Drive control parameters After the Modbus communication has been set up, the drive control parameters listed in the table below should be checked and adjusted when necessary. The Setting for fieldbus control column gives the value to use when the Modbus interface is the desired source or destination for that particular signal. The Function/Information column gives a description of the parameter. Parameter

FORWARD Enables the rotation direction control 40031 REVERSE as defined by parameters 1001 and bit 2 REQUEST 1002. The direction control is explained in section Reference handling on page 311. COMM Enables jogging 1 or 2 activation 40032 through 0302 FB CMD WORD 2 bits bits 20…21 (JOGGING 1 / JOGGING 2). 20…21 COMM Enables EXT1/EXT2 selection 40001 40031 through 0301 FB CMD WORD 1 bit 5 bit 11 bit 5 (EXT2); with the ABB drives profile 5319 EFB PAR 19 bit 11 (EXT CTRL LOC). 40002 for REF1 COMM Fieldbus reference REF1 is used COMM+AI1 when EXT1 is selected as the active COMM*AI1 control location. See section Fieldbus references on page 308 for information on the alternative settings. COMM Fieldbus reference REF2 is used 40003 for REF2 COMM+AI1 when EXT2 is selected as the active COMM*AI1 control location. See section Fieldbus references on page 308 for information on the alternative settings.
