Fig. 3-11 recommended wiring for multiple inverters communication (all inverters and motors well earthed)

Normal communication still not available if using above wiring, can try to

16

Tel/Fax:86-755-26984485/26985120 3 Installation and wiring

note take following measure:

1> Provide separate power supply for PLC (or upper machine) or isolate its power supply.

2> Apply magnetic circle on the communication wire.

3> Reduce inverter carrier wave frequency properly.

(1) When form the network only by inverters, you must set local address parameter

F2.15 of the mainframe EDS-A200 to 0.

(2) For programming of RS485 interface,please refer to appendix communication protocol.

3.6 Relation of long-distance wiring and current leak and the countermeasure

High-order harmonic will form between-line leak current through distributing capacitor and to-earth leak current when long-distance wiring between inverter and motor commence. Can adopt following method to suppress:

(1) install ferrite magnetic circle or output reactor at inverter output side.

!

End voltage of the motor will be reduced markedly when installing reactor of 5% above rated voltage dropn and make long-distance wiring to U, V, W. Fully loaded motor have the danger of burning itself, should work in lower volume or step up its input output voltage.

(2) Reduce carrier wave frequency but motor noise would increase accordingly.

3.7 Installation demand for electromagnetic on-off electronic device

Relay , magnetic control conductor and electromagnetic iron and so on, these electromagnetic on-off electronic device would bring lots of noise during work, so you should pay full attention to when installing them beside the inverter or in the same control chamber with the inverter and must install surge absorbing device as shown in

Fig. 3-12.

4.1 Run of inverter

4.1.1 Running order channels

There are 3 kinds of order channel for controlling run action of the inverter such as run, stop, jog etc.:

0: Keypad

1: Control terminal

Use control terminal FWD, REV, COM to make of double-line control,or use one terminal of X1~X5 and FWD or REV to make of three-line control.

2: Serial port

Control run and stop of the inverter through upper machine or other device which can communicate with the inverter.

Choose order channel by setting function code F0.02;and also can choose by multi-function input terminal(F5.00~F5.07 choose function 29, 30, 31).

!

Please make switching debugging in advance when switch the order channel to check if it can fulfil system requirement,otherwise have danger of damaging device and injuring personal.

4.1.2 Frequency-provision channel

Under EDS-A200 common run mode there are 9 kinds of provision channel:

1: closed-loop run

The inverter will come into closed-loop run mode when closed –loop run control effective parameter is set(F3.00=1). Namely carry on PID adjustment to specified value and feedback value(proportion integral differential

19

Tel/Fax:86-755-26984485/26985120 4 Run and operation explanation for inverter calculation, see F3 group function code) and PID adjustor output is inverter output frequency. Can make closed-loop run mode ineffective and switch to lower level run mode by multi-function terminal (function 20).

2: PLC run

The inverter will enter into PLC run mode and run according to run mode preset(see F4 group function code description) through setting PLC function effective parameter(F4.00 last bit≠0). Can make PLC run mode ineffective and switch to lower level run mode by multi-function terminal (function 21).

3: Multi-section speed run

By nonzero combination of multi-function terminal(1, 2, 3, 4 function), choose multisection frequency 1~15(F2.30~F2.44) to run at multisection speed.

4: Traverse run

The inverter will enter into traverse run mode when traverse function effective parameter(F6.00=1)is set. Set relevant traverse run special parameter according to textile traverse craft to realize traverse run.

5: Common run

Common open loop run mode of general inverter.

In above 6 kinds of run mode except “jog run” the inverter can run according to kinds of frequency setting method. In“PID run”“PLC run”“multisection run”“common run”mode the inverter can also carry on pendular frequency adjustment.

Actual descending rate of motor speed may be lower than that of output frequency due to effect from load inertia when the inverter is in decelerating run process, here the motor will feed electric energy back to inverter which will make DC bus-bar voltage of the inverter increase, overvoltage protection will takes place if not take steps. Overvoltage stall protection function, indicates that output frequency of the inverter stops descending if bus-bar voltage detected during run process exceed stall voltage point defined by F9.08 (relative to standard bus-bar voltage) and the inverter continue to implement decelerating run when bus-bar voltage detected again is lower than stall overvoltage point.

By automatic current limiting function the inverter can limit load current not to exceed automatic current limiting level set by F9.09 to avoid tripping out for failure caused by rushing current. This function is especially suitable for some biggish inertia or acutely changing load occasion.

Automatic current limiting (F9.09) defines current threshold value of automatic current limiting action, its value is the percentage relative to inverter rated current.

92

Tel/Fax:86-755-26984485/26985120 6 Detailed function description

Frequency descending rate during current limiting (F9.10) defines adjusting rate to output frequency during automatic current limiting action.

If frequency descending rate during automatic current limiting F9.10 is too small,inverter isn’t easy to get rid of automatic current limiting state which may cause overload failure finally;If descending rate F9.10 is too big, the inverter may be in generating state for long time which will cause overvoltage protection.

Automatic current limiting function is effective in accelerating decelerating state and whether it’s effective in constant speed run state is determined by automatic current limiting action selection (F9.11).

F9.11=0 indicates that automatic current limiting is ineffective during constant speed running;

F9.11=1 indicates that automatic current limiting is effective during constant speed running;

Output frequency may varies during automatic current limiting action,so automatic current limiting function is not suitable for occasion demanding stable output frequency during constant speed run.

1.4 RTU Communication Mode

1.4.1 Data frame format

Using RTU mode, messages are sent at least 3.5 character time interval pause. The first transmitted field is device address, the character you can transfer is hexadecimal

0x00 ~ 0xFF. Network equipment Continuously monitor the bus, including pauses.

When the address field is received, all equipment determine whether it is sent to their own. when the last character of the packet transfer is complete, at least a 3.5 character times pause mean the end of the message. A new message can begin after this pause.

The entire message frame must be transmitted as a continuous flow. If a new message start transmitting in less than 3.5 character times after a message and then receiving device will consider it a continuation of the previous message. This will cause an error, because in the final CRC field value can not be right.

The motor’s electric potential energy will charge inverter’s capacitance up reversely if speed of the motor descends too quickly or load of the motor wobbles too quickly while the inverter is running, which will increase the voltage upon power modules suddenly and is easy to make the inverter damaged. The inverter will control it according to load size and performance.

You have to connect external resistance to realize timely energy discharge when the braking is not enough. To connect external resistance is a kind of energy consumption braking mode, as all the energy is consumed by the braking resistance.

You can add external braking resistance when the application need them ,but the external resistance need booking.
