Chapter One Overview

1.1 Product Introduction

The AC servo technology has undergone a rapid development since the beginning of 1990s, during which period this technology has been increasingly mature and its performance has been constantly improved. Now this technology has been widely applied to such automatic fields as CNC machine tools, printing and packing machines, textile machinery and automatic production lines.

DA98D AC servo drive unit (all called full digital AC servo drive device) is a new generation of full digital AC servo drive unit produced by our company. This product includes two control modes of speed and position. It can be matched with various open-loop and closed-loop control systems and has been widely applied to CNC machine tools and

automatization industry. Internationally advanced special-purpose chip for motor control (TMS320LF2407A DSP), complex programmable logic display (CPLD) and MITSUBISHI intelligent power

module (IPM) are adopted inside the servo, so it has

such advantages as high degree of integration, controller compact, perfect protection and good reliability. The

optimal PID is employed to achieve PWM control. Performance of this product has reached internationally advanced level among its peers at home

and aboard.

Compared with stepper drive, DA98D AC servo unit has the following strong points:

zAvoid out-of-Synchronization Phenomena

Servo motor has encoder on itself and the position signal will be fed back to the servo drive unit, forming a semi-closed loop system together with the open-loop position controller.

zWide speed ratio and constant torque

Speed ration is 1:5000, with stable torque characteristics from low speed to high speed.

zHigh speed and precision

The maximal rotation rate of servo motor can reach 3000r/min, with a rotary positioning

precision 1/10000r.

Notes: maximal rotatation rate is not the same with different models of servo motor.

zEasy and flexible control

Through parameter changing, working methods and characteristics of the servo drive unit can be properly set to comply with different requirements.

DA98D User Manual

The servo driver does not have any protection within its own structure, so it must be installed within the electric cabinet with good protection and prevented from contact of corrosive and combustible air. Conductive matters, metal dust, oil fog or liquid shall be prevented from entering inside.

2 Temperature and Humidity

The environmental temperature shall be kept between 0 and 50 , while temperature for long-term safety operation shall be kept below 45 . Good conditions for heat radiating shall be guaranteed.

3 Vibration and Impact

When installing the drive unit, vibration shall be avoided. Vibration reduction measures shall be taken to control the vibration below 0.5G (4.9m/S2).

2 Installment Methods

(1) Ways of Installment

The user can adopt the ways of installment by back panel or panel. The installment shall form an upward right angle with the installment plane. Fig. 2.1 is a schematic diagram for installment by back panel and Fig. 2.2 is a schematic diagram for installment by panel.

DA98D User Manual

2.3 Installment of Servo Motor

Attention

zShock on the motor shaft or encoder shall be forbidden to prevent the motor from vibration or impact.

zThe motor shall not be moved by drawing motor shaft, leading-out wire or encoder.

zLoad on the motor shaft shall not surpass its limit; otherwise, the motor may be damaged.

zThe motor must be firmly installed with anti-loosening measures.

1) Installment Environment

1 Protection

Currently, GSK SJT series and Huazhong Series of servo motor are not water resistant, so liquid must not be spattered on the motor during installment. Oil or water must be prevented from entering inside the motor through leading-out wire or the motor shaft.

Notes: if the user needs water-resistant servo motor, please make a clear

indication in the order.

2 Temperature and Humidity

The environmental temperature shall be kept between -10 and 40 . After long hours of operation, the motor will have an increasingly hot temperature, so compulsory heat radiating shall be considered when the surrounding space is relatively small or there are heating equipment.

The humidity shall not be more than 90%RH, without dew condensation.

3 Vibration

Servo motor shall not be installed at places with vibration. The vibration inflicted on the motor shall not be more than 0.5G (4.9m/s2).

2)Installment Methods

(1)Ways of Installment

Currently, SJT and ST series of motors adopt the way of installment by the flange with arbitrary installment direction.

(2)Notes:

zWhen dismantling or installing the belts and wheels, shock on the motor or motor shaft shall be forbidden to prevent the encoder from being damaged. Screw pressing tools shall be employed in the dismantlement or installment.

zCurrently, most of the SJT and ST series of motors cannot bear shaft-direction or radial-direction loads. Coupling is recommended for connecting the loads.

zWhen fastening the motor, the anti-loosening washer shall be used to prevent the motor from loosening.

Chapter Three Wiring

Warning

Personnel involved in wiring or examination must possess sufficient abilities in this task.

●Wiring and examination must be conducted 5 minutes after the power is off for preventing electric shock.

Attention

The wires must be connected according to terminal voltage and electrode to prevent the equipment from being damaged or personnel from being hurt.

● The drive unit and servo motor must have good ground contact.

3.1 Standard Wiring

10

DA98D User Manual

zPlease install surge absorbing elements in sensible elements (loop) in related circuits: DC loop is reversely connected in parallel with continuous current diode while AC loop is connected in parallel with capacitance-resistance absorbing return circuit.

Attention

U, V and W shall be connected with motor winding in the way of one-to-one correspondence. Reverse connecting shall be forbidden.

The wires and leads shall be fastened firmly and avoid approaching radiator of the drive unit and the motor for the fear that the insulation performance will be reduced due to heat.

There will remain large quantities of electrolyzed capacitance in the servo drive unit, so there will a high remaining voltage even after the power is cut off. Do not touch drive unit or motor within 5 minutes after the power is off!
