Delta HES Series Instructions For Use Manual page 3

Thank you for choosing the Hybrid Energy System (HES) designed exclusively for the Delta Injection Machine,
which consists of Hybrid Servo Controller (VFD-VJ) series and servo oil pump.
These production instructions provide the users with complete information regarding the installation, parameter
configuration, anomaly diagnosis, troubleshooting, and routine maintenance of the Hybrid Servo Driver. To ensure
correct installation and operation of the hybrid servo driver, please read the instructions carefully before installing
the machine. In addition, please store the enclosed CD-ROM properly and pass down to the machine users.
The Hybrid servo driver is a delicate power electronics product. For the safety of the operators and the security of
the machine, please only allow professional electrical engineers to conduct installation, tests, and adjust machine
parameters. Please carefully read the contents of the instructions that are marked with "Danger" and "caution".
Please contact your local Delta agents for any questions and our professional team will be happy to assist you.
PLEASE READ PRIOR TO INSTALLATION FOR SAFETY.

Make sure to turn off the power before starting wiring.

Once the AC power is turned off, when the POWER indicator of the Hybrid Servo Controller
is still on, it means there is still high voltage inside the Hybrid Servo Controller, which is very
dangerous and do not touch the internal circuits and components. To conduct the
maintenance safely, please make sure the voltage between ＋1 and － is lower than
25Vdc using the handheld multimeter before starting the operation.

The internal circuit board of Hybrid Servo Controller houses CMOS IC, which is vulnerable
to electrostatics. Please do not touch the circuit board by and without any anti-electrostatics
measures.

Never modify the components or wiring inside the Hybrid Servo Controller.

The E
uses the third type of ground scheme while the 460V series uses special ground.

This series of products cannot be operated in environments that endanger human safety.

Please keep children or strangers from approaching Hybrid Servo Controller.

Never connect AC power to the output terminals U/T1, V/T2, and W/T3 of Hybrid Servo
Controller.

Please do not conduct stress test on the internal components of Hybrid Servo Controller, for
the semiconductor devices therein may be damaged by high-voltage breakdown.

Even when the servo oil pump is off, the main loop terminal of Hybrid Servo Controller can
still be loaded with high voltage that can be seriously dangerous.

Only qualified professional electrical engineers can conduct tasks of installation, wiring, and
maintenance of Hybrid Servo Controller。
terminal of Hybrid Servo Controller must be grounded correctly. The 230V series
