Decrease the value if the motorbegins to oscillate, and increase the value if it takes too long forthe current reference to equal the output current.Default: 5.0 sMin.: 0.0Max.: 100.0 –n8-48(53B) Pull-In Current PM No-load CurrOLV/PMOLV/PMDefines the d-Axis current reference during no-load operationat a constant speed. Set as a percentage of the motor ratedcurrent.
