Chapter 6 - Parameter Description [FU2]

FU2-40	LCD display	Description
0	No	Auto-tuning disabled
1	All	Auto-tuning all
		parameters
		Stator resistance (Rs) and
2	Rs + Lsigma	Leakage inductance
		(Lsigma) Auto-tuning
3	Enc Test	PG status check
4	Tr	Rotor constant(Tr)
		calculation

➨Note 1 : Ls and Noload-Curr are only valid during Motor Rotation mode.

➨Note 2 : The motor constants values change with temperature change, so auto tuning is to be conducted after the temperature of the motor is stabilized.

➨Note 3 : The auto-tuning result could be different unless CMC motor is used.

➨Note 4 : The actual motor parameters (Rs, Rr, Lsigma, Tr) can be used or set by user.

SL P-gain is the proportional gain of speed controller. If this value is set high, you can get fast speed response characteristic. However, if this value is set too high, the steady state characteristics may become unstable.
