When an operation error has occurred, refer to the following table to identify and correct the cause of the errors.

Page 193: Troubleshooting
Troubleshooting Troubleshooting Due to constant setting errors, faulty wiring, and so on, the Inverter and motor may not operate as expected when the system is started up. If that should occur, use this section as a reference and apply the appropriate measures.
Page 194: If The Motor Does Not Operate
If the Motor Does Not Operate Use the following information if the motor does not operate. The motor does not operate when the RUN Key on the Digital Operator is pressed. The following causes are possible. If the Inverter is not in drive mode and the DRIVE indicator on the Digital Operator (JVOP-160) does not light up, the Inverter will remain in ready status and will not start.
Page 195: If The Direction Of The Motor Rotation Is Reversed
Troubleshooting The operation method selection is wrong. If constant b1-02 (reference selection) is set to 0 (Digital Operator), the motor will not operate when an exter- nal operation signal is input. Set b1-02 to 3 (PLC) and try again. Similarly, the motor will also not operate if the LOCAL/REMOTE Key has been pressed to switch to Digital Operator operation.
Page 196: If The Motor Does Not Put Out Torque Or If Acceleration Is Slow
If the Motor Does Not Put Out Torque or If Acceleration is Slow Use the following information if the motor does not output torque or if acceleration is too slow. The torque limit has been reached. When a torque limit has been set in constants L7-01 to L7-04, no torque will be output beyond that limit. This can cause the torque to be insufficient, or the acceleration time to be too long.
Page 197: If There Is Low Speed Control Accuracy At High-Speed Rotation In Open-Loop Vector Control Method
Troubleshooting If There is Low Speed Control Accuracy at High-speed Rotation in Open- loop Vector Control Method The motor's rated voltage is high. The Inverter's maximum output voltage is determined by its input voltage. (For example, if 3300 VAC is input, then the maximum output voltage will be 3300 VAC.) If, as a result of vector control, the output voltage refer- ence value exceeds the Inverter output voltage maximum value, the speed control accuracy will decrease.
Page 198: If The Torque Generated For The Motor Is Insufficient (Insufficient Power)
Oscillation and hunting are occurring with open-loop vector control. The gain adjustment may be insufficient. Reset the gain to a more effective level by adjusting constants C4-02 (torque compensation time constant), n2-01 (Speed feedback detection control (AFR) gain), and C3-02 (Slip Compensation Primary Delay Time) in order.
Page 199: If Output Frequency Does Not Rise To Frequency Reference
Troubleshooting If Output Frequency Does Not Rise to Frequency Reference Use the following information if the output frequency does not rise to the frequency reference. The frequency reference is within the jump frequency range. When the jump frequency function is used, the output frequency does not change within the jump frequency range.

Page 201: Warranty Period
Maintenance and Inspection The FSDrive-MV1S series Inverter is configured with many parts, and these parts must be operating prop- erly in order to make full use of the Inverter functions. For this reason, it is essential to catch early signs of any malfunction and take prompt corrective action by periodically inspecting the Inverter.
Page 202: Periodic Inspection
Maintenance and Inspection Periodic Inspection Check the following items during periodic inspections. Turn off the power supply, make sure that all LEDs on the front cover of the cell control board are unlit, and then wait at least 5 minutes (10 minutes after turning off a medium voltage power supply) before starting inspection.

Page 204 Maintenance and Inspection The details of periodic inspections are described below. Megger Check (Measurement of Insulation Resistance) 1. Measure insulation resistance of the Inverter primary circuit. Use a 1000 V Megger insulation resistance tester. The measured insulation resistance must be 2 MΩ or more.
Page 205 Transformer Inspect the transformer as described below. 1. Check the external appearance 2. Retighten the bolts of transformer I/O terminals and primary voltage tap terminals 3. Measure the transformer secondary voltage. Turn on the control power supply and medium-voltage power supply, and measure the input voltages to the power cells as shown in Fig.

Maintenance and Inspection Air Filter If the air filter is clogged with dirt and dust, the cooling capacity of the Inverter will be degraded, resulting in abnormal temperature rise. Check the air filter for dirt and dust at each daily inspection, and periodically clean it with neutral detergent.
Page 207: Periodic Maintenance Of Parts
Periodic Maintenance of Parts In order to keep the FSDrive-MV1S series Inverter operating normally over a long period of time, we recom- mend replacing parts in accordance with their service life. The Inverter is configured with many parts, and these parts must be operating properly in order to make full use of the Inverter functions.
Page 208: Spare Parts
Maintenance and Inspection Spare Parts Considering the importance of the system in which the FSDrive-MV1S series Inverter is used, it is recom- mended that spare parts be prepared in advance for all possible measures for maintenance management. Table 8.4 lists the recommended spare parts. Confirm the following items and contact your Yaskawa representative when ordering the spare parts.

Page 214: Memory Backup Battery Replacement Procedure
Maintenance and Inspection Memory Backup Battery Replacement Procedure Replacement Period A battery for memory backup is provided in the controller. If the LED indicator lamp BAT ALM lights up, the battery voltage is low. Replace the battery. (We recom- mend replacing the battery every 5 years regardless of the indicator lamp status.) If the power supply is turned off while the BAT ALM is lit, the data and calendar settings stored in the mem- ory may be lost.
