6、Phase-sequence protection: When protector inspects wrong phase, response time≤2s (optional)；
7、 Protection of motor: this controller has five basic protection functions for main motor and fan's
①、 block protection： When working current reaches to from 4 times to 8 times of set current after
motor
②、Short circuit protection: when testing current reaches above 8 times of set current, response
finish starting, response time ≤0.2s；
③、Protection of phase failure: in case of phase failure of any one phase,
time≤0.2s；
④、Unbalance protection: when currents of any two phase differ 60～75%,
setup time；
⑤、Protection characteristics of reverse time limit of overload (time unit: second)，please see
set time；
following table（table 2.1.1） ，multiple＝I
motor operates with delay time according to overload factors and operation time shown in
following table (table 2.1.1) when motor's working current is larger or equal to from 1.2 times
and 3.0 times of set current.
