3.1.16 Creep Threshold of Phase Current
For each phase with a current less than threshold CREEP_THRESHOLD_I in any one line cycle interval, any contributions to a selected pulse are zeroed out, and quantities from that phase make no contribution toward any selected pulse and its associated pulse accumulator.
The CREEP_THRESHOLD_I is stored in the uQ12.20 format and the unit is mArms-scaled (normalized by a common K_I). A single common K_I is used for all phases for CREEP_THRESHOLD_I determination.
For example, for a desired creep threshold of 10 mA, K_I = 617.28396, then CREEP_THRESHOLD_I = round[(10 / 617.28396) * 220] = 16987 = 0x0000425B.
Warning: The CREEP_THRESHOLD_I functionality will be
deactivated if any of the registers CREEP_THRESHOLD_I_A, CREEP_THRESHOLD_I_B, or CREEP_THRESHOLD_I_C contain a value other than zero.
