ACH550-01 User's Manual

4010 SET POINT SEL 0…20

Defines the reference signal source for the PID controller.

• Parameter has no significance when the PID regulator is by-passed

(see 8121

REG BYPASS CTRL).

0 =

KEYPAD – Control panel provides reference.

1 =

AI1 – Analogue input 1 provides reference.

2 =

AI2 – Analogue input 2 provides reference.

8 =

COMM – Fieldbus provides reference.

9 =

COMM+AI1 – Defines a fieldbus and analogue input 1 (AI1)

combination as the reference source. See Analogue input reference

correction on page 276.

10 =

COMM

AI1 – Defines a fieldbus and analogue input 1 (AI1)

combination as the reference source. See Analogue input reference

correction on page 276.

11 =

DI3U,4D(RNC) – Digital inputs, acting as a motor potentiometer

control, provide reference.

•

DI3 increases the speed (the U stands for “up”)

•

DI4 decreases the reference (the D stands for “down”).

• Parameter 2205

ACCELER TIME 2 controls the reference signal’s rate

of change.

•

R = Stop command resets the reference to zero.

•

NC = Reference value is not copied.

12 =

DI3U,4D(NC) – Same as DI3U,4D(RNC) above, except:

• Stop command does not reset reference to zero. At restart the motor

ramps up, at the selected acceleration rate, to the stored reference.

13 =

DI5U,6D(NC) – Same as DI3U,4D(NC) above, except:

• Uses digital inputs

DI5 and DI6.

14 =

AI1+AI2 – Defines an analogue input 1 (AI1) and analogue input 2

(

AI2) combination as the reference source. See Analogue input

reference correction on page 276.

15 =

AI1

AI2 – Defines an analogue input 1 (AI1) and analogue input 2

(

AI2) combination as the reference source. See Analogue input

reference correction on page 276.

16 =

AI1-AI2 – Defines an analogue input 1 (AI1) and analogue input 2

(

AI2) combination as the reference source. See Analogue input

reference correction on page 276.

17 =

AI1/AI2 – Defines an analogue input 1 (AI1) and analogue input 2

(

AI2) combination as the reference source. See Analogue input

reference correction on page 276.

19 =

INTERNAL – A constant value set using parameter 4011 provides

reference.

20 =

PID2OUT – Defines PID controller 2 output (parameter 0127 PID 2

OUTPUT) as the reference source.
