These parameters only apply when 0:65 [Pri MtrCtrl Mode] = Induction SV (1), Induct Econ (2), Induction FV (3), IPM FV (4), or SPM FV (5).
Current Regulator Gain Calculation
Closed loop current regulator gains are calculated as functions of bandwidth and damping:
VCL CReg IdKp = Ld*2*B
W
VCL CReg IqKp = Lq*2*B
W
VCL CReg IdKi = VCL CReg IqKi = 2*B
W
*Rs/Damping
For IM motors:
B
W
= 10:445 [VCL CReg BW]
Damping = 10:450 [VCL CReg Damping]
Rs = 10:511 [c IM Stator Res] or 10:512 [u IM Stator Res]
Ld = Lq = 10:514 [c IM Leakage L] or 10:515 [u IM Leakage L]
For IPM and SPM motors:
B
W
= 10:445 [VCL CReg BW]
Damping = 10:450 [VCL CReg Damping]
Rs = 10:619 [c PM Stator Res] or 10:620 [u PM Stator Res]
Ld and Lq are the active values calculated by interpolation of autotune Ld and Lq values based on motor current.
Open loop current regulator gains for IPM and SPM motors are calculated as functions of bandwidth and damping:
VCL CReg IdKp = 2*B
W
*Ld100
VCL CReg IqKp = 2*B
W
*Lq75
VCL CReg IdKi = VCL CReg IqKi = 2*B
W
*Rs/Damping
