PID Feedback Signal

Program Feedback Feedback Settings
This parameter Enables/Disables PID feedback control. When enabled, this
parameter determines the source of the mo tor-control feedback.
Settings:
0 — PID Control Disabled
1 — V/I
2 — RR
3 — RX
4 — RX2 Option (AI1)
5 — Option V/I
6 — PG Feedback Option
Proportional-Integral-Derivative (PID) — A closed-loop control technique
that seeks error min imization by reacting t o three values: One t hat 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 — PID Control
Disabled
Changeable During Run — Yes

PID Feedback Delay Filter

Program Feedback 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 — Numeri cal
Factory Default — 0.1
Changeable During Run — Yes
Minimum — 0.0
Maximum — 25.0

PID Feedback Proportional (P) Gain

Program Feedback Feedback Settings
This parameter determines the degree that the Proportional function affects t he
output signal. The larger the value entered here, the quicker the drive responds
to changes in feedback.
Direct Access Number — F362
Parameter Type — Numeri cal
Factory Default — 0.10
Changeable During Run — Yes
Minimum — 0.01
Maximum — 100.0

PID Feedback Integral (I) Gain

Program Feedback Feedback Settings
This parameter determ ines 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 — Numeri cal
Factory Default — 0.10
Changeable During Run — Yes
Minimum — 0.01
Maximum — 100.00

PID Deviation Upper Limit

Program Feedback Feedback Settings
This parameter determines the maximum amount that the feedback may
increase the output sign a l.
Direct Access Number — F364
Parameter Type — Numeri cal
Factory Default — 60.00
Changeable During Run — Yes
Minimum — 0.00
Maximum — 60.00
Units — Hz
