Check that none of the internal parts have been damaged or have fallen off. D. Check that none of the connectors have been damaged or have fallen off. E. Check that there is no loosening of the terminals or screws of each of the parts. 2. Installation and Storage A. Storage: If the equipment is not to be installed immediately, it should be stored in a clean and dry location at ambient temperatures from 2 to 55. The surrounding air must be free of corrosive contaminants. B. Installation place: Places where the peripheral temperature is from -1 to 4, and where the relative humidity is 9% or less. Avoid installing at places where there is dust, iron particles, corrosive gas, water spray, direct sunlight or too much vibration. And places where has good ventilation. 1cm min. 1cm min. 1cm min. 1cm min. 3. Application notes A. Concerning the inverter unit: (1) Do not fit capacitors to the output side of the inverter in order to improve the power ratio. (2) In case of fitting MC between inverter and motor to control motor operation, then the capacity of inverter must be 6 times the capacity

4 of motor. (3) Run a motor that is within the capacity of the inverter unit, light load current and no-load current will cause the motor to develop ripple current. (4) This unit is provided with a current limiting function. The starting torque is assumed to be from 8% to 12%. B. Concerning the AC motor (1) When general-purpose motors are operated at low speeds, there is a reduced cooling effect, please apply the special purpose motor. (2) Operation at frequencies exceeding 6 Hz requires caution as there is the danger of the mechanical strength failure of the motor. (3) When motors with brakes are being operated, the power for the brake and inverter should be taken from the same power supply and the brake operation must be in phase when the unit is started and stopped. 4.

32 8. Troubleshooting Description of trouble Possible cause Solution The motor does not run at all OCPA is indicated as soon as the motor is started. (Overcurrent protect operation during acceleration.) OCPd is indicated as the motor is decelerating. (Overcurrent protect operation during deceleration). OC or OCS is indicated during operation. (Overcurrent) 1. Wiring error Refer to the wiring diagram 1. Check the power input wiring 2. Is there a voltage for U.V.W output 2. Wrong settings at operator panel The function code No.4 is as follows : Panel key operation 1: External signals 3. Inverter displays fault indication Refer to Protect Function 4. Motor cannot start due Exchange a higher capacity one to overload 5. Motor breaks down Repair motor 6. Inverter breaks down Please contact us 1. Motor wiring error Refer to the wiring diagram 2. Overload Reduce the load or increase inverter capacity 3. Is V/F slope appropriate Check Code 5 V/F slope is appropriate with motor specification 4. Is start torque appropriate Adjust Code 7 torque boost to over come steady friction but not over current trip. 5. Is the acceleration time too short when compared to load GD 2 Lengthen acceleration time by apply Code 8 and Code 1 or increase inverter capacity 6. The inverter is starting Refers to Code 28, change the value from during motor free-run to 1 1. Deceleration time too Apply Code 9 and Code 11 to lengthen short, unable to be deceleration time or increase inverter loaded capacity 1. Short circuit on U.V.W Exclude short circuit or grounding or grounding for motor 2. Instantaneously Reduce load or increase inverter capacity mechanical load on motor 3. Motor breaks down Repair motor

33 4. Inverter breaks down Please contact us OU is displayed 1. Is power voltage with Improve power voltage condition during inverter operation 2. the specification Braking resistor not Apply braking resistor, increase braking applied ratio 3. Deceleration time too short, unable to be Apply Code 9 and Code 11 to lengthen deceleration time loaded LU is displayed 1. Is power voltage with Improve power voltage condition during inverter operation 2. the specification Instantaneous power Check the capacity of the power facilities voltage failure 3. Power dropped and Check the capacity of the power facilities the protector function has operated OL is displayed 1. Overload Reduce load or increase inverter capacity during inverter 2. Is inverter overcurrent Apply Code 6 to re-set motor rated operation limiter appropriate current OH is displayed during inverter operation Check if the cooling fan is still working Is ambient temperature too hot Change cooling fan and clean dirt Improve ambient temperature condition No any indication, the 1. Power failure Check the capacity of the power facilities output frequency displayed 2. Is there loosen part on Check external control terminal external control terminal

34 9. Maintenance and Inspection Maintenance and inspection must be taken under power off. Cautions on maintenance and inspection: (1) Capacitor is charged at high voltage for a while after turning off the power. (Accordingly, start the inspection work at least 5 minutes after turning off the power) (2) Do the work with operator. Inspection items: (1) Please check the following items A. Motor runs as expected. B. Avoid installing on circumstances like acid, alkaloid. C. No trouble is recognized in the cooling system and irregular vibration or noise. D. No parts is overheated or burned. (2) Periodic inspection Interval Inspection item Every 6 months 1. Terminal plates and mounting bolts. 2. Corrosion and breaks in the terminal clips for the wiring. 3. Condition for the connector fixing. Once a year 1. Use clean, dry air to remove dust buildup from the guards, the stack and the cooling fan. 2. Check for parts burns or damage and make any exchanges necessary.
