• Inertia
Inertia Tuning adjusts parameters controlling the Feed Forward and the KEB Ride-Thru
functions (L2-29 = 1 or H1-††=7A/7B).
• ASR Gain
ASR Gain Auto-Tuning performs the same operation as Inertia Tuning, but also adjusts the
ASR gain according to the response to the test signal.
• Back EMF
When the back EMF constant of motor dose not find, run the this tuning function. Drive
automatically calculates by rotating the motor and sets the back EMF constant.
Back EMF Constant Tuning is necessary to drive the motor, please run either of following
the tuning function to set the motor parameters.
－ PM Stationary Auto-Tuning or PM Stationary Auto-Tuning for Stator Resistance
－ Parameter Calculations function
• HF Injection
High frequency injection parameter tuning.
The high frequency injection parameter calculates and sets from the PM motor parameter.
• Tune-No Rotate 3
The same as Tune-No Rotate 1. Perform this type of Auto-Tuning on a second motor if
used (motor 2).
