Chapter 8Appendix C How to Select the Right AC Motor Drive

VFD-S Series

C.2 General Precautions

Selection Note

A.When the AC Motor Drive is connected directly to a large-capacity power transformer (600kVA or above) or when phase lead capacitors are switched, excess peak currents may occur in the power input circuit and the rectifier section might 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.

B.When a special motor is used or more than one motor is driven in parallel with a single AC Motor Drive, select the AC Motor Drive current ≥1.25x(Sum of the motor rated currents).

C.The starting and accel./decel. characteristics of a motor are limited by the rated current and the overload protection of the AC Motor Drive. Compared to running the motor D.O.L. (Direct On-Line), a lower starting torque output with AC Motor Drive can be expected. If higher starting torque is required (such as for elevators, mixers, tooling machines, etc.) use an AC Motor Drive of higher capacity or increase the capacities for both the motor and the AC Motor Drive.

D.When an error occurs on the drive, a protective circuit will be activated and the AC Motor Drive output is turned off and the motor will coast to stop. For an emergency stop, an external mechanical brake is needed to quickly stop the motor.

Parameter Settings Note

A.The AC Motor Drive can be driven at an output frequency up to 400Hz (less for some models). Setting errors may create a dangerous situation. For safety, the use of the upper limit frequency function is strongly recommended.

B.High DC brake operating voltages and long operation time (at low frequencies) may cause overheating of the motor. In that case, forced external motor cooling is recommended.

C.Motor accel./decel. time is determined by motor rated torque, load torque, and load inertia.
