PID Feedback Selection
Program

Feedback Settings
This parameter is used to select the source of the feedback control. When enabled
at parameter
F359 , this parameter determines the source of the motor-control
feedback or it may be set to the fixed value of zero.
Settings:
0 — Feedback Value = Zero
1 — V/I
2 — RR
3 — RX
4 — RX2 (AI1)
5 — Option V/I (AI2)
6 — PG Feedback
Proportional-Integral-Derivative (PID) — A closed-loop control technique that
seeks error minimization by reacting to three values: One that is proportional to
the error, one that is representative of the error, and one that is representative of
the rate of change of the error.
Direct Access Number — F360
Parameter Type — Selection List
Factory Default — Feedback Value =
Zero
Changeable During Run — Yes
PID Feedback Delay Filter
Program

Feedback Settings
This parameter determines the delay in the ASD output response to the motor-
control feedback signal (Signal source is selected at
F360 ).
Direct Access Number — F361
Parameter Type — Numerical
Factory Default — 0.1
Changeable During Run — Yes
Minimum — 0.0
Maximum — 25.0
PID Feedback Proportional (P) Gain
Program

Feedback Settings
This parameter determines the degree that the Proportional function affects the
output signal. The larger the value entered here, the quicker the drive responds to
changes in feedback.
Direct Access Number — F362
Parameter Type — Numerical
Factory Default — 0.10
Changeable During Run — Yes
Minimum — 0.01
Maximum — 100.0
PID Feedback Integral (I) Gain
Program

Feedback Settings
This parameter determines the degree that the Integral function affects the output
signal. The smaller the value here, the more pronounced the effect of the integral
function on the output signal.
Direct Access Number — F363
Parameter Type — Numerical
Factory Default — 0.10
Changeable During Run — Yes
Minimum — 0.01
Maximum — 100.00
PID Deviation Upper-Limit
Program

Feedback Settings
This parameter determines the maximum amount that the feedback may increase
the output signal.
Direct Access Number — F364
Parameter Type — Numerical
Factory Default — 60.00
Changeable During Run — Yes
Minimum — 0.00
Maximum — 60.00
Units — Hz
