Foreword

Thanks for using AC90 tension control frequency inverter produced by Shenzhen Veichi Electric Co.,Ltd..

AC90 tension control frequency inverter is is a special high-performance vector tension control inverter developed by

our company recently. It adopts advanced torque mode open loop tension control technology. It is not only an

international leader in motor control performance, it also combines tension control industry characteristics, which further

strengthened the product reliability, stability and ease of debugging, can to better meet the demand in the field of

tension control.

This product is to keep constant tension by the output torque control and automatic roll diameter calculation. The

system does not need to install a tension sensor, no need to feedback of the external signal of the current position, or

the tension. It is able to complete the tension control even without need to install speed feedback rotary encoder in most

applications.

To meet the needs of different customers, the product provides two basic control modes. Control modes including:

1: Speed control mode

Inverter controls the speed of the motor by controlling the output frequency. The output torque of the motor is decided

by the load side, but will be limited in the maximum output torque. It is applicable to all types of speed purposes.

2: Torque control mode

The target of the inverter is to control the motor output torque. The motor speed is decided by the load side, but will be

limited in the setting frequency. In this mode, the user can set the tension value, and make tension open-loop control

coming true through the inverter diameter calculation function.

In tension open-loop control, roll diameter calculation is a very important part. Inverter has three roll diameter

calculation methods:

A: Linear speed method.

means linear speed of traction side; means The angular velocity of the rotation of the motor; means

mechanical reduction ratio; means winding roll diameter.

B: Thickness calculation method.

Accumulate the diameter according to the material thickness and cycles of the roll rotation to gain the roll diameter.

C: Time calculation method

Time integral method needs the time from empty roll to full roll, torque for empty roll and torque for full roll. Inverter will

increase torque giving value according to the change of the roll diameter and time.

AC90 tension control inverter can completely replace the torque motors, DC motors, tension controller and be

independent tension control system, which makes the control system more concise, easier to maintain and with better

tension control performance. It is suitable for application to paper, paper processing, printing and dyeing, packaging,

wire and cable, optical fiber cable, adhesive tapes, textile, leather, metal foil processing, fibers, rubber and other

industries.

Chapter 3 Installation and Wiring

3.1 Safety Precautions

This chapter explains the warnings for safe use and stable running of the product.

Cautions in use

●While stall the inverter in the closed cabinet, please build in cooling fan, air-condition or other

cooling equipments to ensure the temperature at the air-in port below 40℃. So that the

inverter can work safely and reliably.

●While installing, please use cloth or paper cover the inverter to prevent metal dust, oil, water

and others.And remove it carefully after working.

●While operation, please follow the ESD regulations. Otherwise, the inverter may be damaged.

●While multi inverters are installed in the same cabinet, enlugh space must be left for cooling

fan.

●Inverter can not work over rated range.Otherwise, the inverter may be damaged.

●While transporting the inverter, please hold the firm case. If only hold the pre-cover, there is

danger of inverter main body falling, injury or inverter damage.

Cautions in use motor

●Different motor has different max allowable running speed. Motor can not run over the max

allowable running speed.

●While inverter is running at low speed, the motor auto-cool effect is seriously worse. If motor

runs at low speed for long time, it will be damaged for overheat. If needed, please use special

motor for inverter.

●While constant speed machinery runs at unconstant speed, there maybe sympathetic

vibration. Please install vibration-proof rubber under motor rack or use jumping frequency

control function.

●While using frequency inverter or working frequency power supply to drive, the torque

characteristic are different. Please do confirm the torque characteristic of the equipment

connected.

●The rated current of shift gear motor is different from that of standard motor. Please confirm it

and choose the right frequency inverter. Moreover, please do switch the pole while the inverter

input current is 0. Otherwise it may bring inverter protection or damage.

●The rated current of diving motor is higher than that of standard motor, please confirm it and

choose the right inverter.

●While the wire between motor and inverter is long, the max torque of the motor will reduce for

voltage drop. So please use thick cable while the distance between the motor and the inverter

is long.

3.4 EMI Protection

The inverter is designed to be used in industrial environment with strong electromagnetic interference. Generally

speaking, if the installation quality is good, it is ensured that the inverter can work safely without fault. Please install the

inverter according to the following rules to ensure stable running and avoid electromagnetic interference impact.

● Ensure that all equipments in the cabinet have been connected reliably to the common Y-type earth point or earth

bus with thick and short cable. The motor earth should be as close as possible. Please do not connect the motor

case to the inverter earth terminal or the protective area of control system.

● Ensure that all equipments connected to the inverter have been reliably connected to the same earth net or Y-type

earth point with thick and short cable.

●The conductor has better to be flat and with multi core, what has lower resistance at high frequency.

●The cutting terminal should be as soigne as possible. Unshielded wire section must be as short as possible.

●In control cable wiring, it should be as far from the power supply cable and motor cable as possible. And independent

cable trough should be used. While the control cable must cross to the power supply cable or motor cable, it should

be 90º vertical cross.

● Ensure that the contactor in the cabinet has wave surge suppresser. Or‘R-C’damping circuit is connected to the

winding of AC contactor. Voltage dependent resistor corresponding to the winding voltage is used. And freewheel

diode or components such as voltage dependent resistor corresponding to the winding voltage are connected to DC

contactor. It is very important while contactor, controlled by output relay of inverter, acts frequently.

● Cable connected to motor should be shielded cable or armoured cable. The two barriers are earthed reliably by

cable grounding card.

● Build noise filters at the input side to reduce electromagnetic interference from other equipments at the power grid

side. The noise filter should be as close to the inverter power input terminal as possible. Meantime, the filter must

earth reliably as the inverter.

AC90 TENSION CONTROL FREQUENCY INVERTER MANUAL BASIC OPERATION AND TRIAL RUN

11

● Build noise filters at the output side to reduce radio interference and inductive disturbance. The noise filter must be

as close to the inverter output terminal as possible. Meantime, the filter must earth reliably as the inverter.

●Anytime, control circuit wire should be shielded cable.

●Add zero phase reactor in power supply wire near inverter input terminal and add zero phase reactor in the motor

wire near inverter output terminal to reduce electromagnetic interference to the inverter efficiently.

● Earthing Right and reliable earthing is the basic condition of safe and reliable running of the product. For right

earthing, please read the following notice carefully.

●In order to avoid electric shock, earthing cable should be the size as electric

equipment technic standard required and cable length should be as short as

possible. Otherwise, inverter leakage current will cause unstable potential of the

earthing terminal which is far from the earthing point, and electric shock accident will

happen frequently.

●Earth terminal must be earthing. Earth resistance must be below 10Ω. Otherwise,

there is danger of death.

● Please do not share earth cable with welder or other big current/pulse power

equipment. Otherwise, inverter will act abnormally.

●While multi inverters are used at the same time, please do not wind the earth wire to

loop-type. Otherwise, inverter will act abnormally.

Chart 3-4: multi AC90 series inverters united earthing

Chart 3-5：AC90 series inverter system earthing

Remark: motor must earth as close as possible. Motor case can not be connected to the inner earth terminal of the

inverter. It also can not share the earth net with the control system.

Shield of inverter power cable, motor cable, control cable Cable

Shielding layer (reticulate/armoured) should be winded reliably by cable earth card and fix to inverter earth piece by bolt.

Please refer to the following chart.

Chart 3-6：Cable earth card for cables earthing

●Corresponding relationship between inverter/motor cable length and carrier frequency.

While cable distance between inverter and motor is long (especially low frequency output), cable voltage drop will make

motor torque reduce. Further more, cable HF leakage current will increase. Then inverter output current will increase,

that will cause inverter over-current trip. The current detection accuracy and running stability will be impacted. Please

follow as below chart to adjust carrier frequency according to the cable length. While the cable distance is over 100m,

please adopt distributed capacity reduce measure (Such as “no metal conductor covers cable”, “wire each phase cable

apart” and so on).

Cable length <20m 20~50m 50~100m >100m

degrees and inserts the top fixed flat into the fixed hole in

the front cover. Then slightly press the tail-hood downward.

While your hear "Ka", it means that the tail-hood is into the

place.

Chart 3-15:AC90 series inverter tail-hood installation

Dismantlement: At the tail of the frequency inverter, there

is a special dismantlement hole design. Put your finger into

the hole, upwardly pull the cover with a little force until the

buckle between the tail-hood and the crust tear off, and then

remove the tail-hood down.

3.6 Electric installation

This chapter explains the regulations that users have to obey to ensure safe use, best performance and reliable

running.

Safety attention

● Must earth reliably while inverter is running. Otherwise there is danger of casualty and

unstable inverter performance.

● To ensure safe running, only trained professional person can do installation and wiring

job.

● No operation under power connected state. Otherwise there is danger of electric shock

even death.

● Before operation, please cut all related equipments power, ensure that the main circuit

DC current has droped to safe range. And please operate after 5 mins.

● Control cable, power cable and motor cable must be separated. They can not be in the

same cable trough or cable rack.

● This equipment can only be used as the maker states. Please consult Veichi while using

in special case.

● No insulation test for the inverter or the related cable by HV insulation test equipment.

● If the inverter or the peripheral equipment (filer, reactor and etc) needs insulation test,

firstly 500V megohmmeter should be used to test the insulation resistance which should

not be lower than 4MΩ.

Note: 1.While install DC reactor, be sure to dismantle the short connector between terminal P1 and（+）.

2.NPN or PNP transistor signal can be selected as input of multi-function input terminal（X1~X8）. Inverter

built-in power supply (+24V terminal) or external power supply (PLC terminal) can be choosed as bias

voltage. Factory setting ‘+24V’ short connect with ‘PLC’.

3. Analog monitor output is special output of meters such as frequency meter, current meter, voltage meter

and etc. It can not be used for control operations such as feedback control.

4. As there are multi pulse styles, please refer to the line connect mode description details.
