Appendix B Accessories| Choose suitable motor cable and precautions Improper installation and choice of motor cable will affect the performance of EMI filter. Be sure to observe the following precautions when selecting motor cable. 1. Use the cable with shielding (double shielding is the best). 2. The shielding on both ends of the motor cable should be grounded with the minimum length and maximum contact area. 3. Remove any paint on metal saddle for good ground contact with the plate and shielding.
Appendix B Accessories| The length of motor cable When motor is driven by an AC motor drive of PWM type, the motor terminals will experience surge voltages easily due to components conversion of AC motor drive and cable capacitance. When the motor cable is very long (especially for the 460V series), surge voltages may reduce insulation quality. To prevent this situation, please follow the rules below: Use a motor with enhanced insulation.

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 CHow 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 CHow 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.
Appendix CHow to Select the Right AC Motor Drive| decelerate within a certain time with high load inertia that can’t be handled by the AC Motor Drive in the required time, either use an external brake resistor and/or brake unit, depending on the model, (to shorten deceleration time only) or increase the capacity for both the motor and the AC Motor Drive. C.
Appendix CHow 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.
Appendix CHow to Select the Right AC Motor Drive| the AC 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.
