without causing the vibration of the motor, increase the speed bandwidth to the maximum
value 40Hz (Parameter 00-10).

 In the pressure holding condition, if the pointer of the pressure gauge or the monitored

pressure waveform has no fluctuation, it means that the pressure is stably fed back. It is
allowed to increase the three Kp values.

3-13

 When the pressure feedback becomes unstable, reduce the three Kp v alues by 20% (example:

the three Kp values are reduced from 100.0 to 80.0). Adjust the three Ki values to eliminate the
steady-state error so as to speed up system response.

 When the above steps are completed, increase the "target value" for the pressure command.
 Observe if the pressure feedback is stable. If there is an abnormal condition, please solve it as

follows:

Solve the pressure instability problem

Instability at high pressure

If the Hybrid servo drive has an overload condition, please increase the power rating of the
Hybrid servo drive

Instability over the entire pressure range

1. Set Parameter 00-09 = 0 to switch to the speed control

2. If the hydraulic circuit is in the closed state, send a low speed command so as to allow a

pressure feedback value of 40-50% of the value for pressure command (parameters
00-07)

3. By using the monitoring software, observe if the pressure waveform has irregular
fluctuations.

 Pressure waveform fluctuates

It may be a ground interference problem. If the motor or the three-phase power
supply is grounded, disconnect the ground wire. If the motor or three-phase power
supply has no ground wire, you can install a ground wire for anti-interference
protection.

It may be a grounding problem of the shield mesh (as the red thick line shown below).
If the shield mesh is properly grounded, the ground w ire can be removed; i f the shield
mesh has no grounding wire, install a ground wire for anti-interference protection.

Control mode VF FOCPG FOCPM

 Noises may reside in the analog input signals of the control terminals PO, PI, and QI. The noise

may affect the control stability. Use an input filter to eliminate such noise.

 If the time constant is too large, a stable control is obtained with poorer control response. If it is too

small, a fast response is obtained with unstable control. If the optimal setting is not known, adjust it

properly according to the instability or response delay.

Example: If the pressure sensor indicates 250bar at 10V. If the controller’s maximum pressure of

140bar corresponds to 10V, then Parameter 00-07=140. Set the pressure as 140bar by using

the controller, the voltage value shown on the display is about 56.0 (140/250 * 100%). Enter

this value into the Parameter 00-14. Then set the pressure as 70bar on the controller, and

now the value displayed on the keypad is about 28.0 (70/250 * 100%). Enter this value to the

Parameter 00-15. Then set the pressure as 0 bar on controller, and the voltage value shown

The Hybrid servo drive has warning messages and protection functions such as over-voltage, low-voltage,
over-current, etc. Once a fault occurs, the protection function is activated, the Hybrid servo drive stops
output, and the motor coast to stop. Please look up the cause for the fault and perform the counte rmeasure
according to the error message of the Hybrid servo drive. The error records are stored in the internal
memory of the Hybrid servo drive (last six error messages can be recorded) and can be read out through
the keypad or through the communication port.

; After a fault occurs, the RESET button will be effective only 5 seconds after the fault

condition is released.

; For Hybrid servo drives of power rating 22kW, it is necessary to wait for 5 ≦

minutes (10 minutes for 30kW) after the power is shut down to confirm that the ≧
indicator light is off and the measured DC voltage across the terminals
below DC 25V before opening the cover for inspection.
