Chapter One Brief

1 BRIEF

1.1 Product Brief

The GH2000/GH3000 Series Bus AC Servo Drive Unit (It is the one

high-accuracy and high-speed full digit AC servo drive unit) is the updated

developed one based upon the GSK-Link Ethernet Bus Agreement of our company,

which provides a reliable drive control of the AC servo motor with the absolute

encoder.

1.1.1 Product Character

 It uses the GSK-Link Ethernet bus communication method; and its data transmission

rate can be performed up to about 100Mbits/s; the on-line data real-time

uploading/downloading can be carried out.

 It uses the servo motor installed with the absolute encoder, and its encoder number

can be set from17 to 28.

 One interface supports variable encoder agreed communications, for example,

TAMAGAWA, HEIDEHAIN, DANAHER, and NIKON.

 Intelligently identify the motor’s type; the SJT (A4) series servo motor type or the

default parameter call can be identified after the power is turned on.

 There are two kinds power mode selection, one is that the GH3000 series uses

AC380V; the other is that the GH2000 uses AC220V.

 Multiple power selection, the power module 30A/50A/75A/100A/150A can be

selected.

1.1.2 Use Area

It can be used in these areas, such as the mechanical manufacture, CNC machine,

printing & packing machine, spinning machine, robot and the automatic assembly line.

2 INSTALLATION

Notice

 The storage and installation of the product should be suitable for the ambient

conditions.

 The pile number of the product should be controlled, which can not be piled

them together too many, so that the product may be crushed or dropped.

 The storage and transportation of the product should be used the original

packing.

 Do not use the product with damaged or absent components.

 Do not install it on the flammable surface or near, to avoid the fire hazard.

 The servo drive unit should be installed inside the electric cabinet; prevent

the dust, corrosive gas, conductive material, liquid and the inflammable

matter from entering the machine.

 The servo drive unit and servo motor can not be shocked and im

acted.

2.2 The Installation of the Drive Unit

2.2.1 Installation Ambient

 Defense

The servo drive unit should be installed well-mounted electric cabinet, because its structure is

without defense. Prevent the corrosive gas, inflammable gas, as well as the conductive material, metal

dust, oil mist and liquid from entering the machine.

 Temperature, humidity

The ambient temperature is 0℃～+40℃, and ensure the radiating condition.

 Vibration and impact

The installation of the drive unit can not be shocked, and the vibration control should be less than

0.5G (4.9m/s

from the heavy load and impact.

) based upon the buffering measure. The installation of the drive unit must be far away

2.2.2 Installation Dimension

The GH2000/GH3000 series drive unit adopts base plate installation method, of which its installation direction is vertical to the installation surface and upward. The front is forward and the top surface is upward for cooling when the drive unit is installed. Note that the necessary space around the machine should be reserved.

In order to guarantee the ambient temperature of the drive unit does not rise consecutively, the

convection air should blow to the radiator of the drive unit inside the electric cabinet.
