User Manual of EM730 Series Inverter F00.24=0: invalid The carrier frequency is dependent on F00.23, but limited by the allowable maximum carrier frequency. It will not change during operation. F00.24=1: valid 1 The carrier frequency is affected by the inverter temperature and load based on the F00.23 setting. If the inverter temperature is too high or the load is too heavy, the carrier frequency will be limited. When the set carrier frequency F00.23 is greater than the limit, the carrier frequency of the inverter will be the limit during operation. F00.24=2: valid 2 The carrier frequency is auto-tuned on the basis of the F00.23 setting.
When the noise suppression function is enabled (F00.25=1), the motor noise can be suppressed to a certain extent. The EM730 series inverter supports time-sharing control of two motors. The motor parameters and control parameters can be set separately. The corresponding parameters of the motor 1 are in the F00 group, F01 group and F06 group, and those of the motor 2 are in the F14 group. The valid motor can be selected in conjunction with F00.28 and the input function “Motor 1/Motor 2 switching”, as detailed in Table 7-5.
