III

Connection

● Only qualified persons can do or check the connection.

● Connection and checking cannot be performed in 5 minutes after the power supply is

switched off.

● The servo driver and servomotor must be grounded.

● Explosion or operation incident caused by mistakenn voltage or polarity of power supply

may occur.

● Connection is permitted after stable installation of servo driver and servomotor.

● Insulate and Protect from squeezing wires to avoid electric shock.

● Correctness and fastness of connection must be assured, otherwise the motor will run in a

mistakenn direction and the equipment may be damaged by loosen connection.

● U, V, W terminals must not be connected reversely and connected with AC power supply.

● Servomotor must be directly connected with servo driver without connecting of

capacitance, inductance or filter.

● Protect conductive fastener and end of wire from entering servo driver.

● Wires and non-thermal protective objects are not permitted to approach to servo driver

radiator and servomotor.

● Freewheeling diode in parallel on output signal of DC relay must not be connected

reversely.

Debugging

● Stable assembly and fixation of servo driver and servomotor, correctness of power voltage

and cable connection must be assured before the power supply is switched on.

● Servomotor should run in dry run mode while debugging. Load debugging should be

performed after the parameters are rightly set to avoid damage of machine and equipment

caused by maloperation.

Usage

● Emergency circuit should be connected to make the machine stop running immediately

with power cut off when an incident occurs.

● The running signal must be off before resetting an alarm or it will restart suddently.

● The servo driver must be matched with the specified servomotor.

● Do not frequently switch on/off the power supply of servomotor to avoid damaging

servomotor.

● Do not touch the driver radiator and the servomotor in running and power off to avoid

Warning

scalding .

● Must not refit the servo system.

Troubleshooting

● Do not touch the terminals in 5minutes after power is off because of the high voltage of

servo driver.

● Only qualified persons can dismount or maintain it.

● Resolve malfunction after alarming, and reset alarming signal before restarting.

● Keep away from machine while power is on after instantaneous power off because machine

might start suddently.(No danger occurrence in restarting should be assured in design. )

Option

● Rated torque of servomotor should be higher than that of effective continuous load.

● Inertia ratio between the load and the servomotor should be less than that of

recommendation.

● The servo driver should be matched with the servomotor.

Overview

1.1 Introduction

AC servo technology has been advanced and improved since the early of 90th last century and

applied to NC machine, printing packing machinery, textile machinery, automatic production line

and other automatic fields.

With high integration, compact, excellent reliability, DA98A AC servo system is the first full digital

one in China, employed with the advanced digital signal processor DSP(TMS320f2407A) from

America TI company, large-scale complex programmable logic device and MITSUBISHI intellegent

power module, and with PID operation to execute PWM control. Its performance has reached the

same overseas level.

DA98A AC servo system has advantages

compared to stepper system as follows:

zAvoiding out-of-step

Servomotor is employed with encode, its

position signal feedbacks to servo driver with

open loop position controller to compose a

semi closed loop control system.

zSpeed ratio, constant torque

The timing ratio is 1：5000，with stable torque

from low speed to high speed.

zHigh speed, high precision

Max. speed can be 3000rpm, position

precision of turning is 1/10000r.

Note: There is different max. speed for different

types.

zSimple and flexible control

Parameters can be modified to set properly operating mode, running performance of servo system

to meet different requirements.
