EM500 Open-Loop Vector Control Inverter User Manual 71 Inverter frequency and fault output. For hoisting equipment, the following protection settings shall be invalid: Current limit protection and overvoltage stall protection. Before running for the first time, please conduct motor parameter autotuning, in order to obtain the correct electrical parameters of the controlled motor. If motor load cannot be removed, select motor stationary autotuning (F01.34=1/11); afterwards, press ENTER of keypad first and then press RUN . If motor is still running, do not conduct motor parameter autotuning operation.
Motor Parameter Autotuning Correctly set rotational direction, forward/reverse control, acceleration/deceleration time, driving mode, start/stop mode, speed torque control mode and other parameters according to the working conditions of the driving system. General Parameter Set function parameters including the V/F curve, stator voltage drop compensation and slip compensation, according to the load demands. Operation Control V/F Parameter Control Setting Vector Set regulator parameters according to the load. Control When motor is idling, start inverter at a low speed or allow it for jog running, and check and confirm the running status of driving system: Motor:
Motor runs stably and rotates normally and correctly; the acceleration/deceleration process is normal, free of abnormal vibration, noise and foreign odor. Inverter: Operation panel displays data normally, fan rotates normally and relay acts normally, free from vibration and foreign odor. In case of abnormal condition, immediately stop it and cut the power for checking. Idling Trial Operation Check On-Load Trial Conduct on-load trial operation check only after inverter has passed no-load operation check satisfactorily, . Operation Check
