User Manual of EM760 High-Performance Inverter F13.08=5: High-frequency pulse input (X7) The upper frequency limit in torque control is HDI (percentage) * F13.09. See 6.5.3 for the details when X7 serves as the high-speed pulse input. 100.00% is the percentage relative to the set value ofF13.09 (upper frequency limit for torque control). F13.08=6: communication percentage setting ● If the master-slave communication (F10.05=1) is enabled and the inverter works as the slave (F10.06=0), the upper frequency limit is “700FH (master-slave communication setting) * F10.08 (slave receiving proportional coefficient) * F00.18 (upper frequency limit)”, and the 700FH data range is -100.00% to 100.00%.
● For general communication (F10.05=0): the upper frequency limit is “700BH (communication percentage setting of the upper frequency limit of torque control) * F13.09 (upper frequency limit of torque control)”. The data range of 700BH is 0.00% - 200.00%. F13.08= 7: direct communication setting F13.08=7: the upper frequency limit is “7018H (communication setting of the upper frequency limit of torque control)”. The data range of 7018H is 0.00 - F00.16 (max. frequency). The upper frequency limit of torque control is used to set the maximum forward or reverse running frequency of the inverter in the torque control mode.
In the torque control mode, if the load torque is less than the output torque of the motor, the motor speed will rise continuously, and the maximum speed of the motor must be limited during torque control to prevent the mechanical system from galloping and other accidents; if the load exceeds the output torque of the motor and even the motor is drive to run reversely, the maximum operating load frequency of the motor is still restricted in the case ofF13.19=1 and not restricted in the case ofF13.19=0. The upper frequency limit of reverse running is dependent on F13.09 * F13.18. Example: The torque is set to be positive and the upper frequency limit of torque control is the AI1 analog input:
When the AI1 analog input is positive, the upper frequency limit corresponding to the forward speed limit is AI1 (percentage) * F13.09 and that corresponding to the reverse speed limit is AI1 (percentage) * F13.09 * F13.18; and when the AI1 analog input is negative, the upper frequency limit corresponding to the forward speed limit is AI1 (percentage) * F13.09 * F13.18 and that corresponding to the reverse speed limit is AI1 (percentage) * F13.09. Maximum operating frequency in torque control = upper frequency limit of torque control + offset of upper frequency limit (valid only when F13.08=1 to 5), but the maximum operating frequency is limited by the maximum frequency ofF00.16.
When the motor drives an object to move, it is necessary to overcome static/dynamic friction. You can set this group of parameters to enable the motor rotation at the specified torque while overcoming the inherent static/dynamic friction. The motor is mainly subject to static friction before rotation and dynamic friction after starting rotating. In short, the output performance of the motor is related to this group ofparameters.
