Chapter 6 - Parameter Description

6.6 Application Group [APP]
%)**+B'1
APP-00 allows jumping
to any parameter in
APP group without scrolling to it. Press [ENTER]
key and input desired parameter code by using
[SHIFT] and [UP]/[DOWN] keys.
When [ENTER] key is pressed again, the desired
parameter will be on the display.
%)*+$89F
APP-01 parameter sets
the PID Feedback
scaling percentage. The default setting is 100% and
it is optimal for most applications. If it is set to a
higher number, the PID control will be more
responsive but can be unstable.
%)*+%':">"!
APP-02 parameter
enables APP-03 and
auxiliary reference mode for PID control.
%)*.+%':">"!-! !
APP-03 parameter has
nine selections for
auxiliary reference signal: Keypad-1, Keypad
Up/Down, V1, V1S, I, V1+I, Pulse, Int.485 and
Ext. PID. Refer to SET-10 parameter for detailed
description.
%)*/A*0+$89:''>"$6
!'!'
One of these three PID Feedback Max. Value
parameters will be available when corresponding
input is selected in SET-21. The value can be set
from 0 to maximum SET-04, SET-09 or SET-15.
%)*5+$"& &!<=
The Derivative
parameter of the PID
control allows creating an offset on the PID output
value based on rate of error change. In other words,
this parameter predicts a future error level and PID
adjusts its output to correct it.
%)+$' '
APP-12 setting
determines the PID
output scaling factor. The default is 100% and it is
optimal for most of the applications.
%).+$!)!
APP-13 setting
determines the PID
second P Gain value. The PID P gain will be
switched to P Gain 2 when digital input set to P-
Gain2 is activated. The default is 100%.
%)/+$!
APP-14 setting
determines the PID P-
Gain and P Gain 2 scaling factor. The default is
100%.
%)3+$891'"& !
APP-17 setting
switches the PID
feedback curve to U type. If VFD control is set to S
curve, the APP-17 can be set to Yes to match control
and feedback curves.
1$
%)*6+!%!
The VFD will switch control to second settings
when digital input set to 2nd Function is activated.
APP-20- The second acceleration time setting.
APP-21- The second deceleration time setting.
