Define V/f characteristic shape

Various characteristic shapes are available which are described in detail in the following subchapters.

Parameter

Address	Name / setting range / [default setting]		Information
0x2B00 (P302.00)	V/f characteristic shape (V/f charac.shape) – Setting can only be changed if the inverter is disabled.		Selection of the V/f characteristic shape for the adaptation to different load profiles.
	0	Linear	Linear characteristic for drives with constant load torque over the speed. Linear V/f characteristic
	1	Quadratic	Square-law characteristic for drives with a square-law load torque over the speed. – Square-law V/f characteristics are preferably used for centrifugal pumps and fan drives. – Please always check whether the corresponding application is suitable for operation with a square-law V/f characteristic! – If your pump drive or fan drive is not suitable for operation with a square-law V/f characteristic, use the linear V/f characteristic instead. Square-law V/f characteristic
	2	Multipoint	Multipoint characteristic for the purpose of adaptation to specific load profiles. Multipoint V/f characteristic Linear characteristic with additional characteristic point for adaptation to applications with special torque characteristics. Multipoint V/f characteristic
	3	Eco	Linear characteristic with energy optimisation in the partial load operational range. Energy-saving V/f characteristic (VFC-Eco)
	4	Adaptive	User-definable characteristic - adaptive curve. User-definable V/f characteristic Freely definable characteristic curve with 11 parameterizable grid points (voltage/frequency values). User-definable V/f characteristic
