Procedure
Group:
Auto Tune Description: Parameter 546 is used to allow the user a means of configuring the auto tune procedure execution.
Structure of the auto tune selections:
Bits 3-0:
Bit 0 = Auto Save- If selected, the calculated auto tune parameters are saved after completion of the auto
tune cycle
Bit 1 = Calculate Gains - If selected, the loop gains will be calculated.
Bit 2 = Inertia - If selected, the auto tune procedure performs an inertial tune.
Bit 3 = Analog Offset - If selected, the auto tune procedure calculates the auto zero speed A/D offset,
Parameter 693, “AnaInput 1 Offse”.
