Therefore, detecting exactspeed is difficult.The following table shows 4 types of Speed search selection.H22 Speed searchduring H20 –[Power ON start]Speed searchduring InstantPower FailurerestartSpeed searchduring H21-[Restart afterfault reset]Speed searchduringAccelerationBit 3 Bit 2 Bit 1 Bit 00 - - - -1 - - - 2 - - -3 - - 4 - - -5 - - 6 - -7 - 8 - - -9 - - 10 - -11 - 12 - -13 - 14 -15 H23: Limits current during Speed search.
