 Parameters to be overwritten with the tuning result data after tuning of PM motor
Pr.
90 (458) Motor constant (R1)
92 (460) Motor constant (L1)/d-axis inductance (Ld)
93 (461) Motor constant (L2)/q-axis inductance (Lq)
711 (739) Motor Ld decay ratio
712 (740) Motor Lq decay ratio
859 (860) Torque current/Rated PM motor current
96 (463) Auto tuning setting/status
373 Encoder position tuning setting/status
1105 Encoder magnetic pole position offset
: Tuned, ―: Not tuned
NOTE
• If the offline auto tuning is started before the encoder position tuning for a PM motor is finished (Pr.1105 = "9999"), the
protective function (E.MP) is activated.
