How to Configure PID control on ATV61 ?

Typical Configuration

The following example is typical of many PID control configurations.

We will configure the drive to run from a Start/Stop input, use the HMI for the PID Setpoint and a 4

– 20mA signal as the PID feedback. As an option we will included the ability to bypass PID control

and manually set the speed of the drive, this reference will come from a 0 – 10 volt signal.

Below in figure 1.2 are the input and output assignments that we want to achieve along with the

control wiring connections to be used. The connection of the Fault Indication Lamp and Motor

Frequency Meter are optional.

Looking at the Inputs and Outputs we see that starting and stopping is from LI1 (Logic Input 1), LI2

is a Fault Reset and as an option LI6 can be the Ref.2 channel (Manual Setpoint) select input. If

you choose not to use Ref.2 channel feature simply ignore “Step 5 - Ref.2 channel (Manual

Setpoint)” and leave LI6 disconnected.

The explanation on how to configure the above is laid out in the following steps.

STEP 1 – FACTORY SETTINGS

STEP 2 – CONFIGURE PID MACRO AND MOTOR NAMEPLATE

STEP 3 – CONFIGURE PID FEEDBACK SIGNAL

STEP 4 – REF.1 CHANNEL (INTERNAL PID SETPOINT)

STEP 5 – REF.2 CHANNEL (MANUAL SETPOINT)

STEP 6 – ADJUSTING INTERNAL PID SETPOINT

STEP 7 – SCALING PID FEEDBACK AND REFERNENCE


 

 

STEP 1 – FACTORY SETTINGS

1)       Navigate to Factory Settings menu as below.



STEP 2 – CONFIGURE PID MACRO AND MOTOR NAMEPLATE
1)      
Navigate to Simply Start Menu as below.

 

2) In the 1.1 SIMPLY START menu enter the Macro configuration screen and select PID regul, to

select this “Enter” must be held down for 2 seconds. Once configured, a tick will appear next to

“PID requl” verifying selection. See Below.



 

Continue down the 1.1 SIMPLY START menu and set motor nameplate, acceleration /

deceleration rates and speed limit parameters up as per normal commissioning, for more

information on these parameters consult the full technical manual.

 

STEP 3 – CONFIGURE PID FEEDBACK SIGNAL

1)       Navigate to Inputs / Outputs Menu as below.

 


 

2)       In the AI2 CONFIGURATION menu set “AI2 min. value” to 4.0mA as shown in the screen below.


STEP 4 – REF.1 CHANNEL (INTERNAL PID SETPOINT)

1) Now we will set up Ref.1 channel (PID Reference) to come from the HMI. Navigate to the

COMMAND menu shown below.




 

2) In the 1.6 COMMAND menu enter the Ref.1 channel screen and select HMI. Once configured, a

tick will appear next to “HMI” verifying selection



 

3) Still in the 1.6 COMMAND menu enter the Profile screen and select Separate, Once configured,

a tick will appear next to “Separate” verifying selection. See Below.




 

STEP 5 – REF.2 CHANNEL (MANUAL SETPOINT)

1) Still n the 1.6 COMMAND menu enter the Ref.2 switching screen and scroll down to select LI6,

Once configured, a tick will appear next to “LI6” verifying selection. See Below.


 

2) Still in the 1.6 COMMAND menu enter the Ref.2 channel and select AI1 (this is a 0 – 10v input),

Once configured, a tick will appear next to “AI1” verifying selection. See Below.



 

The drive is now configured with Ref.1 channel and Ref.2 channel selected via LI6, states as follows:

LI6=0, Ref.1, Internal PID Setpoint. ,  LI6=1, Ref.2, AI1 for Speed Reference


STEP 6 – ADJUSTING INTERNAL PID SETPOINT

To adjust the PID Setpoint navigate to Internal PID ref screen and set as required.




 

NOTE: Scrolling down further in the “1.2 MONITORING” menu allows PID feedback, PID error and

PID output to be viewed, this is useful during commissioning.

STEP 7 – SCALING PID FEEDBACK AND REFERNENCE

To Scale the PID Feedback Signal and PID Reference signal, navigate to PID REGULATOR

screen shown below.
