Description
V/f V/f w PG OLV OLV
OLV/PM AOLV/PM CLV/PM
Sets the output voltage limit operation determined by C3-18 (percentage
modulation) when C3-05 is enabled.
Note: This parameter is only available in models CIMR-Ao4A0930,
4A1200, and A1000 HHP.
V/f V/f w PG OLV OLV
OLV/PM AOLV/PM CLV/PM
Sets the maximum percentage of output voltage reduction when C3-05 is
enabled.
Note: This parameter is only available in models CIMR-Ao4A0930,
4A1200, and A1000 HHP.
V/f V/f V/f w PG OLV OLV
OLV/PM AOLV/PM CLV/PM
Sets the slip compensation gain used for motor 2.
V/f V/f V/f w PG OLV OLV
OLV/PM AOLV/PM CLV/PM
Sets the slip compensation delay time used for motor 2.
V/f V/f V/f w PG OLV OLV
OLV/PM AOLV/PM CLV/PM
