VLT AQUA Drive FC 202
Function:
This parameter defines which input
on the frequency converter should be
treated as the source of the reference
signal for the closed-loop 1 controller.
Analog input X30/11 and analog
input X30/12 refer to inputs on the
®
VLT General Purpose I/O Card MCB
101.
Function:
This parameter defines which input
on the frequency converter should
be treated as the source of the
feedback signal for the closed-loop 1
controller. Analog input X30/11 and
analog input X30/12 refer to inputs

on the VLT General Purpose I/O
Card MCB 101.

loop 1 controller.
3.18.3 21-2* Closed Loop 1 PID
21-20 Ext. 1 Normal/Inverse Control
Option: Function:
[0] Normal Reduces the output when feedback is higher than
*
the reference.
[1] Inverse Increase the output when feedback is higher than
the reference.
21-21 Ext. 1 Proportional Gain
Range: Function:
0.50 [0 - 10 ] The proportional gain contains the factor
*
indicating the number of times the error
between the setpoint and the feedback signal is
to be applied.
If the product error times gain jumps with a value equal to
what is set in parameter 3-03 Maximum Reference, the PID
controller tries to change the output speed equal to what
is set in parameter 4-13 Motor Speed High Limit [RPM]/
Function:
The setpoint reference is used in
extended 1 closed loop. Ext.1
Setpoint is added to the value
from the Ext.1 Reference Source
selected in parameter 21-13 Ext.
1 Reference Source.
Function:
Readout of the reference
value for the closed-loop
1 controller.
Function:
Readout of the feedback
value for the closed-loop
1 controller.
