User Manual of EM730 Series Inverter stop the output and enter the protection status. Bit setting = 0: when the inverter detects the protection corresponding to this bit, it will Bit setting = 1: when the inverter detects the protection corresponding to this bit, it will keep the original status without protection. This code is subject to bit operation. You only need to set the corresponding bit to 0 or 1. 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. and the 5 th bit corresponding to E13 to 1. That is, F07.00=xx1 xxxx1.
To shield the E08 and E13 protection, you only need to set the 0 th bit corresponding to E08 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 inverse time curve of motor overload protection is: 200% Ч (F07.01) Ч rated current of the motor, sending an alarm of motor overload protection ( E13 ) if the duration reaches one 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 219 0: valid protection 1: shielded protection 00 Protection code E20 * E13 E06 * E04 E07 E08 Correspond ing bit 7 6 5 4 3 2 1 0 Settings 0/1 * 0/1 0/1 0/1 * 0/1 0/1 Function code Function code name Parameter description Unit Default setting Attribute Mailing address F07.01 Motor overload protection gain 0.20 ~ 10.00 1.00 ● 0x0701 F07.02 Motor overload pre-alarm coefficient 50 ~ 100 % 80 ● 0x0702
