ACCURATE GEAR DRIVEN
Extremely low backlash gear direct drive, so that repetitive positioning accuracy from a
single direction is ±15sec, lost motion by positioning from two directions for less than
2min. and the precise positioning can be determined. And Belt and Pulley are not used in
this system so it enables cost saving, unnecessary of maintenance and repair service
without adjustment of belt-tensioning
HIGH RIGIDITY
High rigidity of taper roller bearing and Ball Bearing integrated HG Series maximizes

SUPPORTING SUDDEN LOAD FLUCTUATION AND RAPID ACCELERATION
Adopting a closed loop stepping control system, Ezi-SERVO designed to maintain synchronism and does not have
step-out problem, Ezi-Actuator HG series can be driven by rapid acceleration or sudden load fluctuation because
the situation in a typical servo system that is prone to fluctuation, Hunting does not occur. For sudden load
fluctuatoin with a servo system is essential to improve the control performance does not need to gain adjustment
is gain Tuning Free Actuator.

Load variations are concerned
about the equipment without
having to adjust the gain,
HG Series enables stable
operation.
VARIETY OF CONTROLLER WITH HIGH PERFORMANCE AND MULTI-TASKING
Ezi-SERVO, high performance closed loop stepping
control system by adopting, pulse train input drives
and controller integrated drives are possible to use.

Controller Embedded Drive
(Enable to operate Multi-Axes
based on Network)
NETWORK BASED MOTION CONTROL
PC
A maximum of 16 axis can be operated from a PC
through RS-485 communications. All of the Motion
conditions are set through the network and saved in
Flash ROM as a parameter. Motion Library (DLL) is
provided for programming under Windows 2000/XP.
POSITION TABLE FUNCTION
PLC
Ezi-Actuator HG _ 4 / 5
Position Table can be used for motion control by
digital input and output signals of host controller.
You can operate the motor directly by sending the
position table number, start/stop, origin search and
other digital input values from a PLC. The PLC can
monitor The In-Position, origin search, moving/stop,
servo ready and other digital output signals from a
drive. A maximum of 256 positioning points can be
set from PLC.
SIMPLE RETURN TO HOME FUNCTION
Rotary table drive from home return often necessary
to simplify the return to home operation has been
equipped with the optional Home-sensor Set. The
sensor set comes with all the parts required for the
return to home operation, meaning you will spend
less time for designing, assembling and procuring
parts related to sensor installation.

EXTENSIVE INPUT/OUTPUT SIGNALS AND USER-DEFINED FUNCTIONS
Input 9 points / 9 points signal output according to the needs of users can be defined. Therefore, various
functions depending on the needs of the user input / output wiring must be used without changing.

⑰ Mass
The limit of mechanical strength of the reduction gear mechanism enables to make sure the applied
torque including acceleration torque and load fluctuation and it will not exceed the permissible torque.
Total sum of rotor inertia moment of the motor and the reduction gear of mechanism,
converted to a moment on the output table.
The output table speed can be tolerated by the mechanical strength of the reduction gear mechanism.
Deceleration mechanism to configure the number of teeth of two gears.
Hollow Rotary actuator can exert the maximum holding torque once the actuator is at standstill with
power supplied.
Needed number of pulse to rotate 1 revolution of output table.
A Value indicates the degree of error which is generated when positioning performs
repeatedly to the same position in the same direction.
The difference at the stopped angles achieved when the output table is positioned to the same position
during forward and reverse direction of motions. And difference is mainly caused by backlash of gear.
The difference between the theoretical rotation angle of the output table and the actual rotation angle.
And this value calculated from the input pulse number.
The permissible value of thrust load applied to the output table in the axial direction.
When a load is applied to a position away from the center of the output table, the output table receives a
tilting force and the permissible moment load refers to the permissible value of moment load
calculated by multiplying the offset distance from the center by the applied load.
The maximum value of runout of the mounted surface of the output table when the output table
rotates without load.
The maximum value of runout of the inner diameter or outer diameter of the table when the
output table rotates without load.
Actuator (plinth base) installed on the output side of the Table and value that indicates whether
the degree inclines.
IEC 60529, EN60034-5 (= IEC60034-5) classifies the dust resistance and waterproofing into grades.
A sum of Actuator configured as the output Table, deceleration mechanism, such as driving motor
plus the weight of all components.
