User Manual of A90 Series Inverter Voltage of overvoltage stall Invalid voltage of DC bus voltage overvoltage stall Output frequency Treatment of regenerated overvoltage Time Fig. 7-23 Schematic Diagram of Overvoltage Stall Protection When the bus voltage is lower than the voltage of undervoltage stall control (F07.08), the inverter will be in the power-down status. When the bus voltage is greater than the voltage of power failure end judgment (F07.09) and this lasts for the delay time of power failure end judgment (F07.10), the inverter will recover its normal status. F07.11=0: invalid The current limit does not work. F07.11=1: limit mode 1 F07.11=2:
limit mode 2 When the output current reaches the current limit level (F07.12) and the current limit 184 Function Default Function code name Parameter description Unit Attribute code setting F07.09 Instantaneous stop/no-stop recovery voltage Instantaneous stop/no-stop operating voltage to 100.0 % 86.0 ● F07.10 Check time for instantaneous stop/no-stop recovery voltage 0.00-100.00 s 0.5 ● Function Function code Default Parameter description Unit Attribute code name setting F07.11 Current limit control 0: Invalid 1: limit mode 1 2: limit mode 2 2 ○ F07.12 Current limit level 20.0-180.0 (100% = rated current of inverter) % 150.0 ●
