CHAPTER 1 OVERVIEW

1.1 Product Introduction

The AC servo drive unit (all digital AC drive unit with high precision and high speed) of DAH series (including DAH01 and DAH2075E) is a new generation of high-precision and high-speed AC servo product produced by our company. It can be used together with various open-loop and closed-loop control systems. The servo unit uses an international advanced special chip for motor control (TMS320F2812PGFA DSP), a large scale programmable gate array（CPLD/FPGA）and an

IPM intelligent power module. It is of high integrated level, small dimension, safe protection and high reliability. Its performance has reached the advanced level of similar foreign products, for an optimal PID algorithm is used to complete PWM control; besides, it can intelligently identify various servo motor models and has parameter auto setting function. Its servo motor uses a 17 bits high-precision absolute encoder. The servo drive unit of the series can be applied to mechanical manufacture, CNC machines, printing and packing machines, textile machines, robots, automatic manufacturing lines and other automation fields.

DAH series AC servo unit has the following advantages:

z Using the most advanced 32-bit DSP processor (F2812) of TI Company to shorten signal

processing time and improve current sampling precision. System processing capability has been

greatly improved due to the 150MIPS of frequency of F2812. z The system uses a 17-bit absolute encoder with 131072 lines. Compared with incremental

encoders, absolute encoders are characterized by high positioning precision, strong

anti-interference ability, motor rotor position memory and convenient installation. z Bus communication uses GSK-LINK communication mode, which can fully meet the control

requirement of more than five axes. Up to 254 servo drive units can be connected theoretically,

and data transmission rate is 100Mbit/s；

z Fully closed loop control between CNC and servo unit, on-line upload and download of servo

parameters, diagnostic message feedback of the servo and servo alarm monitoring can be

realized in bus communication mode; memorizing workpiece coordinate system after power-off

and returning to zero point without a stroke limit switch are realized too; z Analog instruction interface uses a high–precision A/D (16 bits) convertor. It has strong

anti-interference ability and small zero drift. z High speed and high precision: a servo unit can drive a servo motor of 6000r/min; speed ratio: 1：

60000; it has stable torque characteristics from low speed to high speed; rotary positioning

precision: 0.0762μm；

z Intelligent identification for motor models and auto-setting control for parameters: DAH series AC

servo unit intelligently reads various models and parameters into the servo unit when power is

turned on. When a motor is replaced with the one of different model, its corresponding default

parameter can be resumed automatically; in different load inertia ratios, it can accurately identify

system control models and has parameter auto-setting function.

Simple and flexible control: set the operation mode and operation characteristics of the servo

drive unit by modifying parameters to meet different requirements.

3） Heat Dissipation

To prevent the ambient temperature of the servo unit from rising continuously, radiators blowing

convection wind towards the unit should be installed in the electric cabinet.

Chapter 2 Installation

2.3 Installation for Servo Motor

Note

1） Installation Environment

（1） Protection

Prevent liquid from spraying to the motor and prevent oil and water from entering the motor through its lead-in wire and motor shaft, for the servo motors of GSK SJT series and Huazhong ST series are not water-proof.

Note: Please declare in your order if you need a water-proof motor.

（2） Temperature and Humidity

Keep the environment temperature between 0～+40 . Motor temperature rise℃ s after

long-term running, so forced air cooling should be taken when there are heating elements or small space around the motor.

Relative humidity should be less than 90%RH，with no dewing.

（3） Vibration

The servo motor should not be installed in the situation with vibration, and the vibration

should be no more than 0.5G (4.9m/s2）。

2）Installation Method

(1) Installation Method

SJT series motor adopts flange installation mode currently and its installation direction is arbitrary.

(2) Cautions: z It is forbidden to strike the motor or motor shaft to prevent the encoder from being

damaged when disassembling or assembling belt wheels.

z Most SJT series motors can not bear big axial and radial loads currently. It is suggested

that elastic couplings be used to connect loads.

z Fix the motor with anti-loosened gaskets to prevent it from coming loose.

CHAPTER 3 CONNECTION

Caution

 Only qualified persons can connect the system or check the

connection

 Wiring and checking cannot be done in 5 minutes after the power

supply is switched off to avoid electric shock.

 Wiring must be performed in terms of the terminal voltage and

polarity to avoid equipment damage and personnel injury.

 The drive unit and servo motor must be grounded well.

3.1 Standard Wiring

1） Ethernet Bus Mode

Figure 3-1-1 and figure 3-1-2 show the Ethernet bus standard wiring for DAH01 and

DAH2075E respectively.

2） Position Control Mode (Pulse Mode)

Figure 3-1-3 shows the standard wiring for position control (pulse mode).

3) Speed Control Mode (Analog Voltage Mode) Figure 3-1-4 shows the standard wiring for speed control (analog voltage mode).

4) Wiring

（1） Power Terminal TB

z Wire cross-sectional area: For terminals R、S、T、PE 、 U 、 V and W, cross-sectional

area≥1.5mm2(AWG14～16); for terminals r and t, cross-sectional area ≥1.0 mm2(AWG16～

18).

z Grounding: grounding wires should be as thick as possible. Drive unit shell, servo motor and

system shell are earthed at one point of PE terminal. Earthing resistance ＜0.1Ω.

z Terminal connection adopts SVM2-4 pre-insulated cold-press terminals which must be

connected securely.

z It is suggested that the power be supplied through a three-phase isolation transformer to

reduce the possibility of electric shock.

z It is suggested that the power supply through connecting a noise filter to improve

anti-interference capability.

z Please install a non-fuse breaker (NFB) to cut off the power in time when a fault occurs in the

drive unit.

Control Signal CN1 and Feedback Signal CN2

z Wire selection: use screen cables (twisted ones are recommended ), Cross-sectional area

≥0.12mm2(AWG24～26)，shield layer must be connected to FG terminal.

z Wire length: wires should be as short as possible, the wire for controlling CN1 should not be

longer than 3m, and feedback signal for controlling CN2 should not be longer than 20m.

Chapter 3 Connection

z Wiring: wiring should be far from power circuit to prevent interference. z Please install surge absorbing components for inductive components (coil): DC coil

connects to the freewheel diode in parallel back to back while AC coil connects to the RC absorbing circuit in parallel.

z Bus interface connecting wire uses UTP- five categories (network cable) with both ends

suppressed with crystal heads. Direct network cable and cross network cable can be suppressed.
