Troubleshooting 9.1.1 Fault Detection Protective and Diagnostic Functions 9.1.1 Fault Detection When the Inverter detects a fault, the fault code is displayed on the Digital Operator, the fault contact output operates, and the Inverter output is shut OFF causing the motor to coast to a stop. (The stopping method can be selected for some faults, and the selected stopping method will be used with these faults.) When a fault has occurred, refer to the following table to identify and correct the cause of the fault.

9.2 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. If the contents of the fault are displayed, refer to 9.1 Protective and Diagnostic Functions.

Maintenance and Inspection WARNING D Do not touch the Inverter terminals. Some of the terminals carry high voltages and are extremely dangerous. Doing so can result in electric shock. D Always have the protective cover in place when power is being supplied to the Inverter. When attaching the cover, always turn OFF power to the Inverter through the MCCB.

Appendix This chapter provides precautions for the Inverter, motor, and peripheral devices and also provides lists of constants. 12 - 2 12.1 Inverter Application Precautions ..12 - 2 12.1.1 Selection .
Page 271
Appendix 12.1.1 Selection 12.1 Inverter Application Precautions 12.1.1 Selection Installing Reactors A large peak current will flow in the power input circuit when the Inverter is connected to a large-capacity power transformer (600 kVA or higher) or when switching a phase capacitor. Excessive peak current can de- stroy the convertor section.
Page 272
12.1 Inverter Application Precautions 12.1.3 Settings Upper Limits The Digital Operator can be used to set high-speed operation up to a maximum of 400 Hz. Incorrect settings can be dangerous. Use the maximum frequency setting functions to set upper limits. (The maximum output frequency is factory-set to 60 Hz.) DC Injection Braking The motor can overheat if the DC injection braking voltage or braking time is set to a large value.
Page 273
Frequency (Hz) If the input voltage is high (440 V or higher) or the wiring distance is long, the motor insulation voltage must be considered. Contact your Yaskawa representative for details. High-speed Operation When using the motor at a high speed (60 Hz or more), problems may arise in dynamic balance and bearing durability.
Page 274
12.2 Motor Application Precautions 12.2.2 Using the Inverter for Special Motors Pole-changing Motor The rated input current of pole-changing motors differs from that of standard motors. Select, therefore, an appropriate Inverter according to the maximum input current of the motor to be used. Before changing the number of poles, always make sure that the motor has stopped.
Page 275
Select the MCCB according to the Inverter’s power supply power factor (which changes with the supply volt- age, output frequency, and load) . Contact your Yaskawa representative for selection standards. Operating characteristics of completely magnetic MCCBs change with high-frequency currents. Select a model with a large capacity.
Page 276
12.3 Peripheral Device Application Precautions Wire Sizes and Distances Motor torque will be reduced by voltage drop along the cable if the distance between the Inverter and the motor is too long. This is particularly noticeable for low-frequency outputs. Use wires of sufficient size. Always use the optional extension cables when operating the Digital Operator separated from the Inverter.
