1.1 Introduction
DA98B AC Servo Drive Uit is the second generation of fully digital AC Servo system
of our company which is employed with the new type exclusive chip DSP for motor
control, large-scale complex programmable logic device (CPLD) and IPM with big
power, which has a good integration, compact, perfect protection and highly reliability.
It is characterized with the f orientation control, interior speed control, analog speed
control etc. and is widely applied in the automation production line, packing
machinery and printing machinery and other automatic field.
Compared to stepper system,
DA98B AC Servo Driver Unit has advantages as follows:
Servomotor is equipped with encoder, its
orientation signal feedbacks to servo
driver with open loop orientation controller
to compose a semi-closed loop control
system.
The timing ratio is 1：5000，with stable
torque from low speed to high speed.
Max. speed can be 3000rpm, and the
speed fluctuation rate is less than 2％.
【Note】There is different rated speed
for different motors.
Parameters can be modified to set properly operating mode, running performance of
servo system to meet different requirements.

Chapter 2 Installation
Servo unit and servo motor should be correctly installed to avoid the mistaken operation,
to protect the machine from being broken or damaged.
2.1 Installing servo unit
Be careful for the protection against rain and sunlight while the servo unit is being
installed.
Servo unit must be installed in the electric cabinet to prevent dust, corrosive gas,
liquid, conductors and inflammable substances from entering it.
Servo unit should be fixed in the well ventilative, dampproof and dustproof
environment.
Fireproof material should be used in the installation with no permission to fix it on or
near the inflammable object.
Run the servo unit below the temperature of 45℃for reliable long term usage.
The driver is employed with bottom board or panel installation mode in the upright
direction of installation plane.

There should be convective air to the radiator of the servo unit in electric cabinet to inhibit
its environmental temperature from continuously rising.
2.2 Installing motor
Be careful for the protection against rain and sunlight.
The motor must be installed in the electric cabinet to prevent dust, corrosive gas,
liquid, conductors and inflammable substances from entering it.
The motor should be fixed in the well ventilative, dampproof and dustproof
environment.
■ The motor should be fixed in a place that is convenient for the maintenance, check
and cleaning of the motor.

■ Do not hammer the motor or its shaft to
protect the encoder from being damaged
when removing or assembling belt wheel.
Helically pressing or drawing tools should be
used for removing and assembling.
■ Servo motor cannot support heavy axial,
radial load. It should be employed with
flexible shaft coupling for load.
■ Anti-loose washer should be used to fix the motor
against loosing.
■ Oil and water should be protected from the motor for
that the oil or water from the cable which has been dipped in the oil or water can be
sticked to the motor, so such possibility should be avoided.
