2> Apply magnetic circle on the communication wire.

3> Reduce inverter carrier wave frequency properly.

note

(1) When form the network only by inverters, you must set local address parameter F2.15 of the mainframe EDS800 to 0.

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

3.7 Installation guide for anti-jamming

Main circuit of the inverter is composed of high-power semiconductor switch gear, so some electromagnetic noise will arise during work,to reduce or stop disturbance to environment,show you assembling method of inverter disturbance suppressing from many aspects such as disturbance suppressing, spot wiring, system grounding, leak current, usage of power supply filter etc. in this section to be referred to during spot assembling.

3.7.1 Restraining to noise disturbance

Disturbance brought by the working inverter may affect nearby electronic device, effect degree relates to surrounding electromagnetic environment of the inverter and anti-disturbance capacity of this device.

(1) type of disturbance noise

According to work principle of the inverter, there are mainly 3 kinds of noise disturbance source:

1> circuit conduction disturbance;

2> space emission disturbance;

⑥⑦⑧

When grounding wire of peripheral device and wiring of the inverter compose closed-loop, inverter grounding wire leakage current would make the device do wrong action. Can reduce wrong action if the device is not earthed here.

High-order harmonic from the inverter would make voltage and current transmit through power supply wire when peripheral device and the inverter electrified by same power supply, would disturb other devices in this same power supply system,can take following suppressing measure: assemble electromagnetic noise filter at inverter input end;isolate other devices by isolation transformer; connect power supply for peripheral device with remote power source; install ferrite filter magnetic circle for L1, L2, L3 three-phase conducting wire of the inverter to suppress conduction of high-frequency harmonic current.

Keep device and signal wire prone to disturbance from the inverter. Should use shielded signal wire, shielding layer single end earthed and try best to keep away from the inverter and its input, output wire. If signal wire must intersect strong power cable, must keep them in real intersection and avoid parallel.

Install high-frequency noise filter(ferrite common module choke, folksay magnetic circle) separately at input, output root,which can effectively suppress emission disturbance from dynamic wire.

Should place motor cable shield of biggish thickness, for instance set it in tube with biggish thickness (above 2mm) or bury it in cement slot. Dynamic wire set into metal tube and use shielding wire to be grounded (use 4-core motor cable, one side is earthed through the inverter, the other side connected to motor shell).

To prevent parallel or bundled power and weak conducting wire;should keep away from inverter mounted device to the best and its wiring should keep away from power wire of the inverter such as

L1, L2, L3, U, V, W etc.. Should pay attention to relative mounting place between device with strong electric field or strong magnetic field and the inverter, should keep distance and vertical intersection.

3.7.2 Local wiring and earthing

(1) Avoid parallel cable from inverter to motor (U, V, W terminal education wire) and power supply wire (L1, L2, L3 terminal input wire). Should keep distance of 30cm above.

(2) Try your best to place motor table from U, V, W terminals in metal tube or metal wiring slot.

Power supply wire or motor cable

(3) Should use shielded cable as common control signal cable,shielding layerclose-to–inverter side

Control signal cable earthed after connected with PE terminal of inverter.

Fig.3-16 system wiring demand

(4) Cable educed from inverter PE terminal must be connected directly to earth-plate and can’t be connected to ground through grounding wire of other devices.

(5) Powerful cable(L1, L2, L3, U, V, W)should not parallel control signal cable closely, say nothing of being bundled together, must keep distance of 20~60cm

22

EDS800 series Service Manual above (related to size of powerful current). Should cross each other vertically if intersection, as Fig.3-16.

(6) Powerful grounding wire must be connected to earth separately from weak grounding cable such as control signal and sensor cable etc.

(7) Forbid to connect other electricity consumption device to inverter power supply input end(L1,

L2, L3).

3.7.3 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.

3.7.4 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. 3-17. diode

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.

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.

Appendix 2 Braking resistance

1.1 Braking resistance

The motor’s electric potential energy will charge inverter’s capacitance up reversely if speed of the motor decends 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.

EDS800-2S0002~EDS800-2S0015 have built-in braking unit,you can add external braking resistance ,but the external resistance need booking.
