User Manual of EM730/EM730E Series Inverter As shown in the table below: Table 7-10 Detailed Definition of Protection Shield Bits For example: To shield the E07 protection, you only need to set the first bit corresponding to E07 to 1, i.e. F07.00=xxx xxx1x. To shield the E08 and E13 protection, you only need to set the 0 th bit corresponding to E08 and the 5 th bit corresponding to E13 to 1. That is, F07.00=xx1 xxxx1. Unless there are special needs, please do not shield any protection function, so as to prevent the inverter from damage as a result of protection failure.
the motor, sending an alarm of motor overload protection ( E13 ) if the duration reaches one The inverse time curve of motor overload protection is: 200% Ч (F07.01) Ч rated current of minute; 150% Ч (F07.01) Чrated current of the motor, sending an alarm of motor overload ( E13 ) if the duration reaches 15 minutes. The user needs to set F07.01 correctly according to the actual overload capacity of the motor. If the set value is too large, the motor may be damaged as a result of overheat but the inverter may not send an alarm! The F07.02 warning coefficient is used to determine the extent of motor overload for a protection warning. The larger this value, the less the warning is advanced.
When the cumulative output current of the inverter is greater than the product of the inverse time curve of load by F07.02, the multi-function digital DO terminal of the inverter will output the valid signal “17: Motor overload pre-alarm”. 200 Protection E20 * E13 E06 * E04 E07 E08 code Correspond 7 6 5 4 3 2 1 0 ing bit Settings 0/1 * 0/1 0/1 0/1 * 0/1 0/1 Function Default Function code name Parameter description Unit Attribute code setting F07.01 Motor overload protection gain 0.20 - 10.00 1.00 ● F07.02 Motor overload pre-alarm coefficient 50 - 100 % 80 ● Function Default Function code name Parameter description Unit Attribute code setting F07.06 Bus voltage control Ones place:
