Preface
Thank you for choosing Delta’s high-performance hybrid servo drive VFD-VJ Series dedicated to
plastic injection molding machine. The VFD-VJ series products are made of high quality
components and materials that incorporate the latest microcontroller technology.
This manual is to be used for the installation, parameter setting, troubleshooting, and daily
maintenance of the hybrid servo drive. To guarantee safe operation of the equipment, read the
following safety guidelines before connecting power to the hybrid servo drive. Keep this operating
manual at hand and distribute to all users for reference.
To ensure the safety of operators and equipment, only qualified personnel familiar with hybrid servo
drive are to do installation, start-up and maintenance. Always read this manual thoroughly before
using VFD-VJ series Hybrid Servo Drive, especially the WARNING, DANGER and CAUTION notes.
Failure to comply may result in personal injury and equipment damage. If you have any questions,
please contact your dealer.
Firmware version: V1.01
PLEASE READ PRIOR TO INSTALLATION FOR SAFETY.
DANGER
 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 remain in the DC-link
capacitors with hazardous voltages before the POWER LED is OFF. 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. 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 region where the AC motor drive is to be
installed.
 This series of products is used to control the three-phase induction motors 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 output terminals U/T1, V/T2 and W/T3 of the hybrid servo
drive directly to the AC mains circuit power supply.
 After finishing the wiring of the AC motor drive, check if U/T1, V/T2, and W/T3
are short-circuited to ground with a multimeter. Do NOT power the drive if short
circuits occur. Eliminate the short circuits before the drive is powered.

 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 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. Refer 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 (10000A
RMS for the  40hp (30kW) models).
 Pay attention to the following when transporting and installing this package
(including wooden crate, wood stave and carton box):
1. If you need to sterilize, deworm the wooden crate or carton box, do not
use steamed smoke sterilization or you will damage the product inside.
2. Use other ways to sterilize or deworm.
3. You may use high temperatures to sterilize or deworm. Leave the packaging
materials in an environment of over 56°C for 30 minutes.
4. It is strictly forbidden to use steamed smoking sterilization. The warranty does
not cover the product damaged by steamed smoking sterilization

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.
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 would be 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: If the required maximum pressure is 17.5 Mpa and pump displacement per
revolution is 32cc/rev, the maximum torque would be 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.

VFD-VJ Air Cooled I 1. Description of Hybrid Servo Drives
1-7
3. Rated Torque and Rated Power of the Motor
When holding pressure is under maximum pressure, the required torque cannot exceed
1.5 times of the motor’s rated torque (depending on the data provided by the motor’s
manufacturer) at most or the motor would be overheated. Let us take the factor 1.5 as an
example, if the rated torque 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 )60/2()()(






rpmmNTWP
4. Maximum Current of the Motor
Example: Check the parameter kt (Torque/A) in the motor’s specifications fist. 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 heavy-duty capability for each hybrid servo drive in the product
specifications.
If the holding pressure is under the maximum pressure of 17.5 Mpa by using
with a pump of 32cc/rev, the required motor current would be approximately
34A.
Under such a current value, overload may occur in different times due to
different models.
For model VFD450VL43A-J, the overload may occur within 20 sec..
For model VFD550VL43A-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 power 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.
 Use wall-mounting method and follow the space requirements during the installation of the hybrid servo
system.

1) Mount the hybrid servo drive vertically on a solid surface object by screws. Other directions are not
allowed.
2) Because the hybrid servo drive generates heat during operation, there should be enough space for
cooling airflow as shown in the figure above. Leave enough room for heat dissipation when installing.
Do not install the drive beneath equipment that is not heat-resistant because the generated heat move
upwards. If the drive can only be installed in a cabinet, its ambient temperature should be within
regulated values. Installing the drive in a confined and insufficient cooling space would make it
malfunctioned.
3) The temperature of heat sink in the drive varies with environmental temperature and its load capacity
during its operation, reaching nearly the highest temperature of 90°C. Therefore, the material of the
drive's backside should be able to bear such a high temperature.
4) If more than one drive are installed in one cabinet, it is recommended to install them horizontally and
side by side to reduce heat generated from each other. If they can only be installed up and down, spacer
plates should be put between them to decrease heat generated from lower side to upper side.
5) For information about air conditioning layout, please refer to the heat dissipation of hybrid servo drive (W)
table below.
NOTE
Prevent substances like fiber particles, scraps of paper, sawdust, metal particles, and so on from
entering the hybrid servo drive. The hybrid servo drive should be installed in the cabinet made from
non-combustible material such as metal to prevent from fire accident.
