Auto-Tuning Automatic motor parameter estimation in two stages

Stage 1

Motor does not spin

Stator resistance and Leakage inductance are estimated

Current Loop Gains are calculated and saved

Stage 2

Motor spins to 30% speed

Requires that the load be decoupled from the motor

Motor No-load Current and Inertia are estimated

Flux Loop and Speed Loop Gains are calculated and saved



Dual-Frequency Braking

New strategy for control of Harmony with Bypassed cells

Zero hardware braking solution for VFDs

Dynamic braking using high frequency ac injection instead of d

c injection

Dissipates kinetic energy in the motor instead of the drive

Achieves 12% negative power (best case) without exceeding r

ated current
