Tips: Considerations of selecting a VFD
When you use a Variable Frequency Drive (VFD), you need not worry about initial inrush, as its starting current will be only 100% of full load current. But this is not the main criteria for VFD selection. You have to find out the nature of load ie whether it is a constant load torque or variable load torque.
Nominal current demand will tell you the size required for the VFD selection but also you need to look at the application requirement for features. Proper torque control considerations, proper protection from the applications environment and harmonics too. Reaching out to a trained rep from a distributor of quality VFDs is best.
As those astute applications, there is not enough information.
1) What is the load? (CT or VT)
2) What is the voltage of the motor?
3) What is the duty cycle (how many starts/ stops per hour)
4) Are there any unusual operating conditions?
With this information, most VFD manufacturers should begin to address your application. REMEMBER, more info is always better that too little. Also you can follow this selection guide.
