Table 9: Group 11: Reference Select
Code Description Range Resolution Default S
1102 EXT1/EXT2 SEL -6…12 1 0 (EXT1)
Denes the source for selecting between the two external control locations EXT1 or EXT2. Thus, denes 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 denitions.
• See parameter 1103, page 22 REF1 SELECT for EXT1’s reference denitions.
1 = DI1 – Assigns control to EXT1 or EXT2 based on the state of DI1 (DI1 activated = EXT2; DI1 de-activated = EXT1).
2…6 = DI2…DI6 – 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 denitions.
• See parameter 1106 REF2 SELECT for EXT2’s reference denitions.
8 = COMM – Assigns control of the drive via external control location EXT1 or EXT2 based on the eldbus control word.
• Bit 5 of the Command Word 1 (parameter 0301) denes the active external control location (EXT1 or EXT2).
• See Fieldbus user’s manual for detailed instructions.
9 = TIMED FUNC 1 – Assigns control to EXT1 or EXT2 based on the state of the Timed Function (Timed Function activated = EXT2; Timed Function de-
activated = EXT1). See on page 35.
10…12 = TIMED FUNC 2…4 – Assigns control to EXT1 or EXT2 based on the state of the Timed Function. See TIMED FUNC 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…-6 = DI2(INV)…DI6(INV) – Assigns control to EXT1 or EXT2 based on the state of the selected digital input. See DI1(INV) above.
