ExtPID1Unit
*
[-999999.999 -

ExtPID1Unit]
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
.

Function:
0 ExtPID1Unit

0 ExtPID1Unit
*
[-999999.999 -

Range:
Function:

21-20 Ext. 1 Normal/Inverse Control
Option:
Function:
[0]
*
Normal Reduces the output when feedback is higher than
the reference.

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]
