Chapter 5 Troubleshooting| 5.13 Electromagnetic/Induction Noise Many sources of noise surround AC motor drives and penetrate it by radiation or conduction. It may cause malfunctioning of the control circuits and even damage the AC motor drive. Of course, there are solutions to increase the noise tolerance of an AC motor drive. But this has its limits. Therefore, solving it from the outside as follows will be the best. 1. 2. Add surge suppressor on the relays and contacts to suppress switching surges.
Chapter 5 Troubleshooting| 4. Store within a relative humidity range of 0% to 90% and non-condensing environment. Use an air conditioner and/or exsiccator. 5.15 Affecting Other Machines An AC motor drive may affect the operation of other machines due to many reasons. Some solutions are: High Harmonics at Power Side High harmonics at power side during running can be improved by: 1. Separate the power system: use a transformer for AC motor drive. 2.
Chapter 6 Fault Code Information and Maintenance 6.1 Fault Code Information The AC motor drive has a comprehensive fault diagnostic system that includes several different alarms and fault messages. Once a fault is detected, the corresponding protective functions will be activated. The following faults are displayed as shown on the AC motor drive digital keypad display. The five most recent faults can be read from the digital keypad or communication.

Chapter 6 Fault Code Information and Maintenance| 6.1.2 Reset There are three methods to reset the AC motor drive after solving the fault: 1. 2. Press key on keypad. Set external terminal to “RESET” (set one of Pr.04.05~Pr.04.08 to 05) and then set to be ON. 3. Send “RESET” command by communication. NOTE Make sure that RUN command or signal is OFF before executing RESET to prevent damage or personal injury due to immediate operation. 6.

Appendix C How to Select the Right AC Motor Drive The choice of the right AC motor drive for the application is very important and has great influence on its lifetime. If the capacity of AC motor drive is too large, it cannot offer complete protection to the motor and motor maybe damaged. If the capacity of AC motor drive is too small, it cannot offer the required performance and the AC motor drive maybe damaged due to overloading.
Appendix C How to Select the Right AC Motor Drive| C.1 Capacity Formulas 1. When one AC motor drive operates one motor The starting capacity should be less than 1.5x rated capacity of AC motor drive The starting capacity= ⎛ k×N GD 2 N ⎞ ⎜ TL + × ⎟ ≤ 1.5 × the _ capacity _ of _ AC _ motor _ drive ( kVA) 973 × η × cos ϕ ⎜⎝ 375 t A ⎟⎠ 2. When one AC motor drive operates more than one motor 2.

Appendix C How to Select the Right AC Motor Drive| C.2 General Precaution Selection Note 1. When the AC Motor Drive is connected directly to a large-capacity power transformer (600kVA or above) or when a phase lead capacitor is switched, excess peak currents may occur in the power input circuit and the converter section may be damaged. To avoid this, use an AC input reactor (optional) before AC Motor Drive mains input to reduce the current and improve the input power efficiency. 2.

C.3 How to Choose a Suitable Motor Standard motor When using the AC Motor Drive to operate a standard 3-phase induction motor, take the following precautions: 1. 2. The energy loss is greater than for an inverter duty motor.
Appendix C How to Select the Right AC Motor Drive| 7. Motor torque characteristics vary when an AC Motor Drive instead of commercial power supply drives the motor. Check the load torque characteristics of the machine to be connected. 8. Because of the high carrier frequency PWM control of the VFD series, pay attention to the following motor vibration problems: Resonant mechanical vibration: anti-vibration (damping) rubbers should be used to mount equipment that runs at varying speed.
Appendix C How to Select the Right AC Motor Drive| motor drive operates more than one motor, please pay attention to starting and changing the motor. Power Transmission Mechanism Pay attention to reduced lubrication when operating gear reduction motors, gearboxes, belts and chains, etc. over longer periods at low speeds. At high speeds of 50/60Hz and above, lifetime reducing noises and vibrations may occur.
