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.
