Tips: Difference between VSD, VFD, ASD, AFD

The most correct term - according to IEEE and IEC - is ASD (Adjustable Speed Drive). This refers to the electronic equipment used to regulate the operating speed of the motor and driven equipment by controlling the frequency and voltage applied to the motor.
NOTE that other terms in common use include (but are not limited to): VSD (Variable Speed Drive), AFD (Adjustable Frequency Drive), and VFD (Variable Frequency Drive), they are referring to the same motor drives, just different names.
There is no difference between a VSD and VFD in terms of what it is designed to do. There MAY be differences based on specific internal components/construction and how it achieves that goal.

Do I need a bigger VFD?

The VFD does not seem capable of running the motor & pump. I tried increasing the acceleration time to 10 seconds and increased the torque percent to 20%, but it doesn't help. Please advise do I need a bigger VFD?
