User Manual of EM730 Series Inverter protection retries will be performed from zero. In case of any trip protection within this period, protection retries will be carried out based on the last count. With regard to some protections, the action mode of the inverter can be selected via this function code. The inverter will stop running freely when the corresponding bit is set to 0 and according to the stop mode (F04.19) when the corresponding bit is set to 1. These two function codes are subject to bit operation. You only need to set the corresponding bit to 0 or 1. As shown in the table below: Table 7-11 Detailed Definition of Protection Action Bits For example:
To stop the inverter according to the stop mode (F04.19) after the E08 and E13 protection is enabled, 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.
