This group defines:
• how the drive selects between command sources
• characteristics and sources for
REF1 and REF2.
Group 11: Reference Select
Code Description Range Resolution Default S
1101 KEYPAD REF SEL 1, 2 1 1 [REF1(Hz/rpm)]
Selects the reference controlled in local control mode.
1 =
REF1(Hz/rpm) – Reference type depends on parameter 9904 MOTOR CTRL MODE.
• Speed reference (rpm) if 9904 = 1 (
VECTOR:SPEED) or 2 (VECTOR:TORQ).
• Frequency reference (Hz) if 9904 = 3 (
SCALAR:FREQ).
2 =
REF2(%)
1102 EXT1/EXT2 SEL -6…12 1 0 (EXT1) 
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…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 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) defines 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 Group 36: TIMED FUNCTIONS.
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.
