10.7 If the Inverter is Running on Single-Phase Power [ 1 ] The AC fan(s) does not work. (230 V series with 60 HP or above or 460 V series with 125 HP or above) Possible Causes The power supply is connected to the main circuit power input terminal L2. Suggested Measures Connect the power supply to L1 and L3. [ 2 ] _ _ _ _ (under bar) appears Possible Causes The power supply is connected to the main circuit power input terminal L2 and the main power down detection is activated. Suggested Measures Connect the power supply to L1 and L3. [ 3 ] The motor does not run as expected. Possible Causes Large voltage ripple inside the inverter due to single-phase power Suggested Measures When the inverter runs on single-phase power, the voltage ripple becomes larger than that on three-phase power so that an operation error span becomes wider, causing lower performance than expected. To improve the accuracy in operation, use the inverter on three-phase power. [ 4 ] Charger circuit fault (230 V series with 60 HP or above or 460 V series with 125 HP or above) Possible Causes The power supply is connected to the main circuit power input terminal L2. Suggested Measures Connect the power supply to L1 and L3. [ 5 ] Input phase loss Possible Causes The input phase loss protection is activated. Suggested Measures Disable the input phase loss protection by switching Bit 1 of H98 to "0." When switching from the factory default of H98, modify the H98 data from 82 to 81 in decimal. [ 6 ] Heat sink overheat, Inverter internal overheat, or Inverter overload Possible Causes The inverter was running with load exceeding the single-phase rating. Suggested Measures To run the inverter on single-phase power, it is necessary to derate the output to the lower level than that on three-phase power. Review the load conditions to run the inverter within the single-phase rating, or increase the inverter capacity. 10-27

(*3) Output voltage cannot exceed the power supply voltage. At single-phase input use, the output voltage may be lower than three-phase input. (*4) Voltage unbalance [%] = (Max. voltage [V] - Min. voltage [V])/Three-phase average voltage [V]×67(See IEC61800-3.) If this value is 2 to 3%, use an optional AC reactor (ACR). (*5) Required when a DC reactor (DCR) is used. (*6) Without external braking resistor condition. Average braking torque for the motor running alone. (It varies with the efficiency of the motor.) (*7) For Inverters of 100HP or above , the DC reactor is provided as separate standard component. Be sure to connect it to those inverters. 11-1
