0.0…10.0 s Filter time constant. If parameter value is set to zero, the derivative filter is
disabled.
4005 ERROR VALUE INV Selects the relationship between the feedback signal and drive speed (drive
output frequency).
0 = NO
NO Normal: A decrease in feedback signal increases drive speed (drive output
frequency). Error = Ref - Fbk
0
YES Inverted: A decrease in feedback signal decreases drive speed (drive output
frequency). Error = Fbk - Ref

4006 UNITS Selects the unit for PID controller actual values. 4 = %
0…12 See parameter 3405 OUTPUT1 UNIT selections NO UNIT…mV.
4007 UNIT SCALE Defines the decimal point location for the display parameter selected by
parameter 4006 UNITS.

4008 0% VALUE Defines together with parameter 4009 100% VALUE the scaling applied to
the PID controller’s actual values.

x…x Unit and range depend on the unit and scale defined by parameters 4006
UNITS and 4007 UNIT SCALE.
4009 100% VALUE Defines together with parameter 4008 0% VALUE the scaling applied to the
PID controller’s actual values.

DI3U,4D(RNC) 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.
