EXT1/EXT2 SEL
-5...12 1 0
Defines the source for selecting between the two external control locations EXT1 or
EXT2. Thus, defines the source for Start/Stop/Direction commands and reference
signals.
0 = EXT1 – Selects external control location 1 (EXT1).
• See parameter 1001 EXT1 COMMANDS for EXT1’s Start/Stop/Dir definitions.
• See parameter 1103 REF1 SELECT for EXT1’s reference definitions.
1 = DI1 – Assigns control to EXT1 or EXT2 based on the state of DI1
(DI1 activated = EXT2; DI1 de-activated = EXT1).
2…5 = DI2…DI5 – Assigns control to EXT1 or EXT2 based on the state of the
selected digital input. See DI1 above.
7 = EXT2 – Selects external control location 2 (EXT2).
• See parameter 1002 EXT2 COMMANDS for EXT2’s Start/Stop/Dir definitions.
• See parameter 1106 REF2 SELECT for EXT2’s reference definitions.
8 = COMM – Assigns control of the drive via external control location EXT1 or EXT2
based on the fieldbus control word.
• Bit 5 of the Command word 1 (parameter 0301 FB CMD WORD 1) defines the
active external control location (EXT1 or EXT2).
• See Fieldbus user’s manual for detailed instructions.
9 = TIMER 1 – Assigns control to EXT1 or EXT2 based on the state of the Timer
(Timer activated = EXT2; Timer de-activated = EXT1. See Group 36: Timed
functions.
10…12 = TIMER 2… 4 – Assigns control to EXT1 or EXT2 based on the state of the
Timer. See TIMER 1 above.
-1 = DI1(INV) – Assigns control to EXT1 or EXT2 based on the state of DI1
(DI1 activated = EXT1; DI1 de-activated = EXT2).
-2…-5 = DI2(INV)…DI5(INV) – Assigns control to EXT1 or EXT2 based on the state of
the selected digital input. See DI1(INV) above.
