Pn 33 Software version

Pn 34 Auto recover while lost power suddenly0 disable this function 99 means do auto recover in infinite time, starting from low frequency Other value:

If indicator displays LU-X(any code) during runtime and power source recovers in 2 seconds, inverter would start up again and reduce runtime frequency with magnitude of under voltage time(s) multiply frequency of this component(Hz).

The maximum power lost time is 2.5s. Beyond this time, it would be seen as over voltage without any auto recover.

8. Operation Examples

8.1 Operation by panel

Pn 04 = 1 (Command from panel), Pn 03 = 1 (Frequency from potentiometer)

Push button “RUN” on the panel, inverter starts up and running indicator is on.

Push the button again, inverter would stop.

8.2 Operation by external signal

Pn 04=2 (command from port "FWD/REV")

Pn 03=3 (frequency from port "5V")

8.3 Multi-segment speed

Pn 04=2(command from port "FWD/REV")

Pn 03=7(frequency from multi-segment 0-7)

8.4 Point move by panel

Command (Pn 04) must come from panel (=1). Frequency (Pn 03) must be specified by button (=2). After inverter stops, push button “←” to clockwise point move and “→” to anticlockwise point move.

8.5 Point move by external signal

Command ( Pn 04 ) must come from port "FWD/REV" (=2 ) .

Frequency (Pn 03) must come from external digital port (=6). After inverter stops, connect "D0" and "JOG" to "GND" to point move

clockwise, connect "D1" and "JOG" to "GND" to point move anticlockwise.

9.2 Other unexpected fault

1. Inverter is in normal condition but without any output
2. Internal fuse fail
3. Internal drive module fail

10. Maintenance and Repair

Due to the environment influence such as temperature, humidity, dust and vibration etc., and aging component, inverter may be fail at some time. So it needs periodic maintenance and repair.

Notice: please check following items before maintenance and repair.

Otherwise, it may cause electronic shock.

1. Power source is cut off.
2. Indicator on panel is OFF.
3. Maintenance is performed by professionals.

10.1 Daily maintenance and repair

Inverter must be install in the standard environment according this manual. There may be some unexpected situation during runtime. Please do daily maintenance work according following table. Keep good runtime environment, log daily data and detect fault cause in an early time. It can extend the life of inverter.

Item	Check			Criterion
	Content	Period	Method
environment	(1) temperature, humidity(2) dust, water(3) corrosive gas	anytime	(1) thermometer, hygrometer(2) watch(3) smell	(1) temperature range 10°C ~+40°C(2) any mark of water(3) odor

motor	(1) heat(2) noise	anytime	(1) touch(2) sound	(1) abnormal heating(2) abnormal sound

10.2 Periodic maintenance

Inverter needs periodic maintenance every 1 or 3 month which depends on the runtime environment.

Notice: Machine maintenance or components replace must be performed by professionals. If any metal objects such screws or washer are left inside the machine, it would cause fatal damage to the inverter!

Check itmes:

1. Whether the control port screws are loose or not;
2. Whether the main loop port are loose or not. Or is there any sign overheated in the line of main loop;
3. Is there any trauma in power and control cable. Especially, check the robber skin in the contact with other metal;
4. Is the insulation bandage of power cable loose;
5. Use vacuum cleaner to clean dust on board and ventilation channel
6. If the motor needs examination, please disconnect the motor wire from inverter's U,V,W port. Otherwise, it may cause fatal damage to inverter.

Notice: Inverter has already passed the pressure test. Any improper test may cause fatal damage to inverter!

10.3 Replace the wearing parts

The wearing parts contain cooling fan and filter electrolytic capacitor whose lifetime depends on environment and load. When the temperature is 25^ C, the lifetime of cooling fan is 20\~40Kh and that of capacitor is 30\~50Kh. User can decide when to replace these components.

1. Cooling fan

Cause of damage: wear bearing, aging fan, heavy dust environment. Criterion: rip in fans, abnormal vibration during runtime.

2. filter electrolytic capacitor

Cause of damage: high environment temperature, frequently load change, long-time fully load.

Criterion: liquid leak, wrong position of safety valve, capacity measurement.

10.4 Store of inverter

Precautions for storing inverter:

1. It cannot be stored in high temperature, moist, dusty, metal dust, corrosive gas places.
2. It will speed up the capacitor aging during long-time store. Make sure that turn on inverter once every year. The operation time cannot below 8 hours. And the input voltage increases slowly to the rating value.

10.5 Warranty

Range: inverter itself;

If any following situation happens, Isacon will provide warranty:

Any fault or damage happens during the standard use in 18 months.

Beyond 18 months, Isacon will charge for the maintenance and repair; If any following situation happens, even in 18 months, Isacon still can charge for maintenance and repair:

A. damage caused by wrong operation;
B. damage caused by voltage abnormal and nature disaster such fire and floods etc.;
C. apply inverter in non-standard user case.

Costs can be counted as listed on contract or actual cost.
