User Manual EM303B General Purpose Inverter F1-08 ～ F1-13 are motor parameters, please autotune motor parameter to obtain the above parameters. (F1-09 can be autotuned, but cannot be edited through keypad or communication.) Before autotuning motor parameter, inverter will set the nameplate parameters (set by F1-00 ～ F1-07) as the standard motor parameters automatically. The T Equivalent Model of motor is as shown in Figure7-7.
R1 L1-Lm R2 L2-Lm I1 I2 U1 I0 Lm (1-s)/s*R2 Figure 7-7 T Equivalent Model of Induction Motor R1, L1, R2, L2, Lm, and I0 in Figure 7-7 refers to stator resistance, stator inductance, rotor resistance, rotor inductance, stator and rotor mutual inductance, and idling excitation current respectively. F1-15=0 No autotuning F1-15=1 Motor remains motionless in the process of autotuning parameters F1-07 and F1-10 ～ F1-14. F1-15=2 Motor is rotating in the process of autotuning parameters F1-07 and F1-10 ～ F1-14. After parameters autotuning completed, F1-15=0 will be set automatically.
When slip compensation is enabled, autotune motor parameter first, so that the motor will obtain the optimum operation performance. Parameter autotuning is only enabled when F0-04=0. EM303B supports ModBus protocol, RTU format, and single-master and multi-slave communication network with RS485 bus. 93 Stator& Rotor Leakage Inductance Ls 0.1~3000.0 mH XXXX 〇 F1-12 Stator& Rotor Mutual Inductance Lm 0.1~3000.0 mH XXXX 〇 F1-13 No. Function Range Unit Default Type Autotuning Parameters 0: No autotuning 1: Stationary autotuning (R,R,Ls,Lm,I ) 1 2 0 2: Rotational autotuning (R,R,Ls,Lm,I ) 1 2 0 0 〇 F1-15 No. Function Range Unit Default Type Inverter Address 1～247, 0:
