If (Error x Gain) jumps with a value equal to what is set in par.20-14
troller will try to change the output speed equal to what is set in par. 4-13/4-14, Motor Speed High Limit, but in
practice of course limited by this setting.
The proportional band (error causing output to change from 0%–100%) can be calculated by means of the for-

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 par.
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.
Function:
Readout of the output value for the closed-loop 1 controller.
Function:
Normal
Select [0] if the output should be reduced when feedback is higher
than the reference.
Inverse
Select [1] if the output should be increased when feedback is
higher than the reference.
