Default

1101 KEYPAD REF SEL

1,2

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) .

• Frequency reference (Hz) if 9904 = 3 (SCALAR; FREQ) .

2 = REF2 (%)

1102 EXT1/EXT2 SEL

- 6 . . .12



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 = 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, Timer 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…-6 = DI2(INV)…DI6(INV) – Assigns control to EXT1 or EXT2 based on the state of the selected digital input . See DI1(INV) above .
