2.1 Installation environment

To ensure perfect performances and long service life, it is recommended to install

the DS5servo drives in the following environments, so as to prevent damage to the drives.

Notes

1. It should be protected from direct exposure to sunlight and not be used outdoors.

2. It should not be used in any environment with corrosive gas or a liquid environment.

3. It should not be used in any environment with oil mist or water spray.

4. It should not be used in any salt spray environment.

5. It should not be used in any environment exposed to rain or any damp

environment.

6. When it is used in an environment with metal powder or silk spinning fiber

floating in the air, a filter should be additionally installed.

7. It should not be used on any occasion when there is mechanical impact or

vibration.

8. When the ambient temperature is over 55ºC, measures should be taken to bring

the temperature down before it is used.

9. The equipment may fail when it is too cold or too hot. It is suggested using the

equipment under the temperature between -20ºC and +55ºC.

10. It should be kept away from power noise. For example, welding machines or

large-power electric equipment may impact on operation of the equipment.

11. The equipment is subject to radioactive materials.

12. The equipment should be kept away from combustibles, diluents and solvents.

2.2 Drives installation

(1) As shown in the following figure, it is recommended to install the equipment perpendicularly to

the wall, with sufficient space (above 200mm) left for ventilation and wiring operation .

(2) Use natural convection or a ventilator to cool the servo drives.

(3) Please fix the servo unit firmly on the installation surface by using the four installation holes.

(4) When multiple drives are installed in one cabinet:

(a) Please keep front surface of the servo drives (the installation surface of LED panel) facing the

operator.

(b) To ensure cooling by a fan or natural convection, attention should be paid to where the

ventilator in the cabinet should be installed; improper location of the ventilator may result in

temperature rise around the drives, and further affect the cooling effect on the drives.

(c) When parallel installations are carried out, space of above 50mm on the two sides in the

horizontal direction should be reserved, above 200mm on the two sides in the vertical direction

should be reserved. Additionally, a cooling fan should be installed at the upper part of the servo

unit. To avoid local overhigh temperature of the servo unit, temperature in the control cabinet

should be kept even.

2.3 Servo motor installation

To ensure safe and stable operation of the servo motor, please install the motor in

accordance with the following instructions.

Notes

1. The servo motor can be installed in the horizontal or vertical direction.

2. When the motor is connected to another machine, it is recommended to use

coupling, and keep the axis of the servo motor in a straight line with the axis

of the machine. When the servo motor is installed, if the concentricity is

insufficient, vibration can be produced, and further damage will be incurred

to the shaft or encoder etc.

3. The series of servo system requires positioning for installation of feedback

elements (optical encoder, resolver), i.e. it is required that the positions of

feedback elements are fixed relative to the rotor and stator of the motor, and

users may not remove or replace such elements at discretion.

4. Do not apply tensile force on the wire, particularly the signal wire with fine

core. Therefore, the wire should not be stretched too tight upon wiring (use).

5. Upon installation of the motor, direct impact on the shaft should be avoided

to prevent damage to the precise parts (optical encoder, resolver) on the shaft

or degradation of precision.

Procedures for installation of the motor and pump:

(1) Connect the flat key with the pump, put half of the coupler on and set the bolts

but not tighten them.

(2) Connect the flat key with the motor, put the other half of the coupler on, and

set the bolts but not tighten them.

(3) Connect the pump to the motor frame, and tighten the bolts when the direction

is determined.

(4) Connect the motor to the motor frame, and tighten the bolts when the direction

is determined.

(5) Adjust the flexible coupler clearance to 2-3mm, and tighten the bolts on both

ends; rotate it manually, and there should be no abnormal noise.

(6) Place connecting pieces of the motor, motor support and pump at the

installation positions; the screw holes for fixing the motor frame will be

drilled on site.

(7) Then tighten the bolts.

3. Electrical Connections 3.1 Notes for wiring

Warning

1. Wiring can be only done by special workers. Improper wiring may result in electric shock or fire.

2. DS5servo drives can be directly connected to a power cable for industrial use, without separation of a transformer; to prevent cross electric shock accident in

the servo system, a circuit breaker or fuse for wiring should be used.

3. DS5servo drives has no built-in grounding circuit for protection. To form a safer

system, please configure a leakage circuit breaker with protection against both

overload and short circuit, or a special leakage circuit breaker supplied along with

the circuit breaker for wiring.

Notes 1. It is suggested using the grounding method A, B or C (with the grounding

resistance of below 10Ω). One-point grounding should be adopted. When the servo

motor and the mechanical firmware are insulated to each other, please ground the

servo motor directly.

2. The grounding wire should be thick (above 2.0 mm2).

3. Most leakage circuit breakers on the current market are electronic leakage circuit

breakers, and breakers from different manufacturers differ greatly in the internal

leakage current detecting and processing circuits, resulting in different resistances

of the breakers to interference. For this servo drives, users are suggested using leakage circuit breaker with relatively strong resistance to interference. To this

point, Zhengtai leakage circuit breaker is recommended for its strong resistance to

interference.

4. Upon wiring, the power cable, the servo motor input line and other strong current

lines should be separated from the signal line, with intervals of above 30cm, and

should not be placed in the same duct or bound together.

5. It should not share the same power source with any welding machine or electric

discharge machine. Even if it does not share the same power source, when there is a

high-frequency generator nearby, a filter should be connected at the input side of

the power cable.

6. Surge arresters must be installed on the coils of the relay, solenoid and

electromagnetic contactor.

7. To prevent misoperation caused by electromagnetic interference, the command

input device and the filter should be configured nearby the servo unit wherever

possible.

8. Reasonable wire diameter, switch capacity and contractor capacity should be

selected. See “Selection of switch, contractor and wire diameter”.

※ Improper wiring may result in system failure or potential hazards to personal safety.

temperature is below 40 degrees with the wiring distance of less than 10 meters. In case of

higher ambient temperature or greater wiring distance, larger wire dimension is

recommended. 600VIV plastic insulated wire is recommended.

Note 5

Note 1:in the wiring diagram, the digital input signal uses the power of the control

system; the 24V power terminals on CN1 and CN3 connectors are connected to an

external power; the user may also use the pressure sensor power inside the drives,


- 23 -

connecting to the terminals CRF and AGND.

Note 2:the pressure sensor power of the drives is 15V; the received pressure signal is

0~10V or 1-5V voltage signal, which can be set via the dial switch J9 on the control

panel. For details, see 4.8.1 Interface of the analog input circuit.

Note 3:to prevent undesired signal impacting on the drives, it is suggested that

shielded cables be adopted for all analog signal drives lines and 3-phase input lines of

the motor, with the shielding layer grounded.

Note 4:for the resolver lines and communication lines, shielded twisted pair cables

must be used, with the shield grounded. Both ends of the communication line should

be connected with resistors. The CAN communication signal connector of the drives

herein has a built-in 120-ohm terminal resistor, which can be connected or

disconnected from the bus with a jumper. When the user is using a parallel

multiple-pump system, it is required to connect the CAN communication lines at both

ends of the drives to the terminal resistor. See 4.7.2 CAN communication signal

connector (CN6) for the designations and functions.

Note 5:to prevent undesired signal impacting on the drives, twisted pair cables are

recommended. This drives supports two kinds of motor temperature sensor for

temperature sampling, i.e. KTY84 and Pt1000. Through the jumper SW1 on the

power panel, the type of temperature sensor supported can be selected; when in the

dial switch “KINWAY” is turned to ON and “Others” is turned to OFF, the drives

supports Pt1000 temperature sensor; when in the dial switch “KINWAY” is turned to

OFF and “Others” is turned to ON, the drives supports KTY84 temperature sensor. It

is not allowed to have both ON or both OFF.

Note 6: terminal AGND can directly connect to PE via jumper J8 on the control panel

or connect to the capacity through a resistor. When the middle PIN of J8 and the side

PIN of GND are short-circuited, connection to PE is applicable

to DS5T020-SKG, DS5T030-SKG and DS5T040-SKG drives. When the middle PIN

of J8 and side PIN of C are short-circuited, connection to PE is applicable

to DS5T060-SKG, DS5T075-SKG and DS5T100-SKG drives.

Note 7:when the analog output and digital output ports are used, it should be ensured

that there is a sufficiently large output load resistor to control the output current under

the specified value.

6. Motor Parameter Self-learning

- 51 -


The motor parameter self-learning function is necessary when in-situ replacement of

the drives motor concerns a model not listed. Motor parameter self-learning can be

executed in two modes:static and dynamic.

In the static mode, the motor parameter values, i.e. resistance, inductance and flux

linkage, will be obtained through the motor voltage equation based on the motor nameplate

parameters. Hence precision of the motor parameters depends on precision of the nameplate

parameters.

In the dynamic mode, it requires the motor to rotate at a certain speed, and load has

great impact on precision of motor parameter testing. Hence, during testing, the motor runs

free from load or with light load.

Motor nameplate parameters and parameter self-learning mode:

F70 Rated voltage of the motor [0,800] V

F71 Rated current of the motor [0,900] A

F72 Rated rotating speed of the motor [0,6000] Rpm

F73 Rated frequency of the motor [0,600] HZ

7.2 failure source analysis

As shown in the following figure, the INVT injection molding machine mainly

consists of such key components as the permanent magnet synchronous motor, the motor

rotor position/speed sensor (resolver), the servo drives, the oil pump with coaxial

connection with the servo motor, and the pressure sensor for testing the oil pressure of the

system.


- 56 -

Strictly speaking, all components in the above block diagram (including the

connecting lines) can be regarded as failure sources. See the following figure for failure

distribution of the system:

No-scale signal Output or

unstable output; no enabled

signal output or unstable output;

the upper computer works

abnormally due to interference.

THe control panel fails;

the power supply panel

fails; the resolving

plate fails; the software

fails; the braking

resistor fails;

Revolving wire failure;

temperature line failure

Shaft damaged;

temperature-measuring

resistor damaged; resolver

damaged; wiring short-

circuited to the ground;

wiring short-circuited;

motor demagnetized.

Leakage: the

hydraulic oil

contains air.

Pressure sensor damaged;

oil hole blocked; wire

disconnected

Bad grounding: electric parts

cannot work normally due to

interference; the thermocouple is

short-circuited to the ground;

filter element clogged; bad

assembly of the coupler;

improper leakage protection

switch selected.

To be familiar with the failure distribution may facilitate systematic and overall

analysis of faults, so as to locate the failure sources fast and accurately.

7.3 Reasons for protection and countermeasures

In case of an alarm code fault, the panel will display the failure code. The failure code

display and countermeasures are shown as follows. If the failure cannot be eliminated after

the countermeasures are taken, please contact the agent or the service department of our

As the servo drives has no braking resistor inside, an external braking resistor must be

connected. When a braking resistor with larger power is required for more frequent braking

of the motor, the user may select a braking resistor with lower resistance and higher power.

The external braking resistor should be installed at a place with good ventilation and far

from combustibles or parts not resistant to heat.

When selecting an external braking resistor, the user should note that the resistance

value of the braking resistor should not be lower than the specified value; or otherwise it

may cause damage to the drives.
