DI1 Digital input DI1. 0 = EXT1, 1 = EXT2. 1
DI2 See selection DI1.2
DI3 See selection DI1.3
DI4 See selection DI1.4
DI5 See selection DI1.5
EXT2 EXT2 active. The control signal sources are defined by
parameters 1002 EXT2 COMMANDS and 1106 REF2
SELECT.

COMM Fieldbus interface as the source for EXT1/EXT2 selection,
ie control word 0301 FB CMD WORD 1 bit 5 (with ABB
drives profile 5319 EFB PAR 19 bit 11). The control word is
sent by the fieldbus controller through the fieldbus adapter
or embedded fieldbus (Modbus) to the drive. For the control
word bits, see sections DCU communication profile on page
320 and ABB drives communication profile on page 315.

TIMED FUNC 1 Timed EXT1/EXT2 control selection. Timed function 1 active
= EXT2, timed function 1 inactive = EXT1. See parameter
group 36 TIMED FUNCTIONS.
