User Manual of A90 Series Inverter Table 7-9 Detailed Definition of Action Bits after Failure For example: To stop the inverter according to the stop mode (F04.19) after the E08 and E13 failure, you only need to set the 1 st bit corresponding to E08 and the 3 rd bit corresponding to E13 to 1. That is, F07.19=xxx x1x1x. When the off-load protection is valid (F07.21=1), the inverter will be in the running status without DC braking, and the output current is below the off-load detection level (F07.22) and maintained for the off-load detection time (F07.23), the inverter will be in the off-load status. Specific processing depends on F07.24. 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 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. 187 F07.19 E21 E16 E15 E14 E13 E12 E08 E07 F07.20 * * * * E28 E27 E25 E23 Correspond 7 6 5 4 3 2 1 0 ing bit Settings 0/1 0/1 0/1 0/1 0/1 0/1 0/1 0/1 Function Default Function code name Parameter description Unit Attribute code setting F07.21 Options of load loss protection 0: invalid 1: valid 0 ● F07.22 Load loss detection level 0.0-100.0 % 20/1000 ● F07.23 Load loss detection time 0.0 - 60.0 s 1.0 ● F07.24 Options of load loss protection action 0: fault reporting and free stop 1: fault reporting and stop according to the stop mode 2:
