User Manual of EM730/EM730E Series Inverter F07.27=0: invalid The automatic voltage regulation (AVR) function is invalid. F07.27=1: valid The AVR function is continuously valid. If the input voltage is lower than the rated input voltage, and the output frequency is greater than the corresponding frequency on the VF curve, the inverter will output the output the maximum voltage to maximize the power output of the motor. If the input voltage is higher than the rated input voltage, the output voltage of the inverter will decrease, and the VF ratio will remain unchanged. F07.27=2: automatic The AVR function is valid automatically (invalid during deceleration):
the inverter will automatically adjust the output voltage according to changes in the actual grid voltage, to keep it at the rated output voltage. When the continuous stall time exceeds the set value of F07.28, the driver will report a stall protection. In the stall status, the driver will perform automatic control according to the set value of F07.29. The intensity setting depends on the on-site application, instead of maximization. 7.9 Multi-segment Speed and Simple PLC Parameter Group of F08 Group 207 Function Default Function code name Parameter description Unit Attribute code setting F07.27 AVR function 0: Invalid 1: valid 2:
