2. TROUBLE SHOOTING 2.1 Inverter trip contents, remedy, advice Trip Digital operator display contents It’s one of INV failure by locked motor, fast ACC/DEC because big current will be flown. By over current detection, INV will shut the output by the hardware. This detection will be done by AC CT.
Trip contents Instant power detection failure Over heat detection Gate array(INV domestic problem) Input phase detection failure IGBT over current detection (equivalent as power module) Thermister(customer’s selection) If Instant power failure 15ms or more happened, INV will shut the output. If the instant power failure is longer than preset allowable time or affordable control supply voltage time, INV will work as normal power off.
2.2 Option error 2.2.1 Feed-back board (SJ-FB) Trip Contents Encorder wire cut ü Wire break and/or loose connection of the encoder signal. ü Encoder failure or used the encoder which is not line driver output. ü Used encoder without Z phase signal. Over speed Detect when the motor rotation exceeds (Maximum frequency) × (over speed detection level (P026)) Positioning error Detects when the deviation between actual position and position command exceeds 1,000,000 pulses.
2.3 Check of the trip monitor contents (1) Trip cause / Display explanation 1 Trip cause. Inverter status at tripping Refer to 4.4.1 : While reset (2) Output frequency at trip (Hz) : While standstill 1 : While deceleration : While constant speed (3) Output current at trip (A) 1 : While acceleration : Running command ON while 0Hz command.
2.4 Check of the warning monitor contents Warning message is come out when there is any contradiction. Program lamp “PRG” is turned ON while warning (until the data are corrected).
2.5 Return to an initialization setup (Factory-shipment state) The rewritten setting value is initialized and it can return to the state at the time of factory shipments. The career of a trip is clearable. The contents of initialization are as follows. RUN time and power supply ON time are unclearable. Item FNC mode Data 00 b084 01 Initialization selection Contents Only a trip career is cleared. Only initialization of setting value is carried out.

3.3 A setup of an inverter The logic board of 55 or less kW’s is common by each capacity (0.4-55kW) and the voltage class (200/400V). Please check that name plate of logic is after SJ300P-L K. However, it is necessary to unite with an inverter main part and to set up a logic board. 3.3.1 Setting procedure (1) Preparation before switching on a power supply (1)-1 Please connect a digital operator. (2) Please carry out a power supply injection.
(2) A setup of output capacity is checked. (The check method) Please display H003, push FUNC key and check that it is ***. * Please check having become as shown in H003 of Table 1 and Table 2 about a display of the portion of ***. (3) Model selection of Sj300 /L300P is checked. (The check method) Please display H-- and check that the displays when pushing FUNC key once are SJ300:H001 and L300P:H003. Table1.

5. Maintenance and Inspection 5.1 Maintenance and Inspection 5.1.1 Daily inspection Main check points to be done while operation are as follows. (1) Whether the motor rotates as expected. (2) Whether the installation condition have no problem. (3) Whether there is no problem in cooling. (4) Whether there is any abnormal vibration and noise. (5) Whether there is any abnormal temperature rising and change in color. (6) Whether there is any abnormal smell.
5.2 Daily and annual maintenance Overall Item Ambient Environment Devices overall Power supply voltage Overall Contents Interval D A Check ambient temperature, humidity, dust, corrosive gas, oil X mist, etc. Check for abnormal vibrations X and noise. Check voltage between X input lines Megger check (Power terminal - Earth) Check installation for looseness.
5.3 Megger test Disconnect all the wiring in case of megger test on external circuit, so that no test voltage is supplied to the inverter. Use tester (high resistance range) for the test of control circuit. Do not use megger nor buzzer. Megger test should be done only on the power (mains) portions. Do not perform megger test on control circuits. (Use DC500V megger in case of megger test.
5.5 How to check inverter & converter portion Inverter and converter module can be checked by using a tester. (Preparation) (1)Disconnect all the connected wires and devices to the power terminals (R, S, T, U, V, W, P and RB). (2)Tester is to be set as 1ohm range. (How to check) Check the ON condition of each point shown below. (note 1) Be sure to discharge DC bus voltage beforehand, which should be checked by DC bus voltage. (note 2) Normally, the resistance shows ∞ in case of OFF mode.
5.6 Parts replacement Inverter is consists from many electrical components. And inverter cannot work properly unless all of them works normal. Electrical components in following table are the components which may degrade according to the usage period. HITACHI recommend to replace those electrical Parts name Recommended period for replacement Cooling fan 2 ~ 3 years DC bus capacitors 5 years Electrolytic capacitors 5 years on PCB Relays - components periodically to avoid any expected failure caused by them.
