Introduction Inverter Specifications Label The Hitachi SJ200 inverters have product labels located on the right side of the housing, as pictured below. Be sure to verify that the specifications on the labels match your power source, motor, and application safety requirements.
2–2 Orientation to Inverter Features Orientation to Inverter Features Unpacking and Inspection Please take a few moments to unpack your new SJ200 inverter and perform these steps: 1. Look for any damage that may have occurred during shipping. 2. Verify the contents of the box include: a.
2–3 SJ200 Inverter Inverter Keypad Keypad Removal - The SJ200 has a removable keypad. To remove the keypad, locate the retention latch as shown to the right. Press downward on the latch, while gently pulling toward you. The keypad will tilt forward, as two retaining tabs at the bottom edge of the keypad also hold it in place.
2–4 Orientation to Inverter Features Front Housing Cover Housing Cover Removal - The front housing cover is held in place by two pairs of tabs. Since these are hidden from view, it is good to become familiar with their locations before attempting to remove the cover.
Removing the Cover (Slide type) 1. Press downward on the cover at the two areas indicated to release the retaining tabs. 2. Slide the cover forward and away from the keypad until the top edge of the cover reaches the notch in the inverter chassis.
2–5 SJ200 Inverter Logic Connector Locations - After removing the front housing cover, take a moment to become familiar with the connectors, as shown below. Relay output Logic inputs contacts Analog input/ output and logic outputs Logic Connector Removal/Replacement - The two 8-position main logic connectors are removable from the circuit board to make testing or service more convenient.
2–6 Orientation to Inverter Features Power Wiring Access - First, ensure no power source of any kind is connected to the inverter. If power has been connected, wait five minutes after powerdown and verify the Power LED is OFF to proceed. After removing the front housing cover, the housing partition that covers the power wiring exit will be able to slide upward as shown to the right.
B–4 Connecting the Inverter to ModBus OPE / 485 DIP Switch - The difference between OPE-S and OPE-Smini is the short-circuit inside the connector. If you set 485-side OPE-S,SRW says "----"(communication error) But OPE-Smini works properly.

6–2 Troubleshooting Troubleshooting Safety Messages Please read the following safety messages before troubleshooting or performing mainte- nance on the inverter and motor system. WARNING: Wait at least five (5) minutes after turning OFF the input power supply before performing maintenance or an inspection. Otherwise, there is the danger of electric shock.
6–3 SJ200 Inverter Troubleshooting Tips The table below lists typical symptoms and the corresponding solution(s). Symptom/condition Probable Cause Solution • • Is the frequency command source Make sure the parameter A001 parameter setting correct? setting A001 is correct. • • Is the Run command source A002 Make sure the parameter parameter setting correct?
6–4 Troubleshooting Symptom/condition Probable Cause Solution • • If using the analog input, is the Check the wiring. current or voltage at [O] or [OI]? • Check the potentiometer or signal generating device. • • Is the load too heavy? Reduce the load.

6–6 Monitoring Trip Events, History, & Conditions Error Name Cause(s) Code E 1 1 CPU error A malfunction in the built-in CPU has occurred, so the inverter trips and turns OFF its output to the E 2 2 motor. E 1 2 External trip A signal on an intelligent input terminal configured as EXT has occurred.
6–7 SJ200 Inverter Trip History and Inverter Status We recommend that you first find the cause of the fault before clearing it. When a fault occurs, the inverter stores important performance data at the moment of the fault. To access the data, use the monitor functions (Dxxx) and select D081 for details about the present fault (E ).
6–8 Restoring Factory Default Settings Restoring Factory Default Settings You can restore all inverter parameters to the original factory (default) settings for the intended country of use. After initializing the inverter, use the powerup test in Chapter 2 to get the motor running again. To initialize the inverter, follow the steps below. Action Display Func./Parameter...

Debug Mode If you set debug mode enable (C091 =01), the function below will be available. When debugging, you can use only standard OPE (cannot use SRW) Make sure of returning C091=00 after debugging. There are some monitor or function-code for testing and maintenance which is not released for users.
6–10 Maintenance and Inspection Megger Test The megger is a piece of test equipment that uses a high voltage to determine if an insulation degradation has occurred. For inverters, it is important that the power termi- nals be isolated from the Earth GND terminal via the proper amount of insulation. The circuit diagram below shows the inverter wiring for performing the megger test.

6–14 Maintenance and Inspection Inverter Output Voltage Measurement Techniques Taking voltage measurements around drives equipment requires the right equipment and a safe approach. You are working with high voltages and high-frequency switching waveforms that are not pure sinusoids. Digital voltmeters will not usually produce reliable readings for these waveforms.
6–15 SJ200 Inverter IGBT Test Method The following procedure will check the inverter transistors (IGBTs) and diodes: 1. Disconnect input power to terminals [R, S, and T] and motor terminals [U, V, and W]. 2. Disconnect any wires from terminals [+] and [RB] for regenerative braking. 3.
