Description
Filter time constant. If parameter value is set to zero, the derivative filter is
disabled.
Selects the relationship between the feedback signal and drive speed (drive
output frequency).
Normal: A decrease in feedback signal increases drive speed (drive output
frequency). Error = Ref - Fbk
Inverted: A decrease in feedback signal decreases drive speed (drive output
frequency). Error = Fbk - Ref
Selects the unit for PID controller actual values.
See parameter 3405 OUTPUT1 UNIT selections NO UNIT...mV.

Potentiometer.
Digital input DI3: Reference increase. Digital input DI4: Reference decrease.
Stop command resets the reference to zero. When this selection becomes
active (in change from EXT1 to EXT2), the reference initializes to the value
used when this control location (and this selection) was active the last time.
