User Manual of EM760 High-Performance Inverter When the bus voltage is lower than the instantaneous stop/non-stop action voltage (F07.08), the inverter will be in the power-down status. When the bus voltage is higher than the instantaneous stop/non-stop recovery voltage (F07.09), and the judgment time (F07.10) for the instantaneous stop/non-stop recovery voltage is up, the inverter will recover normal operation. When the ones place of the instantaneous stop/non-stop option ofF07.06 bus voltage control is set to “ 1: Slow down”, as shown in Fig. 6-40:
When the bus voltage is lower than the instantaneous stop/non-stop action voltage (F07.08), the inverter will slow down at the speed set based on the declaration time for the instantaneous stop/non-stop action (F07.30). When the bus voltage is higher than the instantaneous stop/non-stop recovery voltage (F07.09), the inverter will not slow down. When the cumulative time reaches the judgement time for instantaneous stop/non-stop recovery voltage (F07.10), the inverter will start to acceleration, and the frequency will gradually return to the set value. When the ones place of the instantaneous stop/non-stop option ofF07.06 bus voltage control is set to “2:
Slow down to stop”, the action is similar to that of the option 1. When the bus voltage reaches the instantaneous stop/non-stop action voltage, the speed set based on the instantaneous stop/non-stop slowdown time (F07.30) will constantly decrease to 0, regardless ofvoltage recovery.
