TECORP Electronics Manual CD143 Speed search time Set range:0.1—20.0S HC1-A User Unit:0.1S Factory setting:2.0 This parameter is set as speed search time when the inverter restarts by the speed search method after clearing the external faults or a momentary power less.For the starting and stopping of some large inertia load,because of its large inertia,if users restart the machine after its complete stop,it will waste much time.But using the speed search function,things are different.You needn’t wait for the machine’s fully stop,the inverter will make a frequency tracking from high to low at its set frequency.After tracking the inverter will continue to accelerate to reach the set frequency. CD144 Speed search current level Set range:0—200% Unit:1% Factory setting:150 When the inverter is making a speed search, If the output current is higher than this standard level, the inverter will decrease the frequency to make the current return to its normal range and then execute the command of speed search again. CD145 Restarting select after a momentary power loss Set range:0—1 Unit:1 Factory setting:0 0: invalid no auto restarting after a momentary power loss 1:restart by speed search Related introduction refer to CD143 CD146 Momentary power loss ride through time Set range:0.1—5.0S Unit:0.1S Factory setting:0.5 This setting determines the longest time allowable for momentary power loss.If it exceeds the allowable time; the inverter will still be in a stop state after the power recovery occurs. If users want to restart the inverter, you need to follow the normal starting steps again. CD147 Number of auto restarting attempt Set range:00—10 Unit:1 Factory setting:00 When meeting abnormal situations such as over current, over 59
