EM500 Open-Loop Vector Control Inverter User Manual Conduct carrier frequency self-tuning based on the setting of F00.23. When noise suppression function is enabled (F00.25=1), a sine wave may be superposed on the basis of the set carrier wave (the frequency is set through F00.26 and the intensity is set through F00.27), which may suppress present motor noise to some extent. EM500 inverter supports the time interval based control of two motors, of which motor parameter and control parameter can be set separately. Motor 1 corresponds to parameters of F00, F01 and F06, and motor 2 corresponds to parameters of F14. F00.28 can be used to select present motor (see Table 7-3 for details).
In combination with the input function “30: Switch between Motor 1 and Motor 2”, Table 7-3 Motor Parameter Group Selection F00.29 is used to set a new password to enable the password protection function and avoid misoperation of the function codes of inverter. If the new password is 0, then the 170 No. Function Range Unit Default Type F00.25 Carrier Frequency Noise Suppression 0: Disabled 1: Enabled 0 〇 F00.26 Noise Suppression Tone 20 - 200 Hz 40 ● F00.27 Noise Suppression Intensity 10 - 150 Hz 100 ● No. Function Range Unit Default Type F00.28 Motor Parameter Group 0: Motor 1 Parameter 1: Motor 2 Parameter 0 〇 F00.28: Motor 30:
